CyberPower OLS1000ERT2U OLS1500ERT2U battery for UPS.
Full set of three replacement batteries for the CyberPower OLS1000ERT2U and OLS1500ERT2U, high-quality UPS compatible battery pack with upgrade options.
The CyberPower OLS1000ERT2U and OLS1500ERT2U are rack-mount online double-conversion UPS units designed to provide clean, conditioned power for equipment that needs stable protection. Inside each machine sits a bank of three sealed lead blocks, and this listing offers the complete replacement set required when the originals begin to fade. The UPS will typically warn you with beeps or a clear message on the display when the cells have reached the end of their useful life, making the timing of a replacement straightforward.
Each battery in this pack is a 12-volt AGM sealed lead unit rated at 7Ah on the 20-hour curve, fitted with T2 spade terminals for an easy swap. Dimensions are identical to the factory units at 151mm in length, 65mm in width and 94mm in height, ensuring a simple drop-in fit inside the tray. If you prefer a longer backup window, the easy upgrade section allows you to select a higher-ampere option that offers extended runtime while retaining the same physical size.

Keeping the new pack healthy starts with storing the UPS in a cool, well-ventilated location and avoiding hot, enclosed spaces that trap heat. Letting the system complete its scheduled self-tests helps keep the three blocks balanced, and allowing a full recharge after deeper discharges preserves long-term capacity.
