Battery 6550B 6455B TD06 TD09 Compatible with HP EliteBook ProBook Compaq 6730B 6735B 6530B, fits P/N 482962-001 HSTNN-UB69 KU531AA 6-Cell 5200mAh/58Wh 11.1V

I took it out of the packing box, slipped it into the battery slot of my old laptop and it works like a charm. Beats the price of a new machine with Windows 10, and it helps me beat Microsoft's planned obsolescence -- I will continue to run my rickety old mule with its Windows 7 system.

the battery doesn't carry that much snap to its punch, ie. the amp capacity is low, but it is just I needed for a laptop that stays home and usually plugged in.

Only lasted one year and then would not take a charge.

Keeps about a 5 hour charge on my laptop.

on day 1 it worked fine but fast foward 3 months and the battery last 5 min then just dies. not worth the price tag

I've use it for my brother's HP Probook 6550b and it works fine, definitely better than its old battery because the old one was big and mid battery was out of the laptop, and this one fits perfectly.

Might last an hour off the charger. OEM battery was well over 2 hours. I did follow the instructions.

So far so good. My laptop use to shut off and would say I needed a new battery. So I bought this. Hasn’t shut off as yet lol
