SB03XL replacement battery

This new lithium-ion battery replaces the original SB03XL, SB03046XL, HSTNN-LB4T, HSTNN-I13C and related part numbers in compatible HP EliteBook models. It is built for users who need a direct swap to restore mobile runtime on supported devices. The cell chemistry matches the factory specification for safe operation.

Upgrading from a depleted pack

The jump is worth it when the original battery no longer holds a useful charge or has reached the rated 500 recharge cycles over its life. It replaces OEM part numbers including 716726-421, 716726-1C1 and 717378-001 without requiring a different form factor. Buyers who need a higher-capacity design or a different voltage should look elsewhere.

Straightforward installation

The pack fits the existing battery bay on EliteBook 720 G1, 720 G2, 725 G1, 725 G2 and 820 G1 models using the original latch mechanism. No tools beyond a small screwdriver are typically required. What usually goes wrong is ordering the wrong part number for a specific sub-model, so verify the exact part code before fitting.
