-Charging indicator keep flashing orange color after refill. Battery fail and show 1-3-5 LED indicating when pressing the test button on battery.
-Battery don't last as long as it should be after refill.
-Voltage, current, temperature, capacity calibration for certain battery. (Some battery calibration setting run as the age condition of component).
-large cell balancing current and burn the balancing load resistor and thus the battery fail.
-Safety fuse burn when battery exceed critical operation parameter.
-Battery lo alarm warning even after long time charging or fully charged.


We garranteed that the battery send back to our customers work greater than 80% performance compare with original or else 100% money back garranty within one week from the date of purchase. In fact, most of it reach more than 100% compare with original due to differentiated technology (old battery with lower cabability) and producing date.

This will be discuss with customer. They must give a reason how a refilled battery can cause any unwanted disaster to laptop.

Any random accident happen after the battery refilled can not be directly related to battery.

Added on May 20, 2007, 8:20 pmI suggest you get a new one if avalaible, refill is only your last strategy. Off course it can be refilled. This is an 8 cells battery pack.

No, I am not familiar with camera' battery....

Manufacturer by what factory?

Capacity is very high already. Can not be increased, we only able to make it close to you original.

Designed Capacity is 48000mWHr or 4800mAH? There are never 4800mWh....
Desined Voltage is 11.1V. 6 cells.

Not sure cause never do this before, risk is too high, not recomanded.
What is the voltage and capacity of the battery anyway? Can try if you want.

And thank for you support....

First battery is usually becoz of dead cells or imbalanced cell
Second battery is because you didin't make the battery go through qualified charge/discharge cycle. This can always be solve by let the battery charge for a long period, if it stay at 40%, just let charge longer untill it reach 100% and then let it discharge to less than 3%. Do this a few time will clear the digital memory effect of your battery. If it never reach 100%, it mean the battery can never meet fully charged condition set by the manufacturer, should this occur, there are serious cells imbalanced impedence exist due to wear and tear.

If the second battery do reach 100% after long time charge, I can correct you battery problem without open your battery, just reflash the battery data. Else, I can make it back to normal by balancing you battery cells.(But I think it won't last long , may be sustance for another months for smooth charge/discharged experiences).

Anyway, to place an order, just mail to order@altbattery.com or visit our web www.altbattery.com for detail.

No PM will be replied, PM box always full.

Added on May 30, 2007, 9:15 pmImposible, you battery cell sized at 17670 that is the capacity it should be.
14.8V 4800mAH only can achieved with size 18650.

We not able to put in bigger cells into the plastic housing of your battery, even if we do so, you will fail to slot it into your laptop...

Similar questions can always be refered to Post#2.
PM you already....

Can be tried but not 100% garrantted this can be done cause there are some of this using different fuel gauge integrated circuit which beyond my capable to handle.

Just PM me your phone number to proceed or mail to order@altbattery.com(Faster response)

Can the battery still back up power for a short period?

Capacity upgrade is quite difficuit on modern laptop which comsumpt larger peak power. It won't make big different even if I put in 4800mAH cells in total. 8 cells in total will give you 4400mAH. RM219.

By the time you do a deep discharge and fully charge, the battery doing self calibration and update the wear level. This is normal for all battery, no one can expect a battery with wear level of 0% after a few months of usage.

Please note that no any charging method can recover lithium ion type of battery in view of it real performance.

Just send it to ALTBATTERY to refill after it wear level reach unacceptable level.

Many people asking me for high capacity cells, I will say not recomanded, high capacity is not as safe as low capacity battery, especially those reach 2600mAH/cells. The high desity of the cells required elctrode and dielectric from very thin material, this tend to puncture the dielectric (if the electrode deform due to wear and tear) and result in internal short circuit. Although the rate of happen is very very low.

Never look for the best, instead, look for suitable. In the other word, suitable is the best.
