Hold on
so what are you ppl saying

coz wse all know the batterly life of these phones isnt great.

If I want to get more time outta my battery I gotta buy a special charger do I?

If so whats the exact name of this charger?

Thanks in Advance

look at the picture of adrian was loading the battery on 8250 there when U look the picture ,U will on the battery pack that needs special charger!! if you check the nokia.com accesories there U will see 3310,3330,8250,8210,8319,6250 etc, all these batteries can charged by NOKIA charger DDC-1, charger can charge LION and NIMH ,lion 750 and 950mh,thats why I bought 950mh as extra battery!! when U buy the battery just with what kind of charger has to used???

[muratti54]

with charger NOKIA DDC-1 the phone is completly free,cause when U have the charger ,U charge only with the charger!!what I mean is ,when U charge the battery on the phone,there is a always risk of changing the voltage can make the phone easly defect also ops: extra charger like DDC-1 is always usefull in anycase

... hmm, isnt it a bit annoying to open the phone and change the battery each time? Btw, when I recently changed the battery (I have two 750s) the phone lost date and time and I had to set it again - is this normal?

[muratti54]

what do you mean??when U 2 batteries ,U change it anyways!!with date settings ,I have no problem

[Freddie666]

no, normally I dont change it - have the second only in reserve for the case I cant load the phone, but didnt need it until now. Only one time I changed it to load the reserve battery, and that time the phone lost date and time - perhaps I was too slow

[muratti54]

so U bought as a step BLB-2 and U paid 40 euro?

[Freddie666]

yeah, like Elvis said: A fool such as I ... but I like original accessoires ...

wait a minute... Check your charger that comes with the 7650. It says 5.7V and 800mA. That is different from the charger for the 8210/8250, which is 3.7V and 355mA. The difference between them is that one is a fast charger and the other is a slow charger. All can charge the battery, but one is quicker than the other. You are supposed to slow charge a battery when it is new, but then Nokia gave us only the ACP12 which is a fast charger.

Also see the extract from http://eurobatteries.com/sitepages/batteryglossary.htm :


Charge batteries with a DC current, positive terminal to positive terminal. The voltage must be greater than the battery or battery pack voltage. The current must be limited and the current cut off when the battery is fully charged.
Full charge is sensed either by a rise in voltage, a rise in resistance or a rise in temperature.
Battery chargers are designed to supply a suitable current for the batteries with which they where designed to work.
Unless chargers are labeled otherwise, remove the battery after 16 hours.
More sophisticated chargers will switch to a trickle when they sense the battery is fully charged. This is fine for Lead-Acid batteries but NiCd and NiMh should not be left on ‘maintenance’ charge for more than a few days.
As a rule of thumb, the charging current is one eighth of the Ah (in Amps) or mAh (milleamps) rating of the battery. A full charge takes about 1.4 times the label capacity.
E.g. NiMh Battery 1800mAh capacity
Charging current 1800 divided by 8 = 225 mA
Charging time 1800 divided by 225 x 1.4 = 11.2 hours

At no time should the temperature rise much beyond blood heat.

Unless nokia are crazy the 7650 should have a Lithium Ion battery (or variant) in which case it makes no difference with slow or fast charges as there is no memory effect as seen in NiMH and NiCd batteries.

[adrianbaby]

It does have Li-ion battery... BLB-2 is a Li-ion battery the last time I check.... is it not? :roll:

[SwitchBlade]

I wouldn't know I'm a 9210 owner, I just spy on you people

/me hurredly sellotapes camera to phone

no I lied I have a 7650 (kinda)

So where are we at here?

Adrianbaby, how have you got on with you new hi cap battery? Any improvements? Any how are you charging it or are you waiting to purchase a DDC-1? I really dont want to have to remove the phones battery every time that I want to charge it.
