230V Battery Charger for 6/12V Lead Acid Batteries capable of Charging 8 Batteries at a time


The new OptiMate PRO 8 is a highly versatile 6/12V battery-care centre for up to 8 batteries at a time. Compatible with all lead-acid models, GEL, MF-AGM or conventional, the new OptiMate PRO 8 can be used on starter batteries, as well as on industrial, motive or stationary-oriented types.

Just connect up to 8 (even dissimilar) batteries, and these will be individually taken through OptiMate’s widely acclaimed multi-stage programme: desulphation (if necessary), constant current bulk charge, verification, final test & limitless maintenance. Countless connection variations are possible, either enhancing charge current for larger batteries, or handling series-connected blocks, or both. Combinations up to 8A or 96V are possible. State-of-the-art diagnostics, charging, testing and recovery of otherwise “dead” batteries”, all in a single device.
