FOCUSTEC 4-cell Li-ion 2200mAh 32Wh 14.6V laptop battery

Replacement battery for HP Pavilion notebooks

This 4-cell lithium-ion pack replaces HP part numbers HS03 and HS04 across Pavilion 14, 15, 14g, 15g, 14q and 15q series machines. It matches the original 14.6 V specification and also works with 14.4 V and 14.8 V systems. Grade-A cells and a built-in protection circuit guard against overcharging and overheating. The unit carries UL, CE, FCC and RoHS safety certifications.

32 Wh capacity and everyday headroom

At 2200 mAh and 32 Wh the battery delivers a true charge capacity suited to typical office workloads and web browsing on the supported models. Runtime scales with screen brightness, processor load and background tasks, so heavy multimedia or sustained gaming will exhaust the pack sooner. The smart control system manages discharge to protect cell health over repeated cycles. Users needing all-day autonomy away from mains power should plan for a midday recharge.

Voltage compatibility and form-factor limits

The cell chemistry is fixed at 14.6 V nominal with cross-compatibility for 14.4 V and 14.8 V variants, but the physical pack fits only the listed HP chassis and part numbers. It cannot be used in laptops that require a different voltage, cell count or connector layout. Buyers whose machines fall outside the Pavilion 14/15 series or the quoted spare numbers will need a different battery model.
