Yes, it works. A mate of mine who has a 'phone shop in Phalaborwa
revives 'phone batteries by kick staring them using a car battery as
crude power pack!.

Some people may have done that before, - but just in case, - I thought
I'd share this tip.
I remember that some people on the list were using La Crosse ("smart")
charger for AA and AAA batteries. (I bought it originally for the
flash light, primarily, but then used for all other needs.)
I have the older model, the blue one, I believe BC-700, but from what
I've read, - all their models suffer from one problem:
When the battery is depleted so that its voltage is below some
threshold (I believe, it is 0.5 V), the charger displays "null", and
refuses to charge that battery.
The workaround I've found is to use a cheaper charger (I have a
Duracell-branded "fast charger") - to "jump-start" that battery.
So, you insert your batteries (whatever quantity is needed in that
charger, in my case, - it takes batteries by pairs), including
the "faulty" one, and charge it for a little bit.
E.g. today, I had one battery showing 0.4V, and after about a minute
in that "fast charger", it was ready to be charged in La Crosse.
(I've done that with other rechargeable batteries too, -not only with the
"strange" one that I am describing below.)
And since we are talking about rechargeable batteries, - I've found that
recently, my "Amazon Basics" branded rechargeable AA batteries started
behaving strangely: sometimes one (or maybe even two sometimes? I
don't remember for sure) battery becomes drained to that low level,
like today, 0.4 V, while the other three are still at a reasonable
level (today those 3 were at about 1.28 V).
The curious thing today, that after just about a minute in the "fast
charger", the voltage of this battery went up to about 1.3 V, and
after that it was behaving as it was the same as the rest.
There could be two possibilities: either this battery significantly lost
its charging capacity, or it is just was "locked up" in this strange
state of a low voltage, and this "shock charging" helped to get it out
of that.
The latter is very likely, as the pencil charpener where these 4
batteries were, stopped working very suddenly, not gradually.
I haven't seen anything like this happening with any other brand of
rechargeable batteries.
In any case, I am using my La Crosse now to "refresh" this battery
(discharge-recharge cycle). That, hopefully, will show the true
capacity of the battery.
I hope this information could be helpful.
Cheers,
Igor
