Works Great; Good Price.
Working great. Saved a lot of money compared to Bosch branded.

Reliable battery so far
I have been using since I purchased & can only say that it is working as hoped. I plan to purchase another for backup soon.
User
Better for the price.
Fits my Bosch tools and charger. Better than I thought it would be.
User
A perfect replacement at a fraction of the cost
These batteries are a 1for1 replacement of Bosch batteries. Seem a bit heavier but work fine. Given lithium battery reputation for causing fires, I can’t stop wondering what’s the real internal difference with Bosch so I’m being cautious till I get real experience with them.

Work great, I would recommend
I'm using this on a drill and impact driver. No problems. Battery life seems a bit better than the oem 2Ah battery I replaced. Keep in mind this battery is roughly 3/4 inch taller than the 2 Ah bosch battery so if you're needing to work in a really tight spot it could be a problem.

Bad battery
The battery charges but does not fit the tool correctly. It randomly runs sometime
User
Extra power when you need it.
Always good to have a spare battery when the job is a long one. Perfect replacement.
User
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.

Hasta ahora bien
Pues no lo he usado así como en alta demanda ya que soy mas de "hobbie" con las herramientas pero no noto mucha diferencia con las ProCore de Bosch en herramientas básicas, me faltaría probar en herramientas PROFACTOR pero obvio no se van a comprar con una de 8ah
