Make sure it fits your 18v tools.
Take a look at this review.

Avoid, does not fit ALL Bosch 18v tools

Bosch makes nice tools, pro to prosumer level but their ecosystem is expensive compared to DeWalt.

Same price I got from Lowe's. Works perfect for my impact and lasts multiple jobs.

Though, I just screw up aluminum track and running wire through house siding.

Normally a 4ah battery would have 10 cells correct? This looks like it has 5. Can somebody clarify if they know?? Thanks!

Bosch and Makita are for the real professionals, Dewalt is ok, Milwaukee is for the wannabes

My 5 year old batteries need to be replaced so I've been looking for a deal to jump on but now I'm wondering if I should wait for the new generation...

The Bosch CORE18V® 4 Ah Advanced Power Battery is a compact battery delivering power in a lightweight solution. It allows you to get the power and lose the weight. The GBA18V40 delivers high power in a compact size for standard to medium-duty applications, such as drilling into concrete, metal and wood; metal grinding; cutting and even light-duty chipping. It delivers 2x the runtime and 60% more power compared to BAT612 18V 2 Ah battery. The GBA18V40 is designed with high-power lithium-ion cells, featuring a single layer of enhanced 21700 cells for greater battery efficiency. Cutting-edge battery design – includes copper end plates, power rails and a flexible circuit board for reduced resistance and increased efficiency. This Advanced Power Battery has Bosch-exclusive CoolPack™ 2.0 technology, which cools the battery faster and helps provide longer lifetime compared to Bosch 18V batteries without CoolPack™ 2.0. This compact battery weighs only 1.10 Lbs. but provides performance comparable to much heavier batteries in a lightweight solution. It is compatible with Bosch 18V tools and chargers and the AMPShare™ System. It also has a high-resolution charge-status indicator.

Bosch are releasing a tabless cell battery pack like everyone else has done (M18 Forge, Dewalt Powerpack, Ryobi Edge 18v, etc)
