Dear Timcredible,
I see nobody is responding to your post - shame...
I also have the same battery but even worse - LB20 - which should be even less powerful then "rat under scalpel"
Recently I dissembled almost new HP 7400 laptop battery to gain eight Samsung 2600 mA/h batteries which would certainly last for long (after charging they show good 4.15V at no-load).
They even have tabs soldered, meaning the soldering would do no harm during rebuilding process, but I really don't know: will the onboard electronics charge normally 2600 capacity whilst designed for 1500 or even less? if it takes just longer, well we can live with that I gues..
Whom could we apply for sound answer (except Black&Decker of cause )?
Anybody?
Thanks!
