CHARGER SELECTION

How to Choose a 48V Lead-Acid Battery Charger

01

Battery Capacity

Start with the battery capacity shown on the battery label or product specification and compare it with the available charger configurations.

02

Permitted Charging Current

Confirm the charging-current limit specified by the battery manufacturer before selecting the charger. A higher current should not be chosen only for faster charging.

03

Connector & Polarity

Confirm the DC connector, polarity and cable requirements before ordering.
