RefurbUPS CSB 980326CI 12V 18A UPS replacement battery

Compatible UPS Replacement Cartridge

This CSB 980326CI compatible cartridge contains one 12V 18A sealed lead-acid battery designed for high-rate discharge applications. It serves as a direct replacement for UPS units that specify this exact cartridge configuration. The unit ships factory fresh and includes comprehensive installation instructions for straightforward user replacement.

Verify UPS Model Compatibility

Before ordering confirm that your UPS documentation lists the 980326CI cartridge or an equivalent 12V 18A high-rate battery pack. Check the physical dimensions and terminal layout of your existing cartridge against the replacement to ensure proper fit inside the battery compartment. Ensure the UPS firmware or management software does not require a proprietary battery identification chip that this compatible unit may not provide.

Sustained Discharge Behaviour

The high-rate discharge chemistry delivers the rated 18 ampere-hours during the shorter runtime demands typical of UPS backup events rather than during prolonged deep-cycle use. Under continuous load the voltage will decline steadily as the cells deplete and the unit is not rated for repeated full discharges without recharge intervals. Internal resistance remains stable while the battery is within its design temperature range but will rise if the pack is held at elevated ambient temperatures for extended periods.
