Bosch Officially Announces Their New GBA18V40 CORE18V 4.0 Ah Battery

Last year in October, Bosch ProCORE batteries were spotted in 4.0, 8.0 and 12.0 ah capacities and now Bosch USA has officially announced that they will be releasing their new slimpack 4.0 ah battery under the CORE18V name with a model number GBA18V40 .

Only the name changes from ProCORE to now just simplified as “CORE” or CORE18V while everything else stays the same. It’s a compact 5 cell battery roughly half the size of a comparably equipped 10 cell battery and it uses the latest 21700 cells. Bosch claims that this cell technology brings all of the capability of the original CORE 6.3 Ah battery, but in a smaller package. However expect about 36% less runtime than the 6.3ah Core battery since 4.0 ah is less than 6.3 ah in terms of runtime capacity, since it is a smaller gas tank.

Because it’s housing larger cells I expect it to be slightly larger than the current slimpack 2.0 battery however Bosch assures us that this new battery is 100% compatible with their lithium ion slide pack 18V cordless tools.

Also interesting to note is that Bosch also mentions that they are developing high-power tools to take full advantage of CORE battery technology. This I can’t wait to see! I’m still waiting for their 18V sliding miter saw and 18V table saw they teased us with. Click here to read more about these.

Pricing for the new battery will be $99 in the USA and $129 in Canada.

To be honest, it’s too little too late. I recently switched over to Milwaukee Fuel tools and have been generally impressed with how the little M12 tools generally outperform Bosch’s 18v tools.

I can’t wait to buy their new multi-material cutter (baby angle grinder) as soon as it is available. I had been waiting for the Bosch NAINA version but I expect the Milwaukee version to be available first and outperform the Bosch.
