Discussion

If “tabless” battery technology is new to you, consider reading about Bosch’s new 18V tabless battery, as they provided excellent graphics.

In a nutshell, tabless batteries have a new electrode design and lower internal resistance, delivering more current with less heat.

Every cordless power brand that is launching new tabless-based Li-ion batteries has promised more power, longer runtime, or both.

Ridgid says their new battery delivers 3 more power, and it seems clear via their drilling and cutting application speed examples that the new battery will give least select tools an instant upgrade.

It remains to be seen whether Ridgid will jump onto the pouch cell bandwagon.
