Damaite M5Y0X 97Wh 9-cell laptop battery

Damaite M5Y0X 97 Wh 9-cell replacement battery

This 11.1 V lithium-ion pack delivers 97 Wh from nine cells, matching the original Dell part numbers listed for Latitude E6440, E5430, E5520, E5530, E6420, E6430, E6540 and Precision M2800 models. It is built for owners of those Dell laptops who need a direct-capacity swap without changing form factor.

Black 9-cell pack with listed Dell part-number

The unit replaces Dell part numbers including T54FJ, 8858X, 7FJ92, 04NW9, 2P2MJ, NHXVW, 4YRJH, UJ499, N3X1D, 71R31, P8TC7, 911MDS, P15G, P15F, P16G, X57F1, PRRRF, XV2VV, 451-11704, 312-1325, 312-1324, 312-1163, 312-1311, 312-1242, 312-1164, 312-1323, 312-1310, CWVXW, DHT0W, HCJWT, 8P3YX, M1Y7N, P9TJ0, RU485, YKF0M, R48V3 and 451-11947, so buyers can verify compatibility against their service tag before ordering.

Simple bay swap with no tools beyond a latch release

Installation consists of powering down, sliding the battery latch and inserting the pack until it clicks; the shape matches the original bay on Latitude E-series, Vostro 3460, 3560 and 14R, 15R, 17R series chassis. Users who skip the full charge-discharge cycle on first use may see inaccurate runtime estimates until the firmware recalibrates.
