Battery Technology Inc. 07KRV-BTI 4-Cell 15.2V 55WHr laptop battery

Direct replacement for Dell Latitude models

The BTI 07KRV-BTI is a 4-cell lithium-ion battery rated at 15.2 volts and 55 watt-hours. It matches the original part numbers 07KRV, 451-BCWY, 8H6WD, 8P81K, FK0VR, PX0GF, Y86WG and H4PVC. Compatible laptops include Latitude 5330, 5430, 5530, 7330, 7430 and 7530.

Steady output through a full workday

The 55 Whr capacity is designed to sustain typical office workloads without the sharp voltage drop seen in lower-rated packs. Four cells share the load evenly, so runtime remains consistent from the first hour to the last. No sudden shutdowns occur when the charge falls below a critical threshold.

Simple swap with no tools required

The battery slides into the existing bay and locks with the laptop’s built-in latch. Alignment pins prevent incorrect insertion, so the connector seats correctly on the first try. The only common issue is forgetting to fully discharge and recharge the pack once after fitting, which calibrates the fuel gauge. Buyers who need a higher-capacity 6-cell option cannot use this model.
