Replacement battery for Dell Inspiron and Vostro

The Dr. Battery MPL05308P-21 is a new lithium polymer unit rated at 11.4V and 3400 mAh. It is built for owners of compatible Dell Inspiron and Vostro laptops who need a direct replacement for an ageing or failed original pack. The black cell assembly matches the OEM form factor and includes an integrated smart control chip.

Fit and installation requirements

The battery slots into the existing bay without adapters or cable changes, so the laptop chassis and connector stay untouched. It frees the user from relying on mains power once the original cell no longer holds a usable charge. Compatibility covers a wide range of Inspiron 13, 14, 15 and 17 models plus Vostro 14 5468, but the part number must match the original.

Upgrade context and limits

This unit replaces Dell part numbers such as CYMGM, FC92N, FW8KR, P26T, P32E, P58F, P61F and P62F series cells. The jump is worth it when the original pack drops below useful runtime or shows swelling. It does not add capacity beyond the 3400 mAh rating, so buyers who need longer unplugged time than the stock design allows will not gain extra hours.

Questions about this item

How long does the 3400 mAh capacity last under continuous load before the battery reaches its limit?

The 3400 mAh lithium polymer cell delivers up to 42 Wh of energy, and runtime depends on the laptop's power draw; higher loads deplete the charge faster.

Does the battery get hot or noisy during all-day operation?

The pack has no moving parts and includes overheat protection, so it runs silently; temperature rise varies with the laptop's thermal design and workload.

Which original Dell part numbers must the user already have to confirm compatibility?

Compatible replacements include CYMGM, FC92N, FW8KR, P26T, P26T001, P26T002, P26T003, P26T004, P32E001, P32E002, P58F, P58F001, P61F, P62F and P62F001.
