Replacement Battery for R40

[tomartom]

The battery is nearing death in my laptop only lasting for around 40 minutes. M processor, which should give at least 2 hours of service.

My question is What brand of cells do IBM use for their battery packs. The original battery is made in Taiwan. I have just ordered a replacement battery form IBM, rather than going with an aftermarket supplier as I have been advised that the cheaper packs use inferior cells. The model is 2722 C3M.

Many thanks

It is not necessarily the brand of cells that make aftermarket packs inferior... There are several factors... Too many too list... It is just worth spending the extra $ on an IBM battery...
