Review on Battery Replacement: HP Spare 776622-001 (LA03) for HP 15-f272wm and 15-f222wm by Alexander Craner

There are two different batteries that have very similar names:776622-001 (LA03) this has 11.1 V and 31 WH776622-001 (LA04) this has 14.8 V and roughly 38 WH(Choosing the wrong one could cause your laptop to fail)The easiest way to figure out which one you need is to look at you're battery and find the voltage and Wh.A slight issue with this battery is that it's not the exact same size as the original battery. It extrudes a little on the bottom of the laptop, and a bit in the back. It's a tighter fit, but it still fits with a bit of persuasion. So far this one seems to be working pretty well. It will probably give you about 2 hours on a full charge, maybe a bit more.Also be wary of the 5 stars on this product, they send out a card that says they will give an additional 12-month warranty if you rate 5 stars.
