I wanted a battery to retrieve data from my mother's laptop, so I wanted a cheap one, and I didn't mind that the warranty was only for a month. Hence I bought it from storebattery.com.au. When it arrived I plugged it in and tried to make sure it was charged. However the charging light didn't go on. So I turned on the machine and was able to download the data. I checked out the story on chargers and it seemed the laptop should work without the battery if the charger is connected. But it didn't. Hence the issue wasn't with the battery but with the charger! So glad I didn't go to the expense of buying a brand new battery. I note that the one from storebattery.com.au charges well. Chances are it will last longer than a month!
