Hello Team,
I have a Motorola 9500 Satellite phone. Haven't used it for months, got it out last night and went to charge both the batteries.
When I put each of them into the phone the display said, "battery inadeq" and neither of them charged.
I can only assume they have both dropped below the recovery voltage for Lithium Ion batteries. (1200mAh)
Anyone actually know whether these batteries can be recovered and by whom or where I'd get at least one without having to sell the house first.

Geoff.

Try your local Battery World - they do re-packs, re-charges etc for just about any battery available. Hope this helps.

Geoff I don't know how true it is but I've heard you can give them a wake up by giving them a touch of double voltage. eg: if they are 6 volt batteries just connect 12volts to them for a second. Someone else may have tried this and knows if it works or not.

Heard the same and have tried it. If they are RS then it's worth the try, it worked for me but in the end they still died. Or the other way is if you have access to a power supply just slowly increase the voltage until you see it accepting current. Might go up quite high but leave it for a little while, making sure it doesn't get to hot. Then back it off to normal charge voltage. Usually though once their dead they are dead.

Geoff.
I have heard this from a mate that has tried it.
Don't laugh till you have tried it yourselves guys. :-)
Wrap the dead battery in a plastic bag (sealed) and put it in the deep freezer for a day or so.
Charge it for the full 16 hours when you take it out and let us know how it goes.
Like I said, I was told that it definitely works for a battery that no longer keeps a good charge.

Thats an old NiCad trick, I never got it to work for me. LiIon are an entirely different beast, when theyre dead theyre dead, that said the freezer is a better solution that the double volts IMHO, a lot safer.

Batteries are in the freezer now and have been for 24hours.
I'll pull one out shortly and stick it on charge to see what happens.
With the incredibly unstable nature of lithium I'm a bit reluctant to hit them with double voltage.
If I feel like a Darwin Award candidacy later in the week I'll give them a go,

Thanks for the suggestions,
Geoff.

Geoff, if you do decide to do the double voltage thing, let me know and I will bring along the camera, at least I can flog the pics and buy you a new battery!

Thanks Bonz, that's real Aussie mateship in action!!
We made need to up the price of the pictures to factor in a battery and a little medical treatment.
Do the Darwin Awards pay for the most novel attempt?

I had factored in the battery costs, and I will make sure I am standing well back so theres no medical costs!

I dont think the Darwin Awards pay anything, its the worldwide recognition and book offers that haul the money in

Sounds like you've got it covered, Thursday afternoon in Newcastle suits me best.
You up for that time frame?
