Hi,
i have one question: I have recently bought Nokia 3310 with Ni-MH battery. In the store, the said that i need to charge battery fo at least 12 hours and then completely discharge it. I should do this 3 times in a row.
This is called "preparing the battery", as they told me.
I don't know much about celular (mobile) phones, but charging for 12 hours seem pretty much.
Is this true or not?
Thanks in advance
Andrija

Sorry, I don't follow that rule, I just plug it in and start using it. Although I do make it a habit to fully drain my batt before charging it.

Let's try to clear a few things up here...AFAIK!!
If you have a Nickle Metal Hydride(Ni-MH) battery you should give them a long charge overnight the first time. Then, where possible let them discharge fully before recharging. The idea is that it stops the "memory effect" that is the battery begins to lose its charge quicker and quicker!
Now, to my knowledge, if you have an newer model nokia with a Lithium Ion (Li-I) battery..they don't suffer from the "memory effect" so you can recharge them whenever you like. Also there is no need for extended charging the first time.
However, all batteries eventually can't be recharged..or star to lose their charge quicker than they used to. You can usually just be a new battery but hopefully, by this stage your phone is old enough and shabby enough to warrant buying a new one

Its always best to charge ALL batteries for at least 8 hours for the first charge... so that the batteries individual cells are all full to some degree.. With NIMH its always best to do the charge then recharge thing 2-3 times to get the most out of it and at least once a month discharge it altogether (until the phone turns itself off)
Li-Ion and Li-Pol batteries don't have the memory effect that the older types (NIMH) did but its still always good to do a full discharge once every month or two.
I've found with my last couple of phones that the batteries have lasted longer (both in terms of longivety and talk/standby time) if I've discharged them... I found that if I didn't (ecspecially with a NIMH battery) that the battery life diminshed considerably.

I guess it can't hurt do a deep discharge every now and then. I may just take your advice!

Actually, if the li-ion battery hadnt had circitry that prevented discharge, a full discharge of a li-ion battery would damage it. It shouldnt be charged more than 3 hours the first time and you should not drain the entire battery to often as li-ion just loves to be charged long before its gone out. Of course, every charge weakens battery life due to corrotion on the positive plate, but there is no workaround that. Also, if you want to buy a new phone, check the manufacturing date. If its like 1years since manufacture battery may be down to 80% capasity depending on what temperature its stored in. If you dont plan to use your phone, you should store it while having 40% battery remaining to limit the corrotion. At last I want to say that a full discharge (which actually isnt a full discarge in reality) only helps to calibrate the "fuel gauge" so that its more accurate. This can be done once every month or so. My two cents about batteries..
