JHL90 and battery charging problems, but only with new batteries!

I have a JHL90 that charges the original battery ok but the battery only lasts for about 10-15 minutes.

I got another battery but when I put it on charge the LED blinks orange instead of blue and stops charging. I tried a second battery and it was the same, orange blinking light. I got a third battery from a different source and still it refuses to charge showing the orange blinking light.

How come the original battery charges ok showing a blue blinking light but all 3 replacement batteries will not charge, any ideas?

 

fake batteries perhaps? or completely dead.

 

I actually have this problem too the last 2 months, since I have Windows 7 x64. It shows as fully charged and then it is all empty after 10 mins.

While I rarely use the battery, I am most times plugged in so it can't be the battery. When I plugged in my old hard drive with 32 bit XP on it, the battery works for hours.

It is a Windows 7 (only x64?) problem I think.

 

I am having the same issue with Windows 7 x64. I know this thread is old, so hopefully a fix has been found

 

Are you sure it works with XP?

It is not uncommon that a battery shows 100%, then falls off rapidly, or even shuts down the system - the reason is a bad cell.

I would try to run maybe Ubuntu from a USB stick - the process is very easy. Check how it is there, to rule out that the battery maybe has a defect.

If it runs "long" on Ubuntu, I would see if you have SmartBattery installed. I only know that from FL90 - no idea it is available for JHL9. If you run it, disable it, if you do not have it, try to get it - sorry that I cannot be of more help.

Cheers

 

resurrecting this thread once again lol....
I tried Ubuntu from a thumb drive and sure enough the battery died just as quick. Here is what I don't understand though:
The battery shows fully charged and the jumps straight to less than 10% this was both Windows and Linux.
Also,
Every program I've tried (SIW, HWMonitor, etc.) shows my battery as being in perfect condition Any ideas why?
Thanks!

 

I am not into how these things work in detail - I only know I had this problems already before, even with a new battery.

Loaded to 100%, went well to exactly 50%, when it went straight dead.

This is due to a dead cell, as far as I know - again, I cannot tell you why it then says 100% charged or why your tools claim AOK.

Either way, you need to get a new one ...

When you charge a battery, and it stops taking charge, it is assumed to be at 100%. This is very rarely the case. If the charger told the truth, then after a year it would be impossible to charge your battery to over 80%, since lithium batteries lose 20% of their charge capacity in the first year.

When the charge state is negative, you are discharging your battery. A voltage is then used from the cells to determine how much charge is left. Batteries containing bad cells will immediately show far less voltage than they should. Dropping down to 10% tells me you have more than one bad cell in the battery - in fact it could be 2 or 3 bad cells in there.

I question the battery itself. I believe that modern laptop batteries have some circuitry in them that aids the system in determining their actual charge capacity, against their stated charge capacity. Quite simply you're down to four possibilities here that I can see...
1 - User error - possibly you don't know how to interpret the results you're getting.
2 - Software error - possibly the software just isn't compatible with your system, and is giving false results
3 - The battery is a fake, and has been engineered to report everything is ok regardless - ie. doesn't monitor the cells at all.
4 - You're using the wrong replacement battery, which although it fits, is not compatible.

From what you're saying, I believe 3 is the most likely, and if so may actually be dangerous. You should be returning the battery as faulty, and getting a refund, if you can. Try a battery from a different supplier.
