[hack][TUT] Use nokia Bl-5c battery as your htc gene battery

---

guys this is my first tutorial...so please bear with me

my 2 yr old gene needed a battery change as it could give a backup of 15 mins only....and the new battery cost around INR 1000.....while going thru my junks i found a nokia cellphone which i used rarely and it had a new battery in it...an idea popped in my mind. the idea was to change the cell and replace it with the nokia cell...after inspecting both the batteries carefully...the body structure were almost identical in shape and size though the nokia cell was a little slimmer than gene's sanyo cell...the specs of gene battery "Sanyo Model:WIZA16" and the nokia battery "BL-5c" were

Sanyo Model WIZA16 :3.7VDC 1250mAH li-ion battery
BL-5c: 3.7VDC 1220mAH li-ion battery

the only thing which mattered was..I was short of 30mAh....i decided to give it a shot....

Step 1 : Dismantle the sanyo battery by removing the label covering it..then carefully removed the plastic shell covering...


Step 2 : You'll find a pcb attached to it on the side cell.Handle with care.
Step 3 : with the help of multi tester probe the terminals and find out which is +ive and -ive and mark it on da pcb.

Step 4 :You'll need some basic soldering skills to desolder the positive and the negative terminals of the cell from the pcb.after detaching the terminals as i found out the base of the cell is positive where as the other point is -negative. see the attached pics


Step 5 :do the same on nokia battery....we wont be needing the top(which includes the terminals) and bottom plastic shell
Step 6 :removed the cell from pcb...well the nokia cell has both the terminals on one side as compared to sanyo's cell (see the pics)

Step 7:after seperating both the cells from their respective pcbs....we're going to attach pcb of sanyo to the nokia cell
Step 8 :becareful wen soldering the terminals on the pcb....it should be soldered the same way as it was on the sanyo cell...or youll end up screwing the pcb.double check it again with muli tester.


Step 9 :With the help a wire...connect the negative terminal of the cell to the pcb



Step 10 :Now put the cell and pcb back in to the sanyo's plastic shell...and youre done.....put the newly refurbished battery into the gene....and let it charge for atleast 3 hrs.



for me this battery is working as a new one the backup time is great...i wonder if there would be any change in performance in this cell which has 1220mAH as compared to original cell which had 1250mAH.

hope you guys like my tutorial...its kinda short.....i know.
i'll upload more pics later....and sorry for blurry images....

thanxs !
anyways...i think nokia ngage battery is more suitable for this hack...BL-6C...its 1070mAH...but man this battery is giving great back up just as new!
and one thing more...its an advise to all gene users...avoid charging ur gene on USB...i've read it on da forum somewhere...it shortens battery life and because all batteries have a limited number of charge cycles.continously charging makes battery lose a lot of charge cycles,When battery cells finish the number of life-cycles, theyre no more useful....decreasing the total capacity of battery.So its better to charge on Ac adaptor once...than chargin it thru USB...even though its fully charged !

good job man!!

i m very happy because original batt of gene cost rs 1400 .

u have done great job! can u plz upload a video of this hack because i can't get how to disseminate old sanyo batt. i know if i did wrong all hack will waste because it can damage plastic shell and pcb also.


buddy can u tell any hack for lenovo laptop batt also??

hello
its quite easy....all u have to do is remove the sticker label of the battery....once u remove it....u'l find tape covering the plastic shell to the cell...remove that too..... after that remove the shell gently n carefully...and yeah its better to cut terminal plates from da cell by pliers....than to desolder caz the terminals are solder at the bottom side of the PCB....u can desolder it easily after.

i wish i cud upload da video....but im having really low speed...using mobile office from airtel right now...my airtel broadband failed...since last week

and about the laptop batteries....u can find amazing DIY (Do IT Yourself) stuffs on http://www.instructables.com regarding it but u'll need to find same type of cells !


njoy !
