Replacement battery for HP EliteBook G5

The NShi SS03XL is a new lithium polymer battery rated at 4113 mAh, 11.55 V and 50 Wh. It matches part numbers HSTNN-IB8C and HSTNN-LB8G and fits EliteBook 735, 745, 830 and 840 G5 models. A set of installation tools is included in the package.

Swaps out worn original cells

This unit replaces factory batteries that no longer hold a useful charge or that trigger over-heating safeguards. The jump is worth it when run-time has dropped below a usable threshold or when the original pack shows swelling. Built-in microchip protection guards against over-charging, over-discharging and over-heating to extend the new pack's service life.

Fits inside the existing chassis

The battery occupies the same internal bay as the original, requiring no chassis modification. Installation demands disassembly of the laptop base, so professional fitting is recommended. Before first use, discharge any residual factory charge, then complete three to four full charge cycles to reach full capacity.
