Looks like its the original battery, just no Bosch on the side!

Why did you pick this product vs others?:So far I am very impressed. Retail on the battery with 2 AH, which is their running time is $80.00 everywhere. This battery with 4 AH was $35.00 Granted it is not a Bosch battery, but it fits my tools, goes in the charger and works like my other OEM batteries. I needed a new battery and the cost for an OEM was just too much. If I have any problems with this battery I will update my post.

good value for the money.

Purchased this battery to replace an OEM battery that got its tabs damaged. charged right up and works great. Haven't used it to its full potential yet since I've been busy with other projects that don't require my drill. I would def buy again.
