12 best ac battery chargers

An AC battery charger is a device used to recharge batteries, typically designed for use with rechargeable batteries found in various applications, including automotive, household electronics, and portable devices.These chargers are designed to convert alternating current (AC) from a wall outlet into direct current (DC) suitable for charging batteries. Here's what you need to know about AC battery chargers:

  1. Types of Batteries: AC battery chargers are designed to charge different types of batteries, including lead-acid batteries (commonly used in cars), lithium-ion batteries (used in smartphones and laptops), nickel-cadmium (NiCd) batteries, and nickel-metal hydride (NiMH) batteries. Each type of battery may require a specific charger designed to match its characteristics.

  2. Voltage and Current: AC battery chargers provide a specific voltage and current output, and it's crucial to use a charger that matches the specifications of the battery you are charging. Overcharging or using the wrong charger can damage the battery or pose safety risks.

  3. Charging Modes: Some AC battery chargers offer multiple charging modes, such as regular charging, fast charging, and trickle charging. Fast charging delivers a higher current for a quicker charge, while trickle charging provides a slow, steady charge to maintain battery health.

  4. Safety Features: Many modern AC battery chargers include safety features like overcharge protection, short-circuit protection, and reverse polarity protection to prevent accidents and battery damage.

  5. Automatic vs. Manual: Some chargers have built-in microprocessors that can automatically detect the battery type and adjust the charging parameters accordingly. Manual chargers, on the other hand, require the user to set the charging voltage and current.

  6. Multi-Bay Chargers: For users with multiple batteries to charge, multi-bay chargers are available, allowing you to charge multiple batteries simultaneously.

  7. Automotive Battery Chargers: AC battery chargers designed for automotive use are often called "car battery chargers" or "jump starters." They are used to recharge or jump-start vehicle batteries, providing the necessary power to start a car that has a dead or low battery.

  8. Maintenance Charging: Some AC battery chargers are designed for long-term battery maintenance. These chargers deliver a low, constant charge to keep batteries at their optimal voltage levels during storage.

  9. Portability: Portable AC battery chargers are available for on-the-go use, often used for charging smaller batteries like those in smartphones, cameras, or power tools.

When using an AC battery charger, always follow the manufacturer's instructions and ensure that the charger is compatible with the type and size of the battery you are charging. Proper charging practices help extend the life of rechargeable batteries and ensure their safe and efficient operation.

User questions & answers

Question: Does it develope a memory effect if charged before total drainage
Answer: I cannot tell. I have had one for a year and it holds the charge very well, so it has only been fully charged twice.
Question: Will this charge batteries on an rv overnite so i dont have to continuously run generator while camping
Answer: No, not even close. The Halo Bolt simply does not have the battery capacity to charge a large 12V deep cycle battery. Let's compare its capacity to just 1 deep cycle 100 amp hour (Ah) battery. The Halo Bolt has a capacity of 58.8 watt hours (Wh), equivalent to 4.9 amp hours (Ah) @ 12V. Basically the 100 Ah deep cycle battery has 20.4 times the capacity of the Halo Bolt. You could look into solar options. YouTube channel "DIY Solar with Will Prowse" is a good resource. If you are looking for an all in one solution, you could consider the "MaxOak Bluetti Power Station 2400 Wh/1000W Inverter" for $2,000 on Amazon. It is very large and weighs 48 lbs. It can run a 200 watt device for 10.2 hours. There are also many other smaller options on Amazon. You could also get an inverter generator instead of a typical generator. Inverter generators are more efficient and run quieter. Hope all this helps.
Question: how long will this run a 55 watt max fan for
Answer: The Halo bolt has a capacity of 58.8 watt hours (Wh). The 115V AC inverter would have an efficiency of around 80%. Your device requires 55 watts to run. Therefore (58.8 Wh * .80) / 55 watt device = 0.86 hours, or 51 minutes of runtime. Not a lot of runtime. You could consider a much larger power station (aka solar generator). For example I own a Honda/Jackery 290 power station. It has 292 watt hours (Wh) of capacity, and a 200 watt pure sine wave AC inverter outlet. This is basically 5 times the battery capacity of the Halo Bolt. Though it does weigh 6.6 lbs and costs $300 on Amazon. Also it is not TSA compliant, nor does it jump start cars. Let's plug in the numbers for the Honda/Jackery 290 with 292 Wh of capacity. Its pure sine wave AC inverter would be around 85% efficient. Basically (292 Wh * .85) / 55 watt device = 4.5 hours of runtime. Hope this helps.
Question: Is this TSA approved in carry-on bags
Answer: If you look at the current TSA guidelines (the Halo website has a link) batteries less than 100 watt hours may be taken in carry-on luggage and batteries 101-160 watt hours require airline approval. (Lithium batteries may NOT be taken in checked luggage.) This unit is clearly labeled on the box as well as the back of the unit as 58830 mWH. To convert milliwatt hours (mWH) to watt hours simply divide by 1000 (for example: 58830 mWH/1000 = 58.830 watt hours. This unit is just under 59 watt hours and is well under the limit for requiring airline approval. It's possible that someone in TSA might not know the regulations (or how to convert mWH to watt hours) in which case you might need to politely educate them. I'm guessing though that these have been around long enough now that they already know.

User questions & answers

Question: When using the 12 volt setting, what are the amps
Answer: I haven't used or tested the 12 Volt setting. However excluding losses a IxV=W, so we can substitute and get I=W/V which in this case would be I=12/12, so theoretically the maximum current at 12 Volts would be 1 Amp.
Question: I have no idea what "inner positive" means, so how does one know if they have a device that is inner positive? all the connection says is 4.5v dc
Answer: This can be tricky in some instance.. This unit has a (+) positive inner, and a (-) negative outside. Which means the female of the plug is positive, and the male ( outer metal) is negative. Now tricky part, some devices use outer ( positive "+") and (negative" -" ) inner. I ran into this with some light, and score board. I bought generic transformer on Amazon, and none worked. took apart light , and found the polarity was reversed. This is how OEM folks fool conservatives that don't buy OEM parts, or know how electricity works in dc circuits. (Had me confused for an hour or two) OEM= Original Equipment Mfg.
Question: i am looking for an adapter which would output 12v at .5A. Can this adapter do that
Answer: Hello Leno,Yes, it can. FYA, find a suitable adapter plugs for your device.Hope this helps you, have a nice day!
Question: I have a 4 ft Gemmy indoor inflatable football player that needs a 12 watt charger. Anyone know if this will work
Answer: Not 100% sure. List three points to help you distinguish if it's compatible...1.Polarity: inner positive2.Meet the working requirement of 12W charger, be aware that the maximum current is 1.2Amps. (If needed current exceeded 1.2A, please search: SoulBay 30W Charger.)3.Find the suitable adapter plug,6 Connection Tips Spec.: 2.5*0.7mm, 3.0*1.1mm, 3.5*1.35mm, 4.0*1.7mm, 5.0*2.1mm, 5.5*2.5mmBesides, Should you have the detailed sticker of your original adapter, please keep free to contact us at [email protected] this helps you and best wishes!

Question: Will this charge a 48V lithium iron phosphate
Answer: No. The output is selectable to be 12 or 24 VDC.
Question: i have 4 200ah agm batteries in parallel, what should i set the current control knob to
Answer: Amps should not exceed 1/4 of the total battery pack amp hour rating so you should be able to use it at max power
Question: Se le puede aplicar carga a un banco de baterias
Answer: Yes. This can charge a 12 volt DC or 24 volt DC battery bank.
Question: How many watts does this consume at 75 amps? Using a 2000 watt Honda generator as the power source
Answer: What you won't find in the specs is this has power factor correction. I am getting the lowest of 0.94 which is very important when trying to run a converter off of a generator. Unlike regular switching pwoer supplies, that have a power factor of 0.72 and require 1300 watts for ~800 watts output, this does not. A 2000 watt generator will more than handle this charger at 100% (75 amps)
