12 best trickle chargers
A trickle charger, also known as a battery maintainer, is a device used to maintain the charge of a battery over an extended period of time. It is especially useful for vehicles or equipment that are not used regularly, such as motorcycles, classic cars, boats, or lawnmowers. Here are some key points about trickle chargers:
Low Charging Rate: Trickle chargers deliver a low current to the battery, typically between 0.5 to 2 amps. This slow and steady charge helps prevent overcharging and extends the lifespan of the battery.
Prevents Battery Discharge: When a vehicle or equipment is not in use, the battery can slowly discharge over time due to various factors like self-discharge, electronic systems, or small drains. A trickle charger counteracts this by supplying a small amount of current to keep the battery at an optimal level.
Automatic Monitoring: Many modern trickle chargers have built-in microprocessors that monitor the battery's state of charge and adjust the charging rate accordingly.This prevents overcharging and can be left connected for extended periods without harming the battery.
Maintenance Mode: Some trickle chargers have a maintenance or "float" mode. Once the battery is fully charged, the charger switches to a lower voltage to maintain the charge without overloading the battery.
Compatibility: Trickle chargers are versatile and can be used with various types of lead-acid batteries, including standard flooded, AGM (Absorbent Glass Mat), and gel batteries.
Safety Features: Many trickle chargers have safety features like short circuit protection, reverse polarity protection, and spark-proof clamps to ensure safe operation.
Versatility: Trickle chargers can be used for a wide range of applications beyond automotive, such as RVs, ATVs, lawn tractors, snowmobiles, and even some smaller household batteries.
Winter Storage: They are particularly useful for vehicles that are stored during the winter months, as cold temperatures can accelerate battery discharge.
Easy to Use: Trickle chargers are typically user-friendly and come with simple instructions. They often have indicator lights to show the charging status.
Prolongs Battery Life: Regular use of a trickle charger can significantly extend the lifespan of a battery by preventing it from becoming deeply discharged, which can lead to irreversible damage.
It's important to note that while trickle chargers are excellent for long-term battery maintenance, they are not designed for quickly charging a dead or deeply discharged battery. In such cases, a dedicated battery charger or jump starter may be more appropriate.

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: | 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. |

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's the best way to use the repair mode for cars? e.g., use regular way first then switch to repair mode? or start with repair mode directly |
| Answer: | Start with repair mode directly. |
| Question: | Can you please post a link to user manual? Manual did not come in the package as listed. Thanks |
| Answer: | The manual is basically useless. It just says what the charger does vaguely it doesnt get into detail |
| Question: | Can this charger be connected to 2 or 3 batteries and keep them charged at the same time |
| Answer: | Yes it could charge three or four 12V batteries as long as you wire them in parallel. When you wire parallel the voltage stays the same. if you wire in series it doubles. Since this charger will do 24V as well, the other post about charging two 12v batteries in series is also correct and no issue. Keep in mind, the more batteries, the slow you will charge them. This is no different concept than we use with large solar power battery banks. |
