ONEVAN 15000mAh 22500mAh Lithium Ion Battery Rechargeable Battery With Charger Electric Wrench Power Tool For Makita 21V Battery Pin Tool

With extended use, the batteries maintain charge well and the contacts do not get damaged even with intensive use. The main issue is the charger — the supplied charger with 1.2 A capacity is slow and takes up to 8 hours for a full charge. Several buyers therefore obtained their own 2 A charger, which is more practical. The batteries are physically heavier than original Makita batteries, which some view as a sign of quality.

Caveat: The seller states compatibility with Makita 18V tools, but the batteries are actually 21V. Although they physically fit into tools with 18V connectors, the voltage is higher. Nearly all reviews are positive (97.8% five- and four-star), indicating consistent quality without major issues.
