97 Wh replacement for Latitude E6420 series

This lithium-ion battery delivers 97 Wh at 11.1 V and fits Dell Latitude E5420, E5430, E5520, E5530, E6420, E6430, E6520, E6530, E6440 and E6540 models. It replaces part numbers including PRRRF, M5Y0X, 312-1242, P8TC7, P9TJ0 and R48V3. Buyers needing a different voltage or form factor cannot use this pack.

Thermal and power behaviour

The 7800 mAh lithium-ion chemistry runs at 11.1 V with no active cooling, so it adds negligible heat or noise to the chassis. Normal use draws power only during discharge and charge cycles, matching the original thermal profile. Systems without a compatible charging circuit will not recognise the pack.

Upgrade from lower-capacity packs

Replacing a standard 87 Wh or 4-cell battery with this 97 Wh unit extends runtime on supported Latitude models. The jump is worthwhile when longer unplugged sessions are required and the laptop accepts 9-cell extended packs. Machines limited to 6-cell bays or proprietary connectors cannot accommodate this battery.

Questions about this item

How do I install the 97Wh battery in my Dell Latitude E6420 and what step is often missed?

Power off the laptop, disconnect the AC adapter, slide the release latch, remove the old pack, insert the new 11.1V unit until it clicks, then reconnect power and let the system recognise the 7800 mAh capacity before first use.

What maintenance will the 97Wh pack need and when should I replace it?

Keep the contacts clean, avoid storing the 11.1V Li-ion pack at full or zero charge for long periods, and replace it when runtime drops well below the rated 87 whr level.

What is the first limit I will hit with the 97Wh battery under sustained load?

The 11.1V lithium-ion chemistry limits continuous discharge current, so heavy workloads on a Latitude E6430 will hit thermal or voltage sag limits before the 97Wh capacity is fully used.
