TAURKENAM FV993 97WH 11.1V laptop battery for Dell Precision M4600 M4700 M4800 M6600 M6700 M6800

97 Wh replacement for Precision mobile workstations

This lithium-ion battery delivers 97 Wh at 11.1 V and is built to replace Dell part numbers FV993, FJJ4W, T3NT1, PG6RC, N71FM, R7PND and 0TN1K5. It fits Precision M4600, M4700, M4800, M6600, M6700 and M6800 models. A built-in protection board manages charge and discharge cycles for safe operation. The cell pack is rated for more than 500 recharge cycles over its service life.

Capacity and runtime headroom

At 97 Wh the pack provides extended run time for demanding workloads such as CAD rendering or large dataset processing on the supported Precision chassis. Users who regularly push the CPU and discrete GPU will see the battery deplete faster than light office use, so carrying the AC adapter remains advisable for all-day sessions away from mains power. The 11.1 V output matches the original specification, ensuring the system’s power-management firmware reports capacity accurately.

Lithium-ion chemistry limits

Like all lithium-ion packs, capacity gradually diminishes with each cycle and with calendar age even when stored correctly. The rated 500-cycle figure represents a typical threshold before usable capacity drops to roughly 80 % of the original 97 Wh. Deep discharges, prolonged storage at full charge and high ambient temperatures accelerate that ageing process. The pack carries CE, FCC and RoHS certification, confirming compliance with baseline safety and substance-restriction standards.
