12 best battery trickles

Battery trickle charging, also known simply as trickle charging, is a method of charging a battery slowly at a low, constant rate. This technique is commonly used to maintain the charge of a battery over a long period, especially during storage when the battery is not in use. Trickle charging helps prevent the battery from discharging completely, which can lead to sulfation and permanent damage.

Trickle chargers are designed to deliver a small amount of current to the battery continuously. Unlike regular chargers that deliver a higher current to charge the battery quickly, trickle chargers provide a low current, typically around 1-2 amperes, to keep the battery topped up without overcharging it. Overcharging can cause the electrolyte in the battery to evaporate, leading to damage.

Trickle chargers are commonly used for various applications, including maintaining the charge of car batteries, motorcycle batteries, boat batteries, and other deep-cycle batteries used in applications like golf carts and electric vehicles. They are particularly useful in situations where a vehicle or equipment is stored for an extended period and needs to be ready for use at any time.

Trickle chargers are also used in conjunction with jump starters.Jump starters with trickle charging capabilities can not only jump-start a vehicle with a dead battery but also maintain the battery's charge afterward. This ensures that the vehicle's battery remains in good condition even after a jump start.

When using a trickle charger, it's important to follow the manufacturer's instructions to prevent overcharging. Overcharging can lead to excessive heat generation and, in extreme cases, can cause the battery to leak or even explode. Trickle charging is a convenient and effective way to keep batteries healthy and ready for use, especially in situations where the equipment is not used frequently.

User questions & answers

Question: How long are the cords
Answer: There are only two ways to Efficiently & properly charge the unit, plug it into a house 110 V outlet or Or I use a 4000 W inverter in my truck and I plug the inverter primary into the cigarette lighter and the secondary is 110 V which works great on that Max in addition to charging at the same time many charging tool batteries and led work lights. I leave it plugged in My trucks Invertor all the time while driving and all my tools including the max are always charged and hot ready to go.
Question: Just want to make sure I understand this correctly - you can plug this into the cigarette lighter and don't need to connect to the battery
Answer: I wouldn't count on this type of pack for anything with a motor (power tools, the blender, pumps, etc). I tried running a small fridge off a 400 watt inverter connected to a car battery and that wouldn't work. The fridge only needed ~120 watts running, but to start it's motor the "Surge draw" was ~1000 watts that would put the inverter in "overload" alarm every time. So despite the minimal time of running the blender, that "surge draw" is quite often too much for these small inverters.Also FYI, the batteries in these can give you ~200 watts of power for 1 hour (or 100 watts for 2 hours, etc). That's how long they'll last alone. I've seen in manuals that "You can extend the run time by connecting up another battery via the jumper cables", yet if you need multiple parts anyway I'd be tempted to look at a separate battery big enough for everything and a bigger inverter.One of the best suggestions I can make is get something like the "kill-a-watt" meter and see what power your blender & things need for how long. That meter costs $20, so before spending $100+ on this I think knowing what you really need (measuring the power demands) is worth it. That meter can show you both power draw while running (for inverter sizing) and KWH power use (for battery sizing).
Question: how fast does it charge
Answer: I don't have a CPAP or such, but have seen this question posted many times (look under the similar units like Schumacher XP2260 or Duracell 600 packs). This like those other packs has about an "18 amp-hour" battery hinting it can provide 1 amp (at 12V) for 18 hours, or 2 amps for 9 hours, or 3 amps for 6 hours, etc. Many others have said they can get at least 1 night out of the packs if you don't need to run things like a humidifier function or such that needs much more power. Since I don't have the same equipment you do to really know the power use (as well as what settings you need), one of the best ways to find out how long this would last is to get a meter like the "Kill-a-watt" and measure the power use yourself. That meter goes for under $20, so before spending $100+ on this I'd see that as worth it. Based on the info I gave above these packs can provide about 200 watts for 1 hour (or 0.2 KWH). With some of the labels like "400 watt inverter" or such you may think it lasts much longer (like at least 1 hour under that 400 watt load), but it doesn't, so don't expect too much out of it (and that's the same for all packs like this).
Question: What is the float voltage? When the charger indicates it is done charging what is the voltage of the battery
Answer: Yes, you can charge this with many "12V" solar panels that are out there. Just beware that if a solar panels is directly connected up, they can raise the battery voltage to levels over 15V which is considered "Overcharging". So it's best to have a voltage regulator or "Charge controller" between the panel and battery (which will stop charging once the battery is at 14.5V which is "full" for it).

User questions & answers

Question: will this charger work in sub 0 weather ? or a garage thats not heated ? Temp in garage gets in teens at times, and single dig
Answer: The charger is likely all solid state. Temperature shouldn't affect it. The greater problem might be the battery's function at low temperature. A trick, turn on the headlights for a couple minutes, shut them off and try to start the vehicle. The amperage draw will warm up the battery improving its function.
Question: What is the voltage output
Answer: The voltage output varies depending upon where the charger is in its charge cycle and the state of charge of the battery. The maximum voltage I observed was about 14.2 during the charge and about 13.0 during float /maintain. So this charger should be good for use on AGM batteries, which should not be charged at more than 14.5 v.
Question: the red light keeps flashing. If I wiggle the alligator clamps, the red light will stop flashing but in few minutes, flashing occurs again
Answer: According to instructions a flashing red light means it is not charging. I would make sure you have clean battery terminals or check it on another battery you know is good, if it still flashes red it could be a defective charger. Mine only flashes red when it is not hooked up to a battery.
Question: Warning indicates to not attach while the battery is still attached to vehicle. Is anyone using this product while battery is in the vehicle. harm
Answer: I put it on my tractors and other vehicles all the time while batteries are attached. Seems to be just fine for our needs.

User questions & answers

Question: is it support 220v
Answer: My box says: Input 100~240V~1A, 47~63Hz Device says: Input 100-120V~50/60Hz 1A Instructions say: Input AC 100-240V Don’t know what to believe...
Question: Do I need to disconnect my car battery, or can I just add the clamps to the installed battery
Answer: I have it on my generator battery but I am told that you can leave them on a car battery also. I took battery connections apart and put the two rings on the battery. Then its ready to charge at any time.
Question: I have a 92 f350 diesel that has two batteries. Can I hook this up to one side and it will keep both battries charged
Answer: Use a digital multimeter to check continuity between + and + on both batteries, as well as - and -. If batteries have a common + and - node with each other, they are in parallel and this charger will charge both simultaneously. If there is no continuity, there is an internal relay isolating the batteries from each other and you'll have to charge individually.
Question: Can this be used to Jump Start my car
Answer: No way will this help to Jump start a car. If you allow it to charge the battery then let the battery start the car it will have done its' job. When a starter on a car engages the cranking mechanism of the car it draws hundreds (greater than 300 and probably closer to 400) AMPS. The charger cannot supply anywhere near that kind of current. The charger can supply 1000 ma (that's milliamps which = so, .001 amp. X1000 = 1 Amp. To try and start a car with this charger may likely damage it. Hope this helps.
