Hi all,
I am using a imitation battery on my 7650, which I believe is normal 700mAh capacity. However after 5 full charge cycle, I am still getting only 15 minutes talk time and 1 day standby. At first I thought it is the battery, but then when I swap the "flat" battery to a 8250, it shows "3 blocks" of battery power.
My question is, does the 7650 have a lower threshold before it deems a battery "flat"? Would you advise me to use the original 700mAh battery that comes with the phone (which I wanted to save for my gf's 8250, whose battery is near death), or shell out �14 for a 1100mAh hi capacity battery? Thanks.
Adrian
same thing keeps happening to me where did you see the hi battery from as i want to order one
Hi there,
If you are in the UK, the cheapest you will find on the net is:
http://www.1st4mobileaccessories.co.uk/batteries.shtml
http://www.shopsmartshophere.com/nokiabatteries.shtml
http://www.solware.co.uk/batteries.shtml
If you look carefully, all three site are the "same"... supplied by solware.co.uk, the last link.

So you think I should try the Hi Cap battery then?

I guess the 7650, when it has the display on and the cpu working hard, has a much higher current drain from the battery than the 8250 and the non-original battery can't keep up with it, so the output voltage falls below the threshold much earlier. It's not only a matter of charge capacity, it's also a problem of maximum current.
I do agree with you lele, and that's exactly what I thought is happening...
But is that a problem with the original nokia normal cap battery? I am leaning towards getting a high cap battery since now I have an excuse and my gf agrees with me... no need to convince her! 😉
Sorry to bring this up again but what is the general experience with original normal cap Nokia battery with the 7650? I want to know whether it would be worth my while shelling out �14 for the high cap battery. Thanks.

Yes, shell out. On a good day without much use or any calls it will last 2 days. I tend to have to charg mine every other day. I've got a high capacity battery waiting for me when I get back to the UK next week 😊
Exactly like Taomyn said: 1 day with much use, 2 days with less use. But another question: Anyone here who knows where to get a high capacity battery in middle europe, especially Austria? I guess it would be rather expensive to order it in UK and get it sent. Thx for your help.
So has anyone got one of the high capacity batteries? How much longer do they last? Do you really notice the difference? Seems like they are only half as powerful again which is not much really.
Same as Taomyn here too. I'm finding I can talk with it for ages and it doesn't seem to chew the battery up too much. But actually playing on the phone particularly if that back light is running you can kiss the battery life good bye pretty quickly.
I remember the first day I had it I dont think I even got 6hrs out of the battery. But of course thats a boy with a new toy 😃
Since then it's been 2 days.
Oh and any thoughts on the high capacity batteries availability in Australia?
Someone posted this link http://www.nixie.biz on another forum.
It links to an Italian store selling a 1250 mAh Battery. Looks the real deal. Maybe it would be worth hanging on until it comes into the wider market?
36 Euros is about �22.68 according to my 7650 convertor program!
Thank you all for replying... I shall "persuade" my girlfriend that I need a new high cap battery. But then, it is my b'day tomorrow 😮ops: , so maybe I can have a battery for my b'day :roll:
Hi all,
I have checked out the italian site. The 1250mah battery is not available yet. I have emailed them asking when it will be available whether they ship to overseas. Will update you all if he/she replies.
If you are also looking for a high cap battery, a 1100mah will cost �14 free P&P in UK. Use the links above.
For slightly more value for money... depends on how you look at it, a 950mah will cost �11, also free P&P. Here is the link:

If you find them any cheaper do share it with us... 😃

My battery has arrived!!! Ordered it on Thursday midnight... so effectively Friday morning, and it arrived on Saturday. Ordered it from Solware.com, good service. Only "complain" is that the 1100mah sign is stuck on with sticky-back paper, with a plastic file round the battery (except for the contacts of course). See pic. Will report on the batter life after a few cycles.
Adrian
PS note that I am charging it in my GF's 8250 so that I can still play with my 7650. :roll:
I bought 950 mh lithium battery for my 7650 and paid for it 14.99 euro!! it fits in phone with a maximum limit,if abit bigger the battery more than 1 mm wont fit to phone!!! the battery cover is in away very weak,so it can easyly breakdown! I also bought the Nokia charger DDC-1 which I found very usefull!! my phone is always free,I dont need to charge the battery on the now always on NOKIA charger!!so I can always load the battery perfectly through the charger!charger costs in amazon.de 39 euro original assesories
it is not possible to charge the high capacity batteries on the phone,U need a special charger!!! :roll:
muratti54,
Thanks for telling me about the charger. Which charger do I need to charge the hi cap battery?
Adrian
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???
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 :evil: 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?
what do you mean??when U 2 batteries ,U change it anyways!!with date settings ,I have no problem
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 😊
so U bought as a step BLB-2 and U paid 40 euro?
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.
It does have Li-ion battery... BLB-2 is a Li-ion battery the last time I check.... is it not? :roll:
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.
