As a replacement to a factory Bosch battery, this has been working incredibly well. Lasts a very long time!

Product not the same as advertised. They don't appear as rugged looking with no red grid on the bottom. They do fit and I hope they preform well.

Quickly charged on my charger, long battery life. The price for two of these was much cheaper than the Original Bosch single battery. Am very happy to have for back up battery power.. They arrived when promised, with quick delivery.

Husband loves them. They work on his Bosch drills perfect

One battery only lasted a few weeks before it would no longer work. The other doesn't fit correctly in the tool so I am constantly wiggling it to get power. Both of them last about the same as a 2AH battery at best. Definably not as advertised, spend a little more for one good battery and stay away from these.

I bought different batteries different prices and in the end all batteries are from the same manufacturer

When the original battery for my cordless drill stopped charging, I was sort of shocked by how much the branded replacement cost- so I did some searching and came across these. I *think* I got both of them for the price of ONE of the manufacturer's replacement (or darned close, anyway). I have been using the drill most every weekend for months now, and they work just fine. They charge just as quickly as the original on the original charger, plus, the charge seems to last a bit longer than the battery that came with the drill- and I always have a spare, so I don't have to take a break while waiting for the battery to charge.

Very good quality
