Very useful a worked fabulous

My son said one of the new batteries only lasted 20 seconds. I knew it had been charged so was surprised. Come to find out the charger light won't turn off. I checked it out with my multimeter and found that the voltage drop exceeds my meter's limit of 1.99v. A functioning battery shouldn't have a drop more than ~0.7v tops. In addition, it won't give more than 7.4v. It may seem strange, but a "7.4" volt battery should charge up to deliver 8.2-8.4v. In short, the battery is defective and useless, so I paid over $20 for one working yet mediocre battery. My only option is to drop both off in town. It doesnt make sense to drive 30 miles to do this, so I've one again been a gullible chump for buying overpriced garbage on Amazon. I could have bought one premium battery from a reputable company for $20 delivered.

So far so good…

Received the batteries I charged them they really do hold to much of a charge but it's deal ableThey do charge fast tho

These are good quality batteries. I had no issues with them and they work really good. I haven’t used the chargers that come with them because I already had one but no issues with the batteries and I would recommend.

Perfect fit long lasting quick charge great product
