AeternaSol 15A Smart Battery Charger, 12V/24V Fully Automatic Trickle Charger & Maintainer, Automotive Batteries Charger with Temperature Compensation for Cars, Trucks, Motorcycles, Lawn Mowers, Boat

Being a new owner of LifPo4 batteries, I purchased a very expensive specialized charger for them. Given I have 3 batteries, I thought it might be a good idea to get this one too. WHAT A PRICE! This one cost a third of what the other charger did and it works just as well. When I got this out of the package, the weight told me it was a quality charger. I had one battery to charge. I read the instructions and followed them. My battery was ready in short order. I should have timed it, but didn't. I am very impressed. I think you will be too.

Hook up gives a complete and full display of the charge process. Digital display is easy to read and understand. No overheating and a quick top up for low battery. A fine addition to anyones auto maintence. Price is excellent for the value of this charger.

This AeternaSol 12/24 volt battery charger is a great tool to have available in a shop collection. It is automatic and has the ability to charge 12 or 24 volt battery systems and can bring many batteries back to useable condition using the repair function. I have used a similar charger to this one and can verify the repair function works on some batteries. The only negative is that it will not charge a completely dead battery. If the charger does not sense any current when connected to the battery it will not turn on.

I can really only review this item on the simple function I bought it for- charging a battery, which it works for very well. I really like all the safety features it has to ensure there's no damage to the battery or the unit. I have yet to use the battery repair mode, but it certainly seems interesting, I'll have to find an old battery to try it out!

Pros: It charges the 12v Car battery as intended. I did not have any dead batteries, but this was able to top off my half charged batteries within an hour so I was please. shows the voltage and charginf amp readings so you can easily monitor the progress. pricing is decent for this item base on local store prices Cons: no real complain other than the cables did get warm probably because of the thin gauge wiring used on the clamps. if this device fails int be future it would be the clamp cables..

This smart charger seems well thought out and easy to use. The display is large and clear, making it simple to monitor charging progress, voltage, and battery status. I like that it automatically adjusts for 12V and 24V batteries and can be used with a variety of vehicles and equipment, including cars, lawn mowers, motorcycles, and boats. The clamps feel sturdy, and the automatic maintenance and safety features provide peace of mind. I haven't tested every mode yet, including the pulse repair feature, but so far it has performed as expected and appears to be a handy charger to have available for maintaining batteries and extending their lifespan. Overall, I'm pleased with it and look forward to using it for routine battery maintenance.

I just got two new Lithium batteries for a portable power station I built and my old charger was strictly for lead acid batteries. This one will do them all. I am looking into the maintainer with pulse repair to ensure that's not a problem for the lithium iron phosphate batteries. I will take off the clamps and add an extended wire with a plug to match the plug on my station. So far, it looks good, works good and taking the batteries to full power. The batteries do have a bluetooth BMS, so I can watch what it does on my phone.

Works great! I needed this for a new lifepo4 battery. it charged from 60 percent to full in under 5 hours. The display it easy to read and works with one mode button.

Great value for a trickle charger and I love the pulse repair feature for batteries that have been sitting for awhile. Automatic adjustment for the ambient temperature makes it hassle free to leave connected to my lawn mower and motorcycle battery.

The charger automatically detects whether it's 12V or 24V battery. When fully charged it auto switches to trickle charge. I was able to repair a highly discharged 12V battery. Highly recommended!
