Change? Not recomanded. Most of the battery that in contact with water will subjected to liquid damage, I forget to capture the picture last time I do one. Otherwise I can show you. Unless you tell me that the battery only get a split of water not dump into water.

Mostly can be fixed, more than 90% twinhead battery can be fixed. But sometime, fail to "ON" with battery may not be the battery problem. You can send us your battery and we will judge if it suitable for refill.

If the battery is under output disabled state, can be enabled by reset some flag in the battery system cache but the life of the battery is undetermined by any scientific mean. Once it fail, it will fail randomly not direct propotional to time. But usually can be used for more than 3 month again since it is quite new. This is how, many people fixed the battery, rebalance the cells voltage and enabled it to reduce chimical waste since it still usable.

I always try to figure out if it is notebook problem or battery problem that cause the battery only last for ~one year nowaday. Last time it can last 2-3 years. I suggest it is battery's cells problem. Beside, high capacity and high power output capability cause the battery rushing (highly active) in the begining and thus exhaust very fast. Just like in a long run, you try to run very fast in the begining, although you are No.1 in the beginning, you won't won at last unless you are phisically x time stronger than other participients (do you think this is possible?)


Strongly recomanded.

Not more selling any second hand battery.

mail your address and phone to order@altbattery.com.
will collect from you if convenient or will give you office address and you can sent to office.

Cost is depend on number of cells.
Battery should last for more than 3 month, we give a 3 month limited warranty.

Honestly, hope don't see this kind of question. many people ask.
Why don't just tell me what you expected. If I can do it I will let you know. What for I tell a lie (something I not suppose to know)?
I think it is reasonably good since no body complain since my first customer on last years September

If some body ask:
"Can the battery last 10hours and last for ten years?"
I will tell him "no".

"Can the battery do a 3hours standby and can be used for more than one year?"
I will probably say "yes".

This is more easier to answer.

This is not a scientists team (involve huge amount of work, example the manufacturer) work to study the fate of a battery. What we know there are a few reason a battery can fail. Everything come with risk. I can't just tell you, "ya ya, it confirm last 3 years. "

The world is random (any unexpected things can occur) and we promises 3 months (some people promise one year, more risk, more expensive. Some people not warranty also expensive), this is the best we can do. If within 3 month, you found that the battery not gonna to last for X months and you have doubt, then you can send it back for us to inspect.

Hope no see this type of question anymore.

I really hope people understand what does it mean by warranty.

We currently think of giving one year warranty on next year. Battery is something wear and tear, people should not expect to exchange a free new unit every time it drop to let said 60% wear level after it warranty near end. In fact, many modern battery is design to work approx one year. I think many people know this. Some manufacturers not even give one year warranty for their battery, mostly six month.

RM179. No problem.

Just mail your contact and place to collect and place to collect to order@altbattery.com. Will discuss and determine time to collect with customers. We prefer to collect a few from the same area in a day.

Thank for support, I think Pos Laju is good too. RM5.20 (for a battery) can reach almost anyway within Malaysia. The whole process for

you send->we receive>we send back

take approx one week.

Battery model?
Mostly we can put in 8 cells to make it stand by longer.
Mail us immediately to order our service.

Since some customers report that their notebook internal charger not function.
A stand alone smart battery charger is also been developed by ALTBATTERY research, currently compatible with ~30%-50% of smart battery in the world. Will upgrade the firmware to make more battery compatible.
-SBS(smart battery specification) version 1.0/2.1/3.1(with PEC transfer protocal) compatible.
-Up to 3A charging current. Charge to 80% within 2 hours and fully charged a 4400mAH in~3.5Hours for most notebook battery.
-Using SMPS, High charging efficiency >90%. (Generate very less heat during fast charging)
-Maximum 200mV stepping voltage.
-Constant current, constant voltage charging (current loop inside a voltage loop) algorithm.
If anyone interested can give some comments.

No compatible with:
-Dell with ExpressCharge(TM of Dell) system.
-Fujitsu and some Toshiba no SBS comply.
-Compaq special battery with built in charger. (E.g. ARMADA(TM of Compaq) series)
-Old Asus or Old IBM with one-wire(TM of Dallas) protocol.
Will add support upon request.

The stability of the system is still under testing. Will upload some picture if ready and upon request.

Beside, we are developing a simple PC based oscilloscope with sampling rate<10ksps, suitable for testing application deal with 50Hz AC signal to examine the waveform, or use as fast multimeter (for voltage measurement). Found mostly useful in AC switching(thyristor/SCR) testing/study. AC linear power filter study and others(no recommended for end user except low voltage application testing, e.g. study on Secondary AC voltage characteristics of transformer.)...
If anyone interested can give some comments.

As long as there are space for it, it can be fit in 8 cells.

Your battery can be refill, just post to us.

Some snapshot of the prototype smart charger.
Actual size can be smaller, this unit contain some extra function for debugging so it is bigger.
Notebook battery repairer are welcome for inquiry.

We can custom made a specified connector head of your battery(In case user only use it on fixed type of battery).

F.A.Q:
1. Is charging battery in this way safe?
This is what we are testing now. This unit contain hardware current limiter which keep monitoring the charging current. In case the charger's controller hang, in built watchdog will reset the charger. Beside, all smart battery have individual cells over/under Voltage protection/over current/overcharged/over temperature protection inside of them. As long as user never have their battery modified to force the charging of the battery, it is considered safe.

2. What is the price of this unit?
This depend on market demand and user. The price is not set yet. If interested can PM me.

3. Can I get this on local market?
No, this unit is more close to factory testing equipment. Thus very rare used by end user.

Please refer to post 183 for details and specification.

P/S:
What does it mean by double protection in a smart battery?
Double protection is the minimum requirement for smart battery, and some battery contain triple protection. The idea is, first layer of protection monitoring the charge parameter are within safe boundary. It will control and disconnect the cells from system (notebook) when any critical error occur. The second protection is a standby unit. It just a simple (mean more robust) unit to monitoring the cells' voltage only, second protection have critical value set higher than the first level, so first level will trigger first if error occur.

But first level can fail after wear and tear. When first level don't action if battery over safe boundary, the second level protection will trigger, and battery is permanently disabled. To ensure that the battery are safe.

Disable the protection can alive a dead battery, but the battery is not use in good way. It keep source current into the system even the battery are nearly exhaust. This can result in shortened cells life. It keep charge even if overcharged or short, this can result in failure of battery charger when some specified brand of cells is used.

In conclusion, a good practicing to repair a battery is keep the protection alive and test if it is functioning.

Attached thumbnail(s)

checkpoint:
Post 188 to 192 will receive PM. If not please info me thank.

Just back from SG for a local research. Have not access to internet for many days, so not log in....
Thank for the comments, Altbattery is only one of my small project. Not hope too many people know, especially the notebook manufacturer. Just introduce to your friends by oral. Price is based on our judgment on the market value upon supply and demand law. We are always based on "You paid adequate, you get adequate" law. Since our R&D cost is relatively lower that those of notebook battery manufacturer and it is obviously a repacked battery pack is not a new battery pack, it is always cheaper.

The main objective of ALTBATTERY is:
100% tested and sastification.

Ok, I will ask him to check...
I seldom want to deal with sale related issues.

thank you very much.

It is no convenience to tell. What can I tell is we give what our customer satisfy with. Just no people complain about it up to now.

Ya, you must send, only~RM5.20 post fees. You battery have very high probability can be refilled.

Can try but not big change for a perfect result for you A6020 battery. There are some technical uncertainty for us.


Sorry, no selling battery, may be you should try their service center. And thank for your inquiry, I am really sorry about unable to help.

If looking for Dell font insert hot slotted battery can look for me. Have good price.

No. How do you change? We spot weld the battery, not by soldering, ensure long battery life. Changing don't guarantee working if you don't know why it fail.18650 cells price

Mostly can. Hyundai notebook I never detect a single case which the fail is on notebook.


RM219.

Unfortunately, no one can be told what is the different, you have to see it for yourself. Just like why some people like to eat KFC, some like to eat MC Donald. You can only trust something is different. We won't let you down, just like we never make a single customer here disappointed if they manage to get our service. We work hard, we want to ensure we are the customer, and we receive something we want. Please learn that everything come with a price, no forever free lunch, we must work!

Just like why intel Pentium 4 1.6GHz and 2GHz sold at different price while it is produced on the same wafer (hope someone tell you before). If intel sell at the same price, who want a 1.6GHz? People is greedy, and greedy make people suffer. If you are too greedy, you suffer, if I am too greedy, I suffer. Sometime you can always buy a 1.6Ghz and over clock to 2.0GHz, don't you? If you don't know how, please trust intel. intel promise you a 2GHz and won't give you a thing that only work at 1.6GHz.

RM139. AGD1 by Sanyo must be still able to be charged to ensure it can be refilled. Success rate~80% for this model.

Recieved, don't worry, this model can be done.

TwinHead mostly can(>98%)... RM179


Only 6 cells, 3 and 9 are not adequate. Mostly can(>90%)... RM179
