Is there any discernible difference from the 8Ah other than runtime? Is there an extra row of cells?

The GBA18V120 Profactor Battery has a different contact plate vs. 8.0AH and other standard Bosch 18V Lithium Ion Battery. That is why it is only exclusive with Profactor. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

Will this work with gbh 18v-26f?

No PROFACTOR line only! Will not attach to any other 18Volt tools.

Can they be used on any bosch 18v tool?

No only pro factor toolsCertain Roto Hammer’s the new half-inch impact which is awesome and the 6 inch grinder works great with all of them

Will this fit in the job site speaker?

No! The 12.0 Amp will only fit tools that are PROFACTOR line. This battery will fit any charger, but there is a stop piece on battery that only allows it to insert on Profactor tools. I have fit the 8 amp on speaker and it runs for days on one charge.
