Review: Just received, impressed, already saved me from a big mistake. - Had a car and ended up replacing with a new battery. The new battery also went dead and I discovered that my trunk light was on and would drain the battery in a couple days sitting. Was going to return the battery I replaced for the $ 10 core charge but bought a battery charger with a repair function and run that on the old battery. Didn't have a load tester and my neighbor was always going to check it but never did. So I ordered this arrived in three days. Checked the battery and the battery was good. Tester said to recharge but the battery only took less than half an hour to charge fully probably because it was already holding its charged. Got a little confused but am impressed that it tests to the battery cca its rated at. Originally wasn't sure whether to set at 1000 or 800 but finally figured out cca means cold cranking amps and set it right. Screen is clear easy to read and the only thing I regret is buying that other charger with repair. This also has repair it pulses a little slower maybe there is a reason but it works somewhat like the other. So for $20 more I now have a good tester and the battery charger combined and don't have to switch. Only drawback I found was that the clamps take some finesse to clamp to a side battery that doesn't have posts but you can get it done. I now have a $ 100 battery I can use in something else rather than a $ 10 core charge so this thing paid for itself in my first try.
Review: Useful thing - A good battery charger. I've never been able to save my battery with the special recovery function, but it charges and discharges perfectly.

### ⭐⭐⭐⭐ Good Product
*by J***. on January 4, 2026*

Recently received this and was able to try it on 3 different batteries. The results for each of the 3 batteries made sense. It has all the features I was after in a single unit. It was very reasonably priced, and I hope it holds up. While the directions overall were very good and clear, except for lack of explanation as to how long the Repair feature takes. I had to Google that and find that it can take 8 hours or more to complete and the unit doesn't give any indication it might take that long.
