Well, I, wdouglass, torturer of lithium polymer batteries, has done it again.
after my successful revival on Christmas day (chronicled in this post Undercharged batteries) I got headstrong. I don’t need to worry about the standby switch, I thought, I can just bring it back from the dead!
Well, last night, i decided to charge up my Pocket Reform, and after sitting on the charger all night, it’s dead as a doornail.
I opened up the bottom of my delightful little laptop, got out my multimeter, and measured 3.5 volts on the right battery. Good so far, i thought. Then i measured the other one – 0.0 volts. seems i’ve murdered it.
Is there a battery i can buy in the united states to replace it? is there a way to revive this battery without burning my house down? I would appreciate any advice, thank you.
One more piece of info, i managed to poke my probes past the built-in safety circuit on the battery pouch and to it’s raw terminals, and measured 2.1 volts, so way out of the happy zone. I also found this on amazon:
it even has a PH connector, which i think is the right one? although those leads don’t really look long enough…
Edit: See the post below this one, the polarity on the cells appears to be reversed, so it’s not a drop-in replacement!
Indeed this cell looks compatible, thanks for highlighting it here. It’s also very good that it has built in protections like the original. As for the cable length, it should be fine. you can put in the battery the other way around so that the cable is closer to the connector.
Thank you for the advice on this last week minute, The new battery (linked above) arrived and has been installed, and my beloved (and neglected) pocket reform is operational once more! One thing i did have to do was to swap the pins on the PA connector, their polarity was reverse of what MNT ships (this is a warning for anyone finding this thread in the future)
