Replacement Li-ion battery for Dremel rotary tools

This 10.8 V lithium-ion pack replaces Dremel part numbers B812-01 and B812-02. It delivers 2.5 Ah capacity and 27.00 Wh energy using Panasonic cells. The black housing measures 83.95 x 47.80 x 46.95 mm and ships brand new.

Compatibility and limits

Suits owners of Dremel 8200, 8220 or 8300 models needing a direct drop-in power source. Not for users whose tool requires a different voltage, connector style or higher amp-hour rating. Buyers with non-Dremel brands should verify fitment before purchase.

Deciding specification

The critical figure is the 10.8 V 2500 mAh rating matched to part numbers B812-01 and B812-02. If your tool specifies exactly this voltage and capacity, the pack will work; otherwise it will not.
