Direct Replacement Battery

The Estry 1500mAh 3.7V lithium cell matches the original Li3717T42P3h654458 specifications for Authentic MF63 EUFI890 U790 devices. It delivers 5.55Wh capacity in a single pack format. Overcharge, over discharge, over voltage and short circuit protection are integrated for safe operation.

Compact Protected Cell

At 64.83 x 43.97 x 5.5mm and 57.0g the battery fits the original compartment without modification. RoHS, CE, ISO9001, UN38.3 and MSDS certifications confirm compliant materials and transport safety. The flat lithium pouch design suits slim power tool housings where bulky alternatives cannot be used.

Upgrade From Depleted Packs
