Useless Sony batteries

gordonpearson — Tue, 16 Mar 2004 07:59:56 GMT

The battery on my Vaio notebook now lasts five minutes and while still showing 82% unused crashes even before the recorded announcement of low battery is completed. Is there any way of reviving batteries?

Time to buy a new battery I think.....

My old X9 showed that the battery had only done about 190 charge cycles but was dead after a few seconds when turning off the mains supply

The number of charge cycles shown is the number of FULL charge cycles (from empty to full). It does not register the number of partial charges.

Do The Batteries have a memory effect

Lithium Ion batteries should not have a memory effect, but that does not give them an infinate lifespan.

Steve's right, you need a new battery.
But if you're in your 12months of warranty, I'd speak to sony before laying out £80+

I think that you will find that batteries are only warranted for 90 days.......

On some systems, (like my old X9) when you look at the power profiles you can also look at the battery status, This will give you the current charge level. If there is a "ADVANCED" button, this will show you details about your battery, like the number of charge cycles, battery type, etc...

Hello everyone,

I read an article on notebook battery life("SVM" french magazine March 2004). They said every nobetook battery have 2 year to live.
Theire advert is :

Buy quickly as possible a new battery because later Sony battery price will be more expensive because our notebook will be older.

Sony, could you comfirm this information ?

Thank you

what i was told about batteries to increase their life:

1) Rechargeble battries are suposed to keep at least 85% of their capacity after 1 year of use. In fact we should talk about Cycles.
2) Li-On and Li-Polymer batteries do not have a memory effect, but have less cycles of life. (Most of the Laptop batteries are actually Li-On).
3) If you want to keep your battery for a long time, you should take care of it:
- Do Not Use when its not needed (and keep it charged)!
- Many people keep their battery constantly in their laptop, event if they are working on their desk with a power supply. If you use a power supply, you should un-mount your battery as soon as it is 100% charged, and keep it in a "safe" place (around 25°C).
- When you want to use your laptop on travelling, mount your battery again in your laptop.
- If you do not use your laptop while traveling very often, remember to recharge your battery once a month, because batteries have a "self discharge" rate.

I you want to have more autonomy you can of course:
- lower the brightness of the sreen
- Avoid use of CD/DVD and even your Hard dive (don't think that watching a movie on HD use less power than on DVD...)
- Buy a Centrino.....

See you

Antoine,

I thought I would reply to you here rather than PM, as I think it's important everyone seens my response.

All batteries are different, so this 2 years business from SVM magazine is a bit exagerated. I would say that's the AVERAGE, but some notebook batteries have lasted >5yrs. I do agree with SVM that buying a battery might be a sound investiment for the future, and you should consider it if you have spare cash.

Interesting to learn of other people's battery problems. My Vaio has deciced to stop charging altogether, although it still works on mains. I asked Sony what I should do - answer "buy another battery" - obvious really. I now have two batteries that won't charge !! Anyone got any bright idea's ( other than buy an abacus) how to get the damn thing to charge ?? - IAN

You may have some problems with your charging device IN your laptop, but before sending back your vaio to sony, check these quind of things:

- What does your vaio show about your battery? 0% charged? or 100% ???
- Is the charging Led "on", when trying to charge the battery?
- Are the battery/ charger contactors "Clean" (must be checked on the old battery), you may have dust, oxydation...

Just browsing through.. i dontknow if anyone will answer to that or if Tarik is still around...

i have the same problem with two batteries.
Mine shows 100% charging on both, and will die as soon as i get off the mains..

Charging LED is off, but then because the pc reports it being >85%, the manual says its normal to be off...

i have no idea, anyone help?

It's a long time since I have seen this thread, but it doesn't seem to be a common problem.

Re: Useless Sony batteries

Munzab — Fri, 15 Apr 2005 19:12:46 GMT

well ,the reason i have a pcg-sr series one is for portability.

im a student and im the hospital library all the time. With all the textbooks, lugging a desktop in my back is not really recommended healthwise

thats why battery life is important, while im in lectures (instead of dozing), i could be able to surf or type my projects using the battery...
