How to use

Install the battery in a ventilated, dry environment and observe polarity markings when making electrical connections. Use an appropriate charger or charging profile designed for sealed lead-acid AGM batteries to prevent overcharge and prolong service life. For standby applications connect the battery to the host system according to its wiring diagram and ensure the charger or float regulator maintains correct voltage. Periodically inspect the battery housing and terminals for corrosion or damage and keep contacts clean and tight.

Usage recommendations

Store the battery at moderate temperatures and recharge it every few months if kept in long-term storage. Avoid deep discharges whenever possible; follow the equipment manufacturer’s recommendations for depth of discharge and charging parameters. Use protective fuses and proper cabling when connecting the battery to avoid short circuits and ensure safe operation.
