How to use

Before installation, verify that the battery voltage and capacity match the requirements of your UPS or backup device. Install the battery in a well-ventilated, dry location away from direct heat sources and ignition points. Connect the terminals observing correct polarity and tighten connections to the recommended torque for your equipment. Charge the battery according to the UPS or charger manufacturer’s charging profile; initial charging or conditioning may be required if the battery has been stored. Ensure equipment is compatible with sealed lead-acid batteries and that ventilation and clearance recommendations are maintained.

Usage recommendations

For optimal service life, store and operate the battery at moderate temperatures, avoid deep discharges when possible, and use a compatible charger or UPS with appropriate float and cyclic charge settings. Periodically inspect terminal connections for corrosion and ensure the battery is kept charged during long storage periods to prevent capacity loss.
