Review: Performs very well and is user-friendly - Right out of the box is easy/simple to use.
Review: A Great Portable Charger - I was a bit concerned about buying this charger given its relatively low price. But, I am presently surprised. My car has a large battery and a lot of electronics. I had been taking a lot of short trips that I knew were not long enough or high speed enough to charge the battery. Sure enough, it was taking more cranking for the car to start. I didn't want to spend a lot because I don't often charge batteries. So I gave this a shot. It is compact and light, making it easy to carry and even keep in the car. Both the charging and power cables are of good length. I didn't actually measure them, but I would guess they are 4 or 5 feet each. After hooking it up, it immediately and correctly selected the battery type and charge voltage and amperage. It showed the battery was at 30%. It selected the slowest charging speed, which provides the best charging. An AGM battery, which my car has, should charge slow at low amperage. From 30% to fully charged, it took about 10 hours. After the charge, the car started immediately. The charger has an internal fan that came on automatically at some point during the charge and the charger was only moderately warm. Some reviewer, claiming to be an engineer, claimed this is just an old charger with "fluff" claims. Really? I have watched it go through the cycles and checked its output. It does exactly what is says it does. No, it (usually) will not charge a dead battery - something it CLEARLY states in the desertcart description. And, yes, when you buy through desertcart, it handles the returns, which for some reason annoyed that reviewer.

## Questions & Answers

**Q: Will the charger work with batteries connected in parallel (eg. RV house batteries) without having to disconnect them?**
A: This smart battery charger supports charging 12V lead-acid battery. It is not recommended to charge battery in parallel. Because the surge current is too large, the battery would be damaged.

**Q: Why does it say not to charge a dead battery in the warnings? Is that not what it’s meant for?**
A: I have repaired several old, dead but otherwise non-defective batteries. I connect them and select Repair. After a few minutes it will stop and say battery fault however the battery will now should a few volts. I repeat this process until the voltage gets high enough and the repair continues, sometimes for 24 hours. When completed the battery starts my 1976 LC and continues to work well with normal use. Note, as a precaution I always do this outside away from the house. I also know that the battery is not internally damaged.

**Q: Charger says to connect cables when they are connected**
A: This just happened  to me too.  It's because  the charger cannot  recognize  it as a battery. Your battery  is dead dead.  It is a built in safety protocol.   Fortunately  it was my boat battery.  I hooked it up to my car with jumpers for 10 minutes.  I then i hooked up the charger.  The charger  immediately recognized the battery and started  charging.  Hope this helps!

**Q: does this work with optima yellow top battery**
A: Yes. This smart battery charger supports charging all types of 12V lead-acid battery, including AGM, GEL and STD. After searching the optima yellow top battery on market, most of optima yellow top batteries are AGM, which can be charged by this smart battery charger.

### ⭐⭐⭐⭐ Good Battery Charger/Maintainer for batteries WITH Charge. Wont charge a completely dead battery
*by G***0 on September 30, 2019*

Bought this after reading a lot of reviews. Lot of good things about this charger. Bought this because I have a second car I dont get to drive to often and because of that. The battery slowly lost a charge and finally needed to jump start it. Its a good battery but letting it sit caused the battery to die. I got this to help keep the battery charged so I wouldn't have to jump start it every time. I take it out of the box and when I plugged it in it says connect clamps. I do such and it keeps telling me to clamp to the terminals. I undo the clamps, unplug the charger, then redo everything. It gives me the same start message. At first I thought I had a DOA product. But reading into other's reviews. I decided to test it out on a brand new battery I bought a month ago for my daily car. Turns out, it worked as intended when I hooked it up to my new battery. Im a little concern that my it says my battery had a 60% charge but it started to auto charge after awhile. Turns out people are right, This charger works good on batteries that have some charge in it but trying to recharge a battery that has nothing in it doesn't work. So if you're looking to maintain your batteries, it works perfectly fine and as intended. But trying to recharge a completely dead battery doesn't work with this "smart" charger.
