|Hi Richard, it would help if you advised your location (e.g. city/state/country).|
Reason for this, the www is truly ww, and often items in the US cost far more than here in the UK. The links THX has given are for US suppliers.
When looking for such batteries, I compare both Amazon and ebay. Generally ebay is comes out best, with many choices, plus communication with the seller is very good, which is almost non-existent on Amazon.
The battery needs be correct for the make and model of the device concerned, obviously with same voltage, but with a higher wattage if available, plus two year guarantees can be generally found. Normally the original has 6 cells, and it is wise to stick with this, rather than other (12 cell?) versions.
If you have an original battery (maybe same on oem one) it will have the part number or numbers, which can be used to be sure an oem one is correct for the device.
Have never had a problem with the many oem ones I have purchased. They are probably from China. If they fail after a year or so, at the end of the day it is not a problem as they are so inexpensive.
Good Luck - Keep us posted.
