PeleusTech Battery Charger, 12V 14.4V 1A Portable Lead Acid Battery Smart Charger Maintainer - Black

I've charged/maintained a 660 CCA standard wet-cell lead-acid vehicle battery and a Cabela's 55 Ah AGM group 22 marine battery and a group 27 lead-acid marine battery. All were at about 80% state of charge (12.5 volts) when I connected this charger. All fully charged overnight. The voltage with the charger connected to the fully charged battery (charger LED went from red to green) was 13.05 volts. While charging my volt meter showed a high of 14.8 volts. And when left connected to the batteries the charger LED cycled from red to green to red several times. Indicating I presume changing from float to absorb and back.Seems to me this is a good-cheap charger for lightly discharged batteries and also maintaining batteries long term. I'm using mine to maintain the battery in a vehicle a rarely drive and to maintain my AGM marine battery. I'm not going to use this charger to charge batteries down to 50% state of charge, I think at best it would take a very long time to charge them.I'm ordering a second one of these today.

Great little charger! I use it on my car. I do not drive much in winter and the battery gets low. Does it die entirely but does not have enough charge to start my car. I use this charger for a max of 1hr, usually ~10-20 minutes. It charges enough to start my car. I would NOT attempt starting with it connected. I just connect, let it trickle charge, remove, and then start the car. I have not used it for longer than 1hr and in that time it did not get hot at all. Barely even warm to the touch.The connectors are pretty flimsy, thin metal. There is no on/off switch. As soon as it is connected to a battery or the wall its powered up. I connect to battery first, then wall. I unplug from wall before removing from battery. Or clip onto plastic and do one terminal at a time. The unit is pretty dangerous given the lack of on/off. As long as you pay attention, it should not be a problem. Just be aware of that one downfall.

Like other commentors have indicated, this unit came with absolutely no instructions or specifications. This is a problem. I used this unit to charge a 15 amp AGM battery and it appears to have worked. It took about 4 hours which seemed reasonable. When the charging cycle was finished, the red light turned green which I guess signaled the charging cycle was finished. I assumed this because I had no directions or specification sheet to guide me. I would have given this a 5 star rating but for the absent documentation.

Well made. Works well. The leads could be a couple of feet longer.

I like it it works

I've been using these chargers for several years, never lost one, always reliable. I saw one review here, claiming that the charger was bad, when used on a 5 year old battery. The average life span on AGM batteries is 3 to 6 years, leaving me to believe the battery in question has failed.

Cool 😎

I bought this several months ago to keep the battery on my boat charged. I have not had a chance to install it yet. Today, I tried firing up my lawn tractor and the battery died before it started. I plugged this little unit on the battery and hoped tomorrow morning it would be charged. I checked the battery after 6 hours on the charger and it was fully charged. Much faster than I expected. Other comments talk about the flimsy clamps, they are fine for lawn tractor battery posts. Cord length is nice too
