CyberPower OLS1000ERT2U OLS1500ERT2U battery set.
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. Each unit contains a bank of three sealed lead blocks, and this listing includes the complete replacement set you need when the originals begin to fade. The UPS will typically warn you with beeps or a clear display message when the cells reach the end of their useful life, making replacement timing 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 match the factory units: 151mm long, 65mm wide, and 94mm high, ensuring a simple drop-in fit inside the tray. If you prefer a longer backup window, the easy upgrade section lets you select a higher-ampere option for extended runtime while keeping 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. Staying within the UPS’s recommended load prevents thermal stress, helping the replacement set maintain dependable performance throughout its lifespan.
