User questions & answers

Question:	Can you use the charger on the Energizer Power Plus NiMH AA Rechargeable Batteries rated at 2300 mAh
Answer:	You could if it actually worked. This charger stopped working within a month. I returned mine. Also you might want to consider more battery slots. 4 seems ok at first but now I got 1 with 8 slots and I think it's too small.
Question:	Does this charger only charge in pairs? Is it possible to charge 1 cell (at a time) with this charger
Answer:	I have owned this. The universal charger WILL charge batteries individually. There are 4 charging 'points' and you can choose to put one small battery (AA or AAA) in one point. Of course, you can also put two small batteries in each point to get the full 8-at-a-time figure. This also only applies to the small batteries. Cs and Ds are charged individually in each point, so their max is only 4 at a time total.
Question:	Can this charge aa and aaa at the same time
Answer:	Yes. AAA on one side and AA on the other. Not on the same side at the same time.
Question:	Can i use Energizer CHRPROWB4 Pro Charger with 240 volts 50 Hz AC input
Answer:	Hi Nikhil Singh, over at the Energizer web site they have some additional information. Look under batteries and then battery chargers. You can download the user manual for this model. The user manual clearly indicates that 240V 50Hz power is OK. The only problem you will have is the plug. The two-prong plug is designed for U.S. outlets. Of course, any plug adapter will solve that problem.Basically, the answer is yes.

User questions & answers

Question:	hey i want to know if the batteries on the charger come fully charge...since i connect them when i received my charger and the red light never change
Answer:	The Google preview of this item shows "AmazonBasics AA High-Capacity Rechargeable Batteries (8-Pack) ... Ni-MH Pre-Charged Rechargeable Batteries provide the extra power you need . .... of about 2500 mAh, but two of the batteries are only 54-70% of the rating." but you are correct. When I click the link, that spec is nowhere to be found. I use these for wireless microphones at my church. They work great. The nubs are slightly short so I do have to seat them in really good but they are excellent.
Question:	What does the pulsing red light 'bad battery" mean? Just a discharged or truly bad battery that won't accept / hold a charge
Answer:	To clarify, there are three different versions of AmazonBasic rechargeable NiMH batteries:- The original AmazonBasics batteries came in black wrappers. They are made in China and have the capacity rating of 2000mAh. They are NOT as good as Sanyo eneloop batteries.ASIN:B0030T1NEA AmazonBasics AA NiMH Pre-Charged Rechargeable Batteries- The second version of AmazonBasics batteries came in white wrappers. They are made in Japan and also have the capacity rating of 2000mAh. They are (according to me) rebranded 2nd-gen Sanyo eneloop, so you can expect at least 1500 cycles lifespan.ASIN:B00CWNMV4G AmazonBasics Pre-Charged Rechargeable Batteries- The third version is also black but called 'high-capacity'. They are (according to me) rebranded Sanyo XX. They are rated 2400mAh, but actual capacity is around 2550mAh, just like Sanyo XX. The rated lifespan of the XX is only 500 cycles.ASIN:B00HZV9TGS AmazonBasics High-Capacity Pre-Charged Rechargeable Batteries
Question:	Has anyone else had a problem with these? I had them plugged in for over 12 hours and the light never turned green
Answer:	I purchased the white label 1900mAh batteries and black labeled 2000mAh batteries several years ago. Contrary to other's comments, the white batteries are still charging up to full capacity, and the black batteries have all lost significant capacity. White labels say "made in japan" and black labels "made in china". Mfg Date of black batteries is AUG2014, and white batteries have "201409" imprinted. These have all been charged in the same MH-C9000 WizardOne from the beginning.
Question:	does it matter which slot tbe batteries are in? my old chsrger had to use the middle slots if only charging 2 for instance
Answer:	1a would be .5 C with these 2000mah cells.. I checked the IR of these cells and with my Turbo Matched 30 from Competition Electronics (these are a 1500 dollar cell matching system that we professional RC on road and off road car and truck guys used to match cells. Very important and HIGH TECH for the time system. Was made for Nicd cells but worked equally well on Nimh cells when they came out) and matched them to get well matched pairs for practice cells for Mod Mini Z cars and boats.. I used Enloop cells for race days and practice with these.. these cells give a solid 2050 to 2100mah handle, will give me long run times and with cells matched with a 6 amp discharge will give me a avg voltage of about 1.02v per cell over 25 minutes, my well massaged Eneloop 2kMah cells i match at 8.5 amps they give me a avg May of 1980 to 2020mah and will hold a avg Voltage of 1.06V per cell at 8.5 amp load over 25 minutes. Point is these cells are a very good value, even in high load usage these cells stand up a lot better then similarly priced Nimhs from other brands.. these cells offer 85% the performance of Eneloop at less then half the cost.. the cells hold up well until about 200 cycles then they deff start to have noticablly lower avg voltage over time at the same discharge curve.. but that's in higher load apps then most people will be using them for.. I charge these cells at .75C or 1.5 amps, at 1.5 amps the cells are slightly warm off the charger and that's how I want them, slightly warm when ready to run as the IR will be lower with a warm cell over a room temp one giving me less voltage sag as the cell warms up under load... These cells will be slightly above ambient temp of charged at .5C or 1 amp, the warmth will start to happen once the cell reaches about 90^% full charge and progressively get warmer until peak charge.. at .75C charge or 1.5 amps you will notice the cells are a fair bit warmer then ambient temp and this has it's use for high load apps like my Mini Z's and some times I'll even charge them at 1C or 2 amps.. that will make for a fairly hot pack BUT will give me the highest voltage under load for the first 25 to 30% of the charge... but will ABSOLUTELY shorten the cells life and I would not recommend doing that UNLESS you know what you are doing to the cell and understand the cells life will be cut by good bit.. meaning if I get 200 really good cycles on a set of cells when charging them at .75C or 1.5 amps, moving to a 1C or 2 amp charge will know it's really good cycles life down to 100 to 125... but you will have less voltage sag/higher voltage under load taking the very warm cells off the charger and straight to using them then if you was to charge them at a lower rate and have cooler cells... Charge at 1 amp and you will be happy with these cells .5C and under will give you the longest cell life for sure..

User questions & answers

Question:	My 4 batteries were losing charge so I put them in the charger. The lights are green. Do they have to be completely dead for them to recharge
Answer:	If your batteries are a few years old (or have been over-charged routinely), they may have developed high internal resistance. When used in a photoflash unit, for example, they will give very slow refresh time since the terminal voltage is lower under load. But when you put them in a charger, the terminal voltage becomes higher due to charging current. So the EBL charger (which is not very smart) considers those batteries as fully charged, even through they are not.You should get some better quality rechargeable batteries (such as Panasonic eneloop) to use in your photoflash unit.
Question:	Can you charge different mAh batteries at a time? Lets say I have four 2000mAH and four 2300mAH batteries, do I have to charge these separately
Answer:	I would think they can be charged together. The mAh value simply is an indication of the length of time the battery will operate. It has nothing to do with out put current or voltage. The 2300 may take a bit longer to charge than the 2000, but I cannot say for sure that would be the case. I would put the 2000's together and the 2300's together. Don't put one size next to the other size.
Question:	How long does it take to fully charge batteries
Answer:	Charge time is determined by the capacity of the batteries divided by charging current. The charging current of EBL 808A is very low at 200mA. So to recharge a pair of 2800mAh batteries at 200mA will take at least 14 hours.
Question:	can it charge uneven amount of batteries (1, 3, 5...)? Can you recommend any charger to charge 3 batteries? AA or AAA
Answer:	This charger can only charge in pairs, but we do have some other chargers that can charge uneven amount of batteries, here are the links: 1. http://www.amazon.com/gp/product/B00KBQ7U102. http://www.amazon.com/EBL-Battery-Rechargeable-Batteries-Released/dp/B00OT7HSBO3. http://www.amazon.com/EBL%C2%AE-Universal-Discharger-Rechargeable-Batteries/dp/B00IHT2AUE/ref=sr_1_11?s=hpc&ie=UTF8&qid=1399165294&sr=1-11&keywordsYou can choose your favorite ,may it help you!

User questions & answers

Question:	does it discharge batteries
Answer:	The EBL808U does not discharge batteries. There are other models that have a “refresh” function that will fully discharge batteries.
Question:	Is it dual voltage
Answer:	No it's 120v only sorry but they are amazing
Question:	Is there a distinction between the two usb ports? one is listed as 2.1a and the other 1.0a. will this effect their use
Answer:	Yes. 1.0A is a 1.0 Amp outlet, and the other is 2.1 Amps. Larger devices, such as late model phones and tablets will charge much faster at 2.1 Amps, but small devices, like bluetooth headsets & watches can easily charge at 1.0 Amp.
Question:	v or 1.5v
Answer:	Advertising mumbo. The 1.5 alkaline batteries are only 1.5 at the very beginning and go downhill just like a ski slope, ending around .08 and dead. The “1.2” is pretty honest. The discharge curve of rechargeables stays above 1.2 for much longer.

User questions & answers

Question:	Do both triple A and double A batteries come with the charger
Answer:	The Sanyo/Panasonic eneloop cells can be recharged in any good-quality charger designed for NiMH batteries.For best battery lifespan, choose a 'smart' charger that has a charge time between 2 and 5 hours.Avoid slow, timer-based dumb charger that will over-charge your batteries, and 'ultra-fast' 30-minute chargers that will over-heat your batteries.
Question:	This listing says: “for free adapter, please go to promotion” - there is no promotion tab. send me a 2v adapter as this listing states
Answer:	I use & prefer the Maha C9000 charger. It charges, conditions your batteries and displays all the info you need to tell you the state of any AA & AAA battery.
Question:	Can this recharge any brand of rechargeable battery such as energizer, Amazon, or Duracell
Answer:	The enloop charger will work with NiCads, NiMh, and some of the newer AA sized Li ion rechargeable batteries as long as the resting battery voltage is 1.25VDC. Do not drain your batteries past .9 volts, as this will reduce the number of recharge cycles possible in the battery. NEVER run rechargeable batteries completely flat (0.0 V) because there is a big possibility that you will destroy them.
Question:	How come the red light is flashing when I charge 5 or above AA batteries? 4 batteries are fine (red light no flashing
Answer:	Some newer solar lights use lithium batteries, ( 3.7 volts ). If your present batteries are 1.2 volt NiMH ( Nickle Metal Hydride ) or 1.2 volt NiCd ( Nickle-Cadmium ) these are OK ( if they fit ). My various new & old solar lamps use AA, AAA or half-length batteries. Best one recharges my AA's for flashlights. I also recharge disposable alkaline AA's, believing it's Very low charging rate will not explode them.

User questions & answers

Question:	Hi can we use eneloppe panasonic rechargeable batteries with the charger
Answer:	This Tenergy TN438 Smart Battery Charger will work with other brands of batteries as long as they are rechargeable AA/AAA size and are NiMH/NiCd type.
Question:	How long does it take to charge batteries
Answer:	this will depend on the capacity of the battery and the state of charge it currently has.
Question:	Will it charge any brand of battery
Answer:	I have several brands of rechargeable AA and its works for all of them. They will not all recharge by the same time. I try to keep the same type together.
Question:	what does charge error mean? It is not addressed in the instructions
Answer:	It mean that the charger has analyzed the voltage change between charging and discharging. It is constantly performing tests on the batteries. It has decided that the battery is not holding a charge as well as it expected the battery to do. Unfortunately, this charger is too sensitive and gives up on batteries that still have a lot of useful life left in them. You can't use this to charge batteries that are more than a couple of years old or batteries made by different manufacturers. I don't think there is a way to defeat the error message and still charge the batteries.

User questions & answers

Question:	Will this recharger charge my Duracell rechargeable batteries
Answer:	As long as the batteries are Ni-MH or Ni-CD it will charge them. I have EBL, Energizer and Rayovac brand Ni-MH batteries and it charges them all with no issues.
Question:	Can this unit also recharge AA/AAA Li-ion batteries? (The description indicates that it can only recharge 9v Li-ions
Answer:	No. This charger will charge only NiMH and NiCd AA/AAA batteries. The only Li-ion batteries it will charge are the 9v type. This is due to the voltages involved. AA/AAA NiMH/NiCd batteries contain a single 1.2v cell The cell's nominal voltage is determined by the its chemistry. For NiMH/NiCd cells, this value is 1.2v. A charger will push this up to ~1.4v. As the batteries discharge, this quickly drops to ~1.2v, flattens out there for most of their useful charge life, and the drops off from there as it becomes discharged. This charger is set up to charge AA/AAA batteies with NiMH/NiCd, and will stop charging (reverting to a trickle charge) once the battery charge reaches 1.4v. 9v batteries work a bit differently - they contain multiple cells connected in series to multiply their effective voltage. NiMH/NiCd 9v batteries will contain six to eight 1.2v cells, yielding an effective 7.2v to 9.6v at the battery terminals. Li-ion 9v batteries will typically contain two 3.7v cells, yielding an effective 7.4v at the battery terminals. This charger can handle any of these three because each of them are charged to the same (or similar) voltage, probably about 7.4v. So, long story made short: this charge works with only NiMH and NiCd AA/AAA batteries, but NiMH, NiCd, and Li-ion 9v batteries.
Question:	What is the charging time for aa and aaa batteries
Answer:	The charging time is dependent on the capacity of the batteries you are charging as well as the type. As Simran said, quick charging is not good for your batteries and plus I believe that by charging slower, you are able to actually store more energy in the battery. I only fast charge when I absolutely have to. I would never recommend to anyone to buy a fast-charge only charger.
Question:	Is this charger better than the one that's
Answer:	The $9.99 one must charge in pairs. If charging in pairs is not an issue then the $9.99 one is fine. This one will still require you to charge in pairs if the current charge for the battery is too low, otherwise it can recharge rechargeables individually. This particular model will also charge rechargeable 9v batteries (not that I've seen a lot of 9v rechargeables) and has an extra two slots for AA/AAA for a total of 10 AA/AAA bays. The $9.99 charger does not have a display to indicate the charging progress; you'll just have to wait till the green light shuts off indicating that the charge is complete. I have devices that uses an odd number of batteries, so this device works great for me. Brands tested on this unit without issues (AA and AAA): Rayovac, Duracell, Energizer, EBL, Eneloop, and Panasonic

User questions & answers

Question:	how long does it take to charge a battery
Answer:	It's based on usage. Deep discharged cycles on the regular basis (discharged under 30%) will use up cycles but if you regularly charge them when they are about 1.15volts (or higher) they can last quite a long time long as they are not overcharged all the time or charged in a simple charger. If you want the best out of these batteries i suggest getting a smart charger such as http://www.amazon.com/gp/product/B004J6DLD4 (it doesn't have to be that model or brand) any will do that has delta v to prevent overcharging and a discharge/refresh mode as all or most batteries periodically need after many partial discharges or storage. Simple chargers work fine, but depending on your usage and doing partial discharging on simple chargers that have timers are not a good idea.. these batteries would last 2-5 years, but with partial discharging with a few full discharged cycles and a smart charger you can probably get more than 5 years out of these batteries (and it's based on usage).
Question:	how long can I store the batteries after charging
Answer:	The charger must be listed to work with the specific chemistry. If your charger says it will charge NiMH (nickel - metal hydride) batteries is should be good. Remove the battery from the charger when fully charged. The battery may be warm when the charge ends; this is normal because of the work (energy transfer) that has been done. In general batteries should be charged at 1/10 their normal discharge rate listed on their specification sheet (usually available online from the manufacturer.) If you are making you own charger, note that newer chemistries such as NiMH require use of an electronic charge management circuit and temperature sensor to vary the charge rate to prevent overheating the battery. (These are available online.)
Question:	Can you charge any brand of rechargeable batteries with this? Or only the brand of batteries that it comes with. Thanks
Answer:	I did not have to charge my batteries the for the first use
Question:	Are EBL's low self discharge rate batteries like Eneloop
Answer:	Yes they are 1.2 rechargeable batteries and they work great+!
