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.

Adrian

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

My question is, does the 7650 have a lower threshold before it deems a battery "flat"?


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 :D

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 :oops: , 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... :D

Adrian

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 :oops: 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.

Adrian

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.

tell us a bout your highcapacity battery??do U have now much longer standby time?

Wait a minute guys and gals!!! As I said I only got my battery yesterday morning!!! I will report back after 3-4 charge cycle, when the battery is supposed to be "properly charged and ready to go". And sorry Muratti54, I'm no expert in battery charging. I just charge the battery with what Nokia gave me. I believe you just need to charge it a bit longer for high cap battery. There are numerous sites on the internet teaching you how to charge batteries. The site I quoted, I believe, is just teaching you how to do your FIRST charge. There is no way you need to charge it for 15.4 hours each time. I used that site cos that's the only battery site I bookmarked (cos they sell batteries which I might be interested in in the near future). Will post again when I find a better site on charging.

Adrian

Try this site for charging info.

Oh and I forgot to mention that the cover doesn't quite flush as well with the phone using the high cap battery. Reason being that there is no rails on either side of the cover. See pic.

Adrian

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 :oops: , so maybe I can have a battery for my b'day :roll:

why is it you need to persuade ur gf for a new battery.
Not really a heavy expensive investment isnt it? :roll:

Different family/relationship dynamics man! :oops: I always consult her before buying anything she would consider "junk". ;)

Finished my 1st charge cycle. Managed to last 1 1/2 days with about 1 hours of games, 15 minutes talk time, another 30 minutes of miss call ringing (to drain the battery :oops: ), 20+ minutes of midi playing etc. ie lots of playing, trying to drain the battery. Charge time is just over 2 hours. Initial indication is that the battery is much much better than my old "imitation" battery. Not sure how that would compare with the guaranteed original 750mAh BLB-2 however.

The guy at solware.com, where I got the battery from, said I should charge it like a normal battery with the original charger.

Adrian

Then don´t you need remove the battery to charge it?

They told me that I should use the charger that came with the phone.

Also the destop charger use the same "transformer" as the normal charger does it not? I mean all you are doing is plugging the standard charger into the desktop unit. Effectively you are charging with the same charger. Am I right? Or maybe you can tell us what the numbers are on the charger itself.

Adrian

I use the charger that Nokia gave me, but Muratti54 says that when you charge the HighCap battery on the phone, always there is a risk of changing the voltage... Is dangerous to charge the batt on the phone without remove it?

To be honest, I don't know. There are webpages on the science of Li-ion battery and charging it etc. I remember reading somewhere on those pages that optimal voltage for a 3.6V cells is 4.x Volts. If you look at all the charger "approved" to be used to charge the BLB-2, they all have different Voltage and Amp ratings, ranging from ~3.7V ~355mA for the ACP7 (came with the 8250) to ~5.7V ~800mA for the ACP12X (came with the 7650) [need to check the figures to confirm]. Confused. I am!!! :D

If you ask me, then I would tell you just charge it with what they gave you. I don't think it really matters that much. The desktop charger is something that allows you to charge a spare battery at the same time in my opinion. I really don't know. I don't think many people REALLY understand it either.

Adrian

Thanks for your reply. Well, I think I´ll wait to Nokia releases a High Capacity battery for our 7650! ;)
Regards!

I would not reccomend buying an 'unofficial' battery (i.e. un-Nokia ones) unless you know you can trust the brand.
I bought a BLB-2 clone off E-Bay for £10 and it worked fine for about a day, then on its second full charge cycle it expanded (litterally physically got bigger) so much that it popped the cover of my 8210 right off. It now won't even fit in the phone, but thats probably a good thing, god knows what it could do.

lol man I would have loved to have my nokia 7650 there to take a picture of ya expression where ya saw that the battery has popped the back of ya cover off :P

Thanks for your reply. Well, I think I´ll wait to Nokia releases a High Capacity battery for our 7650! ;)
Regards!

Yes, I was told at the electronic market "Cosmos" in Vienna that in one or two months there should be an original Nokia high capacity battery for the 7650 ... I think I will wait for this too ...

I actually have the phone on the 4th day today on the same battery. The trick to keep it alive was not going for the extended battery, but i had used the old trick (used on old phones like 6150), changed the codec order to HR->FR->EFR. By default the phone does EFR->FR->HR. Putting Half Rate first lowers the quality of the codec, but battery lasts longer. Anyone got the phone alive for 4 days yet ? I'll see tomorrow if i can get 5, the battery is almost out 8)

I remember someone mentioned the 1250mah battery from an italian site. They replied and said the battery will be available from 16th Sept and they will ship to UK... so I'm sure they will ship worldwide at a cost of course. Their website is:

www.nixie.biz

On my second charge cycle now. Made a few calls, send some text, used some of the programmes, some games... what I would call normal use, the battery is now 3 blocks after 1.5 day use. I am sure this will improve after the 3rd and 4th charge.

Adrian

Um... how ???

Had another email from nixie.biz They said it will now cost 45.36 euro to DHL it to UK!. Need to preorder as well. Very expensive if you ask me. Can almost get 2 1100mah battery at that price...

Adrian

In a service center, with original software :cry:
