Charge Cycles



The new National Luna 5-Amp Intelligent Battery Charger uses a smart 8-stage charge algorithm to analyse, charge and maintain all types of 12V lead-acid batteries.

The charger can be used for small batteries, such as those on motor-cycles, quad-bikes, boats and jet-ski’s as well as larger automotive batteries up to 120Ah.

Lead-acid battery types such as wet, flooded, “maintenace free”, calcium, AGM, GEL, EV tractions are supported by the charger. The selectable boost mode can be used to recondition batteries that have been excessively discharged, especially calcium types.

The automatic maintenance mode keeps watch on the battery voltage and makes sure that the battery is topped up without over-charging.

Include with the charger are quick-connect battery clamps as well as fused ring terminals for more permanent installation.
