How to charge/condition your new Acer TravelMate 290 Series battery

It is VERY IMPORTANT that you "condition" your new battery before you use it - you must understand that ALL new batteries behave erratically until they have been conditioned properly. Many people think there is a fault when they actually have a perfectly good battery which simply requires proper conditioning.

You will receive your Acer TravelMate 290 Series laptop battery fully discharged and unconditioned. If you turn on your Acer laptop, expecting it to work straight away you will be dissapointed. Your battery will normally take 3 or 4 charges to reach it's proper capacity and operation (sometimes more charges are needed) - until this time it is usual for it to perform strangely and hold only a little charge. Also, the LEDs and charge indicators on your charger and laptop will not give accurate information until the battery is fully conditioned - so dont take too much notice of what they do or dont indicate - just follow the instructions below.

On the first charge, your Acer laptop may indicate that charging is complete after a short period of around 15 mins. This is to be expected - simply remove the battery from your Acer TravelMate 290 Series laptop and repeat the charging procedure. You should then use your laptop - WITHOUT the assistance of mains power, until the battery completely runs down.

Repeat the above procedure around 4 times in total over the course of the next few days - make sure you allow you battery sufficient time to get a full charge, normally an overnight charge will suffice.

When the battery is fully conditioned, the battery charge indiciators and LEDs on your laptop and charger will work reliably. Also - as the battery will be taking on much more charge, the total charge time will be longer.


Occasional Maintenance

Simply run your Acer TravelMate 290 Series until the battery is FULLY discharged and then fully charge again. After extended periods of non-use, you should do the same. Lots of little charges followed by partial dischrage will decrease the life, performance and capacity of your battery - but in reality, this is how laptops are usually used and this may be unavoidable.
