How to empty the battery of Nokia 3210?

Hello,

I've got a very old model of Nokia3210 and it actually still works fine. The
only problem is when the battery runs a bit lower and I make a phone call,
it will be turned off all of a sudden because of low battery. I can turn it
on again, but there is not enough battery left to make phone calls. If I
start to charge it again at this point, the battery will be "fully charged"
in a short period of time, but I can't make too many phone calls out of this
"fully-charged" battery.

I can leave it on and wait and wait and wait to let the battery be used up.
When I charge it at this point, I think the battery is indeed fully charged
because I can then use the phone longer.

So I want to be able to empty the battery myself without just letting it dry
itself up before charging it. But how? What do I need? But of course, if
what I need is rather expensive and doesn't justify itself in terms of cost,
I will just buy another cell phone. But still, just want to know how I can
do it.

Thanks

Herbert

I imagine you could buy a new battery which can't be that expansive. No idea
on how to drain out the battery.

Get a 6V flashlight bulb, pair of wires, connect them to the battery.
When the bulb stops glowing the battery is completely drained.

Most table support chargers have a discharger built in.

The battery is in fact a series of cells all together. Sounds like one or
more of them has died sooner than the others. Basically when you discharge
it, these duff ones empty early and are then reverse charged by the other
cells.

Pulling a low current (on standby) is ok as the voltage loss will go up with
current. As soon as the phone transmits the voltage drops below the point
where the
phone circuits work - hence it turns off.

When you pop the battery on charge, if the phone has
just switched off the duff cell will be holding the voltage
down (as its effectively the wrong way round) but the charger will quickly
'turn it round' , the
voltage jumps up quickly and the charger thinks its
finished.

If you discharge it all very slowly all the cells go flat
in time and then the charger just does its normal
cycle.

Essentially the battery is stuffed. There is one thing you
can try *BEFORE YOU BIN THE BATTERY*

Locate the + and - connectors on the battery - and
using a 12v source *say from a car batteyr charger*
quickly flick 12v on and off the battery a couple of times
whilst it is flat. You might get a spark!

This hideous abuse of the battery is aiming to breakdown
the crystal bridges that have formed inside the duff
cells effectively causing them to self discharge. Tha fact that the other
cells are ok will protect them so long as the current only flows briefly.

But buying new battery is probbaly what is needed here

It sounds as if you have a battery that has lived its useful life and
is pretty much spent if it appears to be full when charged and then
after only minimal use fails. You probably need to spring for a new
battery.

remove NONO from .NONOcom to reply

or when it says it's fully charged, disconnect the charger and reattach - do
it 3 or 4 times - I do the same on my sony camcorder
