Rechargeable Sealed Lead Acid (VRLA) 12V household battery RAYOVAC ACC-BAT-4AH
RAYOVAC ACC-BAT-4AH is a rechargeable sealed lead acid (VRLA) household battery with a nominal voltage of 12 V and a capacity of 4.5 Ah. Designed for indoor standby power applications, this maintenance-free battery offers leak-resistant construction and stable 12 V DC output suitable for alarm systems, emergency lighting, small uninterruptible power supplies (UPS) and other low-to-medium drain devices where reliable backup power is required.
The VRLA design provides a sealed, maintenance-free battery that does not require water top-ups and minimizes the risk of acid leakage. Its rechargeable chemistry supports repeated charge and discharge cycles for long service life when used according to manufacturer charging guidelines. Compact dimensions and standardized 12 V output make it compatible with a wide range of household backup systems. The battery is intended for indoor use and offers stable performance in typical ambient conditions for residential and light commercial installations.
Before installation, ensure the battery voltage and terminal orientation match the device specifications. Install the battery in a dry, well-ventilated indoor location away from direct heat sources and open flames. Connect the correct polarity leads and secure terminals to prevent accidental disconnection. Use a compatible charger or charging circuit designed for 12 V VRLA batteries and follow recommended charge voltages and current limits to avoid overcharging. For backup systems, verify charging status periodically and perform functional tests of the connected equipment to confirm the battery provides the expected runtime.
Store and operate the battery at moderate ambient temperatures to maximize service life. Avoid deep discharges whenever possible; recharge the battery promptly after use. Replace the battery when capacity drops significantly or when it fails to hold adequate charge for the intended backup duration. Recycle or dispose of the battery according to local regulations for lead-acid batteries.
