[Q] T210 driving down new battery to 0.37v

cracker666 · Aug 17, 2014

I have a t210
its totally dead, tried loads of psu, cables, removing the battery and reinserting it.
Holding down keys everything.

I took the plung and bought a new battery.

Its out of the tablet the both batteries read 2.74v on a fluke dvm, inserted in the the tablet they read 0.37v.

wont charge or detect in a pc,
could be failed component, loads of smd components some are diodes etc.
could be usb socket knackered.

What I need is a schem or picture showing diodes or resistors or fuses.

Ebay battety not even registering power now.

You can charged with a one RC model, but with low Ampere.

Offcourse you can try charging a lithium battery with a non lithium charger. But I'll tell you now DON'T!
theres a 80% change it will blow up.
Lithium batterys that are on to low voltage for long are DEAD (as in not living anymore and not able to bring back either).

You need a special lipo charger for this. Ask some of your RC friends or something, as i dont know anyone who still uses NIMH (or NICAD for that matter) anymore.

If you treat your Lithium battery good, it will be good to you too. If you muck around with it its gonna burn you or even poison you with its dangerous vapors.

Have fun with it.
