Replacement battery for IBM AS400 iSeries 2757

This nickel-zinc battery replaces the original IBM 53P0941 unit in the AS400 iSeries 2757 RAID controller. It delivers 3400mAh at 3.7V for 12.58Wh of capacity. The pack measures 78.43 x 52.70 x 11.81mm and weighs 79.4g. A decoded chip ensures the controller recognises it as the original part.

Practical limits of nickel-zinc chemistry

Nickel-zinc cells operate at 3.7V and require 2 or 3 full charge and discharge cycles to reach peak runtime. The supplier cautions against storage above 60°C and warns that low-quality third-party chargers will shorten service life. Disassembly, fire and water exposure are prohibited. No figures for maximum charge current, cycle life or self-discharge rate are supplied.

Build quality and connector implications

The battery is built to the original specifications and tested for overcharge, over-discharge, over-voltage and short-circuit protection. Shock-absorbing foam in the package protects the pack during transit. Installation videos are referenced online, indicating a user-replaceable connector design. The unit carries ISO9001, RoHS and CE markings. Buyers who need a higher-capacity chemistry or a different form factor cannot use this pack.

Questions about this item

Which part number confirms this battery fits my IBM AS400 iSeries 2757 RAID controller?

The battery replaces IBM part number 53P0941 and is built for the AS400 iSeries 2757 RAID controller, so matching that part number ensures compatibility.

What runtime can I expect from the 3400mAh capacity once the battery is installed in the RAID controller?

The 3400mAh cell at 3.7V stores 12.58Wh, which typically maintains the RAID cache for several hours during a power loss, depending on the controller load.

Does the nickel-zinc chemistry work with the standard charging circuit in the 2757 controller?

Yes, the pack includes a fully decoded chip that communicates with the original charging circuit, so the nickel-zinc cells charge correctly without modification.
