Replacement battery for IBM array cards

This lithium-ion battery replaces part numbers 43W4342 and 46M0855 in IBM M5014, M5015, M5025 and MR10 array cards. It is a new, black unit supplied as a single module. The cell chemistry is Li-ion and the product is manufactured in 2025.

Compatibility limited to listed IBM models

The battery fits only the four IBM array-card models named in the specifications. It will not work in other laptop or server platforms that use different form factors or voltage requirements. Buyers needing a power source for unrelated systems must look elsewhere.

Straightforward swap with correct part match

Installation consists of removing the old module and inserting this replacement in the same slot. The main risk is ordering the wrong part number; verifying 43W4342 or 46M0855 on the original battery avoids that issue. No tools beyond a screwdriver are typically required.

Questions about this item

Which replacement part numbers does this battery cover?

It replaces IBM part numbers 43W4342 and 46M0855, matching the FRU PN shown in the supplier title.

What does the lithium-ion chemistry mean for daily use in an array card?

Lithium-ion cells hold charge longer than older chemistries and need no scheduled cycling, so the array card keeps its cache powered during unexpected shutdowns.

How does the battery connect to the IBM M5014, M5015, M5025 or MR10 array card?

The pack plugs directly into the card's dedicated battery header; no cables or adapters are required.
