Review: Works great - I used this to maintain the battery on a motorcycle over the winter in temperatures as low a zero degrees Fahrenheit. It was much easier than removing the battery and bringing it in the house to prevent discharging and battery damage over the winter. It was easy to install and versatile. It works with both lithium and lead acid batteries.
Review: Works great! Three year review. - Edit: It's been 3 years since I bought this and it's still going strong. I've used it for mostly AGM battries and never had an issue over the years. I switched to Lifepo4 for my main system this year so this charger has been on 24/7 for the past 8 months (not counting random power outages) keeping my 12v emergency lights, 100Ah battery alive and well. It's a great battery maintainer for standard 100Ah deep cycle AGMs and a solid charger for small lead acid battries. Increasing rating from 4 to 5 stars. Best value for money in my opinion. Oct 2017: Been using it for a couple months and it hasn't failed. When I first fired it up it got really hot while fast charging and I was worried but it has not warped or shown signs of heat damage. It's used almost every day to recharge a small bank off generator power. I was skeptical about buying something with so little reviews but my gamble paid off.

### ⭐⭐⭐⭐⭐ Simple and effecient
*by P***D on March 28, 2019*

When my emergency backup generator didn't start during a recent power outage, I discovered the starter battery was dead, most likely of old age. I purchased and installed a new 12v battery and monitored its voltage. When the generator ran it's weekly 20 minute exercise cycle the voltage would increase to about 13.6v as it was being "charged" by the generator. Overnight (with temperatures dropping near freezing) the voltage dropped under 12, which isn't a good thing for trying to maintain a healthy battery. So I needed to come up with a better solution to keeping the battery topped-off, than the once-a-week boost from the generator. I settled on this unit because of it's variety of battery and charge settings, including ability to charge a lithium-ion battery which I have in my RV, and it's "smart" technology that I've learned is very important after ruining many batteries due to my negligence in maintaining properly. Loved that it came with optional connecting types and 'quick-connect' plug. TIP: set the battery type/charging mode after plugging unit in, but before connecting to battery. Just as the manual explains, the battery voltage reached and remained around 14.3v for a couple days (absorption stage) and has since been holding around 13.4v in the float stage. I may or may not leave the charger plugged in full-time as I monitor how well it will hold a full charge with a once-a-week charge from the generator during the summer when it is hotter and the battery looses less voltage overnight. EDIT (11/21/2025): Charger and battery still working great.
