Only in one review: Voltage 42 V (Modiary MDA238 42V 2A); Test current 1.9 A (Modiary MDA238 42V 2A); Price 16.8 $ (Makita charger).
Makita charger: The charger fully satisfied the author, charges batteries normally, and still works after about 25 cycles.
Modiary MDA238 42V 2A: A well-built charger with auto-shutoff and protection, but it sometimes fails to stop charging after reconnection.
