Laptop Battery

Hi,

I purchased a laptop last year with battery that lasted for over 2 hours. However, recently it is only lasting for about 30 minutes. Rather than forking out £120 for a new battery, is there some way I can 'condition' my current battery.

All suggestions appreciated.

Many Thanks

James

Anyone got any ideas?

You probably need to "flatten" the battery every few charges or so - that's the reason my mobile phone battery is still going strong after four years and constant use.

But, if you do need to get a new one eventually, these outlets specialise at good prices:

Have you tried fully discharging it before a recharge?

Also is it kept permanently plugged in?

I've read that the pack can be rebuilt by specialist companies but I don't know of one or the cost.

What type of battery is it?; Nicad, NiMh, or Li-ion.

What notebook do you have?. Often good replacement batteries can be obtained from cheaper sources than the manufacturer.

Thanks for all your replies.

The battery is an Li-ion.

The manufacturer is Ei System, I have rung the helpline provided (Advent) they have batteries for it at £123.99.

I used to have the laptop plugged in on mains almost permanently, until recently when I decided to remove the battery when on mains (a bit late really!)

Is there anyway to condition the battery?

Many Thanks

I don't think so but I'd be interested if it were possible. My 2 year old battery on my laptop now last 10 minutes, mainly down to me keeping it permanently plugged in.

I am just discharging the laptop, but I've noticed that it is saying 7% remaining(1 min) but it's been saying this for about 20 minutes.

Anyone got any ideas on what is going on?

Regards

I think that the battery has given up the ghost. Have a look on eBay.

I agree with AubreyS; it sounds that the battery is on its way out.

I read this here about Li-ion batteries:-

"Is the Li-ion a better choice? Yes, for many applications. The Li-ion is a low maintenance battery which offers high energy, is lightweight and does not require periodic full discharge. No trickle charge is applied once the battery reaches full charge. The Li-ion battery can stay in most chargers until used. The charging process of a Li-ion is, in many ways, simpler and cleaner than that of nickel-based systems, but requires tighter tolerances. Repeated insertion into the charger or cradle does not affect the battery by inducing overcharge.

On the negative side, the Li-ion gradually loses charge acceptance as part of aging, even if not used. For this reason, Li-ion batteries should not be stored for long periods of time but be rotated like perishable food. The buyer should be aware of the manufacturing date when purchasing a replacement battery. Up to 1000 charge/discharge cycles can be expected if used within the expected service life of about two to three years.

Because of the aging effect, the Li-ion does not provide an economical solution for the occasional user. If the Li-ion is the only battery choice and the equipment is seldom used, the battery should be removed from the equipment and stored in a cool place, preferably only partially charged".
