14 best small battery chargers

A small battery charger, particularly in the context of automotive use, is a portable device used to charge and maintain the charge of vehicle batteries. Here's what you need to know about small battery chargers:

  1. Portability and Compact Size:

    • Small battery chargers are designed to be portable and easy to carry. They are compact in size, making them convenient to store in your vehicle or carry in a toolkit.
  2. Battery Compatibility:

    • These chargers are typically compatible with a range of batteries commonly found in vehicles, such as lead-acid batteries (including AGM and gel cell types).
  3. Charging Capacity:

    • Small battery chargers are suitable for charging batteries with a lower capacity, often found in motorcycles, cars, boats, or other smaller vehicles.
  4. Charging Process:

    • They employ a multi-step charging process, including stages like bulk charging, absorption, and float/maintenance mode. This ensures a proper and safe charge for the battery.
  5. Voltage and Amperage:

    • These chargers typically operate at common voltages (e.g., 12V) and have adjustable amperage settings to suit different battery sizes and conditions.
  6. Safety Features:

    • Small battery chargers often include safety features like reverse polarity protection, short-circuit protection, and overload protection to prevent damage to the charger and the vehicle.
  7. User-Friendly Design:

    • They usually have user-friendly interfaces, LED indicators, and simple controls for easy operation.
  8. Versatility:

    • Some small battery chargers also function as jump starters, allowing you to jump-start a vehicle with a dead battery.
  9. Maintenance Charging:

    • Many small chargers have a maintenance or float mode, allowing them to be connected to a battery for an extended period without overcharging, thus keeping the battery at an optimal level.
  10. Application:

    • Small battery chargers are ideal for intermittent or occasional use, such as for keeping a vehicle's battery charged during periods of inactivity or for emergency situations.
  11. Charging Speed:

    • Due to their compact size and lower charging capacity, they may have a slightly longer charging time compared to larger, more powerful chargers.

When choosing a small battery charger, consider your specific needs, the type of vehicle you have, and the capacity of the battery. It's important to follow the manufacturer's instructions and safety guidelines when using any battery charger.

User questions & answers

Question: Why is it not recommended to keep a trickle charger hooked up all the time
Answer: beats me. i keep mine hooked up from 12/31 to 4/1 and only then do i take it off. my understanding is that you do not need to disconnect it-it powers down on its own, but you mught want to find the user nistructions and check me on that. good product if youre not in a hurry
Question: how fast does it work
Answer: if your battery is low it may take up to 3 0r 4 days since it's a low amp charge and designed to keep the battery at full charge once it's at full charge. This charger is super for use when you don't drive the vehicle a lot and it sits for any length. it can be used on the battery in the car or taken out, once it's on it can stay plugged in all winter of summer just unplug it when you go driving. If the car stays outside they make a waterproof model. If your looking for a fast charger this is not what you want, if you do buy this make sure it's the 12 volt model ... hope this will help you
Question: Why is this not available in California
Answer: Charge for free! Buy a low wattage solar battery charger/maintainer at Harbor Freight instead because it works very well maintaining the battery charge provided that the battery is fully charged before hooking up this solar charger.... it will only maintain the charge. Not made to fully charge a discharged battery. Point the solar panel southwest to get the most out of the sunlight during daytime. I have used this $9.99 if on sale gadget for years now on my boat and car and has not failed me yet. It comes with all the hook up accessories needed. I have not used the boat for 2.5 years at a time and the gel battery is as good as when I installed it 7 years ago. My car wet cell battery also is as good as when I first installed it and I only use the car abroad every 12 months when I am in town for 3 weeks. Car or Boat batteries Gel or not will not last it's lifetime if it is always discharged and recharged. Maintaining the charge is key to it's longevity. Good luck! No need to blame anybody. The State of California is an environmentally conscious state and that is a good thing for everybody.
Question: Can this be used to charge an AGM battery
Answer: Stupid me, but don't all lead acid batteries use the same chemistry? I've read only that 6-cell lead-acid batteries should never use a charging voltage exceeding 14.4 volts, since water will begin to H2 gas and O2 gas above that. You risk explosion and loss of electrolyte beyond that. Explain why this is different for AGM, Flooded, and Gel batteries!

User questions & answers

Question: What does flashing green lights mean
Answer: I get the flashing lights when I first plug in my drained batteries. It could mean that a charge is in progress. I get a solid light after the charging is completed.
Question: Can I connect this to a 5v 2.4a wall charger
Answer: 5v is the standard for USB ports, and the device will try to draw whatever amperage it needs. The picture of the Overnight charger says it needs only 1.0 amps, while the Rapid variant's picture says it requires 2.1 amps, probably for the more juice it's shoving into the batteries. So yes, a 2.4 amp wall plug will easily handle either one.
Question: Does it come with AA/AAA batteries
Answer: No
Question: Will this work for the zhiyun crane 2 batteries
Answer: My understanding after reading the manual is that any rechargeable NiMH (Nickel-metal hydride battery) can be used..Hope this helps😊

User questions & answers

Question: is this charger made in the USA
Answer: No, China. I searched for a charger made in USA, but no luck finding one.
Question: I just bought these with your charger and the batteries heat up so much that i cant touch them. Is that normal
Answer: They will get warm, but not to the point where you cannot touch them. Are you using the EBL charger? That thing is a piece of crap. I bought one from Interstate Batteries, and haven't had a problem. The EBL charger kept telling me that the batteries (EBL as well) were not charging due to an error.
Question: Should the batteries be charged prior to first use
Answer: Being in the mobile DJ business, I never trust pre-charged batteries. I always charge them when initially received. All batteries had various levels of charge, yet none were 100% charged.
Question: Are these Low Self Discharge
Answer: In my experience with NiCad batteries, they should be fully discharged, before recharging them. NiCad batteries exhibit a "memory" https://www.google.com/search?q=NiCd+battery+charge+and+discharge+memory&ie=UTF-8

User questions & answers

Question: Can this charge 2 D batteries at once
Answer: I found a trick online that RESTORED ALL MY BATTERIES. It looks like magic but it worked for me on 8 batteries. You can google it and find the videos. Basically: find two short wires. Connect a bad battery with a good battery for 3-4 seconds (male to male, female to female). This will resurrect the bad battery but drain the good one. Now charge them both. Again, this trick salvaged 8 batteries I already put for recycling.
Question: Will this charge lir123a batteries
Answer: You don't need to charge in pairs, you can charge one battery.
Question: Will this charge 6 D batteries at the same time
Answer: Mine is more than 24hrs but its still on one bar of charging my C batteries😤
Question: Will this charge all types of batteries (not just ebl
Answer: I cannot get this device to charge EBL 9V NiMH batteries. I tried 2 of them and the red light inside the charger lights up, but no charging, no voltage occurs. This is an EBL charger and EBL batteries! The charger will charge other EBL batteries like AAAs and AAs. Is it defective?
