IBM 08K8194 Battery are made from a grade cells and highest quality parts, the IBM laptop battery are tailored made according to the original size, whether the battery appearance, size and quality are the same as with the original. Every laptop battery should be under strict quality control including filtration and safety testing of voltage,capacity and battery core before leaving the factory, and has passed the authentication of CE, UL, EMC, CQC,ROHS, etc.
This is a late review as I have been using the battery for 2 1/2 years and it still retains +/- 90% of it's original life. I'll buy another as soon as this one dies.
This was the perfect fit for my laptop and so far I am very pleased with it.Thanks.
