*A power bank convert cell Voltage (3-4.2V) to 5V, there are loses in the conversion. Conversion efficiency drop below 75% at output 1.5A, more heat generated.12000mAH@3.7V able to output 7577mAH@5V, that mean if your phone battery is 1440mAH, 7577/1440~=5.2, it able to fully charge the same phone ~5 time.

*Some people misunderstand the concept of mAH and Wh, I give you example mAH is quantity, Voltage is quality, Wh is amount. Example: RM10 note is quality, how many pieces is quantity, amount is number of RM10 note multiply with 10. Example one covert 10pcs RM5 note to RM10, get 5pcs RM10 note, it do not mean that you end up with 5 pcs paper so the conversion efficiency is 50%, RM50 is still RM50, you have no lose in this case!

Same thing 10400mAHx3.7V=38480mWh or 38.48Wh, when it convert to 5V, 38.48/5=7696mAH, this is the case of 100% conversion. At 80% conversion efficiency, one is more likely to get:
0.8x7696=6157mAH.

Example run time for 10400mAH(6681mAH@5V USB) model:
Galaxy Note 2 (3100mAH battery, 6681/3100=2.16), ~2 time 100% recharge
Iphone 4 (1440mAH battery, 6681/1440=4.64), ~4.5 time 100% recharge
Ipad 2 (6944mAH battery, 5863/6944=0.84) ~84% recharge
Ipad 3 (11,666mAH battery, 5863/11,666=0.50) ~50% recharge(efficiency drop to ~70% make total output drop to ~5863mAH only @ 5V 1.5A)

*Maximum output is 0.5A (small phone), 1A (smart phone, note phone), 2A (tablet, pad) select-able through switch at side. Limit the current will increase it conversion efficiency, extend battery life, but slow down charging. Set the current above what required by device will have no noticeable effect,but if your phone show "charger is not supported", most likely the current too big, set it to a lower will charge your phone, the charging circuit of phone will limit the current, but it is advised to set the current limit according to your phone charger.

*100% money back satisfaction guarantee!
*See first post for a collection of user feedback!
*Dear user, please understand that your battery is not 100% refillable, I will try all my best to fix every single unit as perfect as possible. Unit failed will be refunded the amount buyer have paid or your can sell it to me as used part. I will not held responsible for any battery fail to be refilled or unit fail after refill, don't ask me to revive it, it fail because the chip inside rendered it unusable during new cell connected, and it could be irreversible. Please note that some battery model only have 50% success rate. By contact the number above, mean you agree with this. If you have anything you don't understand, please ask first before proceed. If you want to know success rate of your battery, please PM me your battery model. Some battery (<5% of notebook battery on the market) can also crack easily because of the material used to built it, please ask if your battery belong to this type.

Frequently ask question:

Q:"How many days are required to fix my battery?"
A:1-3 days unless otherwise notify.

Q:"How much price for refilling my battery?"
A:RM80-300, depending on the number of cell and capacity customer want.

Q:"Why it seem like RM30-50 more expansive than a 'new' battery?"
A:Quality is the primary reason. Cheap battery mostly just last 1-2years for light usage or 0.5year to 1 year for heavy usage. While the Samsung cell refilled unit normally last 2-3years for light usage or 1-2years for heavy usage.

Q:"Why refilled unit is just around RM50 cheaper than original battery? Isn't it suppose to be much more cheaper?"
A:That is incorrect, some original battery is sold at RM700! Many customers fail to get original battery because it is obsoleted. The key component of a battery is battery cell, the other part such as housing and electronic inside will not cost more than RM50, beside, it need workmanship to open, checking, install new cell, verifying working condition to ensure customer get an excellent battery. If it become too cheap to go, the refilled battery's performance is usually very unwarrantable. Most seller do not have enough patient to 'waste' their time to fix a battery just for small profit while they can sell many 'new' battery for the time given. In fact, mass production of electronic item at lower cost have huge impact on many electronic repair service, for example, people will buy a new DVD player instead of get it fixed at much higher cost than buying a new one.

I suppose its way overdue for my "review" of this seller and product.

Had my Thinkpad X61's 8 cell battery replaced with new cells. getting around 6 hours of use which is as good as the original ones. been using it for a month and has been reliable so far.

sure beats the useless china made packs sold in LY which only lasts 2-3hrs and dies off in 1 year or so....which are sold for 220-230...

paid 250 for the re-cell and it has been worth it.

QUOTE(aina_chan @ Jan 20 2011, 02:18 PM)

I'm glad I didn't go for the overpriced original battery, not to mention that they only have black colour while my laptop is white.
The battery last up to 3 hours during normal usage (wireless internet surfing with WMP playing and microsoft word open).
It lasts about slightly more than 3.5 if I just use microsoft office, which is really nice for a student.
I don't have to hunt for power outlets when doing discussions anymore.
My father was also very happy with the battery too. He wasn't very keen on 'realt-ing' but he changed his mind straightaway after he get back the battery since he didn't have to carry the AC cable even when giving out a 2 hours lecture with LCD hooked up to it.

Very good service too! I didn't wait long at all. Posted on Thursday, he got it on Friday, and even when he said it'll take some time since he got some batteries to work on, he had posted it back to me by Monday and I got it on Tuesday.

Thank you so much!!

More feedback can be found below and along this thread, all of this is real user experiences! Proofs of quality work and stuff! You can even leave a long term usage feedback here! Most user found that it last long enough like an original battery! And of course there are some minor case where the battery is beyond my ability to fix it!

Professional Laptop Battery Repacking Service! The highest battery refilling success rate as you could possibly found in within Malaysia, Click me to know why? If your battery can not be repaired, you will be informed at the beginning, unless I never recieved the particular model before, unable to find your laptop battery? I can help you, quality assured or your money back! You can also sell your battery pack to me for some RM (*want only model in within 5 years from now).

Alternative Battery can unlock and calibrate more than 90% of laptop battery that comply with Smart Battery Specification 1.0 and 2.0 that using standard cell. There are around 80% of battery on the market is standard of Smart Battery Specification. And battery reach my hand, if not fail at the begining (liquid damage or other damage) or just fail not too long, typically have 98% of success rate, every 100 customers, only 2 of them fail to get a fully working battery from me! From those fail one, there are few reasons, some of them is because the notebook internal charger fail, notebook adaptor fail or some bug occur in the circuit due to wear and tear, such as battery gauge 'hang' (some gauge don't utilize watch dog timer, it don't reset itself when it 'hang'), or minor component on the board fail, such as some capacitor, diode or transistor fail, result in measuring fail and cause fuse blow.

Hi quality cell same as those use in your battery pack, cells life last up to triple time longer than "cap palang" cell! Quality approved by Low Yat forumers since years 2006! 1st month not satisfy 100% money back gurantee, 6 months limited waranty (get it fixed or 80% money back no matter it is cell problem or circuit board problem), 1 year customer care service (if cell is ok but circuit board fail, can try to repair at zero cost to you!)

*Zero cost doen't include postage fees, I don't charge you for the repair job. So far only 1 person use 1 year customer care service as the insolated copper connection to measure cell voltage broken because of pressure of bent metal strip, after I solder it back the problem fixed. I wish less customer use this, so I only give everyone something that can last!

Some original battery that are used less than or around 100cyles, that fail after 2-3years (because cell have minor differ in self-discharge rate, but user always keep it full), usually can be balanced the cell capacity level and restore it back to around 70%-80% capacity of it original condition. RM30 to proceed this case, 1 month waranty upon repaired battery.
