Is your old laptop battery not holding a charge anymore?

Here's a replacement: a PH06 battery.

It's compatible with a ton of HP and Compaq models, like the Compaq 320, 420, 620, 625, 621, and ProBook 4320s series.

It replaces a bunch of part numbers including 587706-121, 587706-421, and 593573-001.

This is a 6-cell Lithium-ion battery, with a voltage of 11.1V and a solid 5200mAh capacity.

It's brand new and black.

Quick note: it has the California Prop 65 warning about chemicals, which is standard for pretty much any battery sold in the state.

It's a generic unbranded battery, but it's made to the right specs.

If your old battery is dying, this will give your laptop a new lease on life.
