CHARGER SELECTION
How to Choose a 48V Lead-Acid Battery Charger
Battery Capacity
Start with the battery capacity shown on the battery label or product specification and compare it with the available charger configurations.
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.
Connector & Polarity
Confirm the DC connector, polarity and cable requirements before ordering.
