FOCUSTEC VI04 14.8V 38Wh 4-cell battery

The FOCUSTEC VI04 is a new lithium-polymer notebook battery rated at 14.8 volts, 38 watt-hours and 2600 milliampere-hours across four cells. It comes in black and is built as a direct replacement for the original HP spare part numbers listed by the manufacturer. Every unit is factory-tested and specified for up to 500 recharge cycles with integrated circuit protection.

Suitable HP ProBook Envy Pavilion models.

This battery fits a wide range of HP ProBook 440 G2 445 G2 450 G2 455 G2, Envy 14T-U 14-U 15-K 15T-K100 17-K M7-K000 M7-K111DX M7-K211DX M7-K200 M7-K010DX and Pavilion 14T-V000 14-V 15-P 17-F series laptops. Buyers whose laptop model or part number does not appear in the manufacturer compatibility list should look for a different battery.

Voltage and capacity define compatibility

The critical specification is the 14.8V 38Wh rating; a battery with a different voltage or capacity will not work correctly in the supported HP systems. Confirm that the original battery shows 14.8V and 38Wh or 2600mAh before ordering.

Questions about this item

Will the VI04 battery fit my HP ProBook 450 G2 without modifications?

Yes, the VI04 is a direct replacement for HP spare 756743-001 and fits the ProBook 440 G2, 445 G2, 450 G2 and 455 G2 series with the original screw holes and latch.

What is the correct way to install the 4-cell lithium-polymer pack, and what step do people often miss?

Power off the laptop, disconnect the AC adapter, slide the old pack out, insert the VI04 until the latch clicks, then charge it to 100% before first use to calibrate the fuel gauge.

How many recharge cycles can I expect from the 38Wh VI04 before capacity drops noticeably?

The manufacturer rates the grade-A cells for up to 500 full cycles; after that the runtime will gradually decrease and a replacement will be needed.
