Good
Battery works good, but this one wasn't the issue with my laptop. It's also a pain to put in.

Works in my Latitude 7390 2-in-1
My Dell Latitude 7390 2-in-1 wouldn't remember the time of day. The light on the front edge blinked white and orange in the pattern which indicated bad CMOS battery. The wires on this replacement battery are longer than on the original, but there was enough room inside the case to route the excess length. Now my Latitude remembers the date and the light on the front edge doesn't blink.

Match to existing polarity.
Easy to install and fits perfectly.

Working with HP Compaq 6910p
After a little online research, it looked like this one would be compatible with my "antique" laptop. The wiring ended up being slightly longer than I needed, but I was able to loop the wiring and tuck it into the routing channel. So far it seems to be working fine! I am glad that I don't have to keep "forgetting to reset" the date and time every time I fire up my old-reliable refurbished retrogaming laptop.

The T60 lives!
Required to libreboot, came in mega handy, The adhesive pad makes life easier because there's no way you're reusing 18 year old tape to reinstall it.

Great customer support
The actual battery I received had the right label on the package, but the battery inside the sealed bag didn't match the label and wasn't the correct battery. So beware that there was at least one mislabeled RomeTech battery in stock at Amazon. On the up-side, RomeTech customer support was awesome - they shipped the correct battery quickly and made it easy to return the incorrect one.
