how much for dell 510m??11.1V 4800Mah....

can get better capacitor??

Imposible. With the size of your battery. It is the maximum Capacity/Weight already within current Li-ion battery technology. You battery pack using 2*2400mAH Sanyo redcap. We maximum able to make it almost 100% close to it original performance only.

After Sony out, Dell adapt Sanyo.

Li-ion cells (18650) capacity list (a rough note, not comfirmed to actual statistics but very close):
1993-1997~1300mAH(can be used approx >5 years) with technology at the time.
1997-2000~1600mAH (can be used approx 5 years)
1999-2002~1700mAH(can be used approx 4-5 years)
2002-2005~1800mAH(can be used approx 3-4 years)
2003-2006~2000mAH(can be used approx 2-3 years )
2004-2007~2200mAH(can be used approx 2-3 years )
2005-2007~2400mAH each cells. (can be used approx 2 years )
2006-2007~2600mAH each cells. (can be used approx 2 years )

Of course, some party try to use special charge/discharge tecnology to boost the capacity beyond it design capacity but usually it is not pratical and expensive. Higher capacity damage the cells faster due to highly active of chemical response.

Li-ion battery chemical are charging every half to one years. To maximized the output power capabiliy and it capacity. But it Capacity/Weight almost in peak already. Only Power deliver/Weight increase recently.

Price for refill your battery is RM160 (6cells). With 3 months limited warranty. First week 100% money back gurrantee if you are not sastify with the battery performance.

met this guy yesterday and he took about 3 hours to get everything done.
my 'new' battery took about 3 hours to be fully charged and another 3.5 hours to be fully discharged.

im loving my battery now.
no more carrying the AC charger around the house.
yay!

thanks a lot!

if i buy a new twinhead battery - rm500
i refilled my battery (up to 100%, maybe more) with him - rm160

so, again, im very grateful.
will keep u updated with the performance of my battery.

You are welcome. Your pay for what it should be. Prices is just relatively. Not absolutely. In bussiness, sometimes people pay slightly high price for low quality, sometime people pay slightly low price for good quality.

Thank for your comments.

But in fact a refilled battery is not always recomanded. It involve certain risks. We try to reduce the risks to minimum. So user can just treat it as a "new" battery.

But please note that it is not a new battery.
The circuit board inside the battery pack have cycle life. Once it exhaust
not function anymore). User may feel disappointed. But don't worry, this only happen on 1~3% of customer according to my pass experience. We held the risk for one week for both battery circuit board or user notebook intenal charger problem which make the battery not seem to working. We held responsibility for the battery cells will work for 3 months. The remaining risk is on customer.

how long u time u take to refill??

Hello...

NEC Versa E400 battery can refill or not??

Depand on my shift. Will do fast upon customer request. Usually you send me the battery, once I recieved and proceed will send it back to you next day.

Can, 95% of success rate. 5% fail due to battery leak, the liquid inside make the circuit board rusted thus not functioning. We can open this model very nicely.

Mine NEC VERSA M540. interested here.Please PM if available.

Thumbs up to Altrafield for reviving my dead battery. Now with the new cell, I can enjoy an "AC-less notebook freely". Excellent service with extremely fast return.

The revival work was done overnight. I got my battery back the next day conveniently. Great workmanship as there is no "prying" marks on the battery casing. It's as if you got yourself a new battery but at a fraction of the price....

Practice make perfert, more than 40% battery pack can be opened with not "prying" mark if user are not in hurry. Another 40% can be opened with very little mark and 15% with very noticeble mark. 1%~5% of it is very dificuit to be open and thus break into pieces (I will info user before I try to open).

hi, possible to replace cells for nec notebook battery , if not mistaken m400!

pls pm me so that i can bring the battery for you to have a look!

my contact 017 338 3008, tq.

hello viking...long time not see...

hehehe... (old friend...)

Viking just "tumpang" tread only, making some advertising here. Don't even pay me a single sen...

Afair of misleading, so emphasize here.

hello Altrafield.

I got 2 unit of Compaq N610c battery i would like to refill.

Can you get this unit done?

How much do u quote for 2 unit, maybe can ge bulk discount

sorry for basic question, how you/they count 6/8/9 cel? Is it base on the number of Li Ion battery?

Usually a few smaller unit call cells is combine to become a larger and pratical unit call battery.

Engineer decided the minimum number of cells required for specified device. The battery pack must be able to output enough power for the device to comsume or else the battery are forced to operate and will die soon due to overheated.

How to know no. of cells use in a battery pack:
3 cells 10.8V, 11.1V 1300mAH-2200mAH
4 cells 14.4V, 14.8V 1300mAH-2200mAH
6 cells 7.4V, 10.8V, 11.1V 2600-4800mAH (up to 6550 for 7.4V model)
8 cells 14.4V, 14.8V 2600-4800mAH
9 cells 10.8V, 11.1V) 4800mAH-6550mAH

how can i reach u?

By post or COD around KL area. Eg.KLCC.

Promotion for this month (March) only:
-All customers get their notebook refilled with 2200mAH or higher capacity battery cells. Usually we use 2000mAH. Stock only available this month. While stock last...

PM me if interested...

The battery label 2400mAH but we test by sample it close to 2300 only, So we treat it as 2200mAH standard.

If your battery is 4400mAH (2200*2). It will be exactly or more than 4400mAH.

Hurry, we don't want to keep stock, li-ion battery cells performance will degrade as time passing by eventhough it is not been used. Don't be hesitant, if you want to pay for the same thing, better pay early to get more out of the battery cells.

No one can offer this promises on the local market with this price. First week 100% money back garantee if you are not sastify with the battery performance.
