How to use

Install the battery according to the equipment manufacturer's instructions and ensure proper electrical connections with compatible terminal types. Charge the battery using a charger or charging circuit designed for 12V sealed lead-acid VRLA batteries, following recommended float and cyclic charge voltages to preserve service life. Avoid deep discharge where possible; return the battery to charge promptly after use. Place the unit in a well-ventilated, dry location inside the device cabinet and secure it to prevent movement or short circuits. Observe polarity and use appropriate protective fusing where required by the host equipment.

Recommendations

For best long-term performance, maintain float charge when the battery is in standby service, avoid exposure to prolonged high temperatures, and follow periodic inspection intervals recommended for standby power systems. Replace the battery when rated capacity falls below the required backup time for your application or if visible damage occurs.
