Fits my Lenovo W530 and performs as expected.
TL;DR- I recommend this battery Pros Sturdy, well built battery. (Depending on workload) Can give 5 hours of continuous power. Does not give any “Non- genuine” battery warning even on latest bios. Comes with usage instructions to prolong battery health . The windows command ‘powercfg /batteryreport /output’ gives a full charge capacity of 84,180 mWh which equates to 7794.4mAh which is basically 7800mAh. So the capacity is as advertised. Cons Makes the laptop quite heavy so if capacity is not what you are after then get the 6-cell instead.
I am very happy with the battery. It is working as expected. Definitely recommend.
Pros • Very long battery life • Clear instructions provided in the box on how to use and charge for the first time • Charges to 100 % • No problems with a non-Lenovo battery Cons • Protrusion from the back. Does not really bother me, as the results are spectacular
Good quality product not like some of the cheap and nasties from ebay. Gives me between 4-5 hours on full charge which is more than enough for me when on the road.
