The WA3742 is a single-slot charger for select 20V lithium-ion packs, including the WA3520, WA3525, WA3578 and WA3580. It runs on 100-240V input and charges at 20V/0.4A, with a flashing green LED during charging and a solid green light when done. A full charge takes roughly 3 hours depending on the pack. It suits owners of these 20V packs who need a spare or replacement charger, but the 0.4A output is slow next to higher-current chargers and it charges only one battery at a time.

The WA3742 is a single-slot charger for select 20V lithium-ion battery packs, including the WA3520, WA3525, WA3578 and WA3580. It charges one compatible battery at a time. It has a two-prong US plug for indoor wall outlets.
It accepts 100-240V AC, 50/60Hz input and provides 20V DC, 0.4A output. An LED indicator shows charging status: the green light flashes while charging and stays solid green when the cycle is complete. Charging takes approximately 3 hours, depending on battery capacity, condition, temperature and remaining charge.
Before use, confirm the complete battery model number. Compare the battery rails, electrical contacts, charging interface and voltage with the product images and specifications. Voltage alone does not make a battery compatible, since the battery interface and charging electronics must also match. To charge, seat the battery fully in the slot, then plug the charger into a wall outlet. Unplug the charger before removing the battery.
