MACBOOK PRO 15' 2011 BATTERY IN BHARUCH

Selling my old MacBook Pro 15' battery. The battery is 3rd party. My MBP is one of the notorious MBP 2011 cases. This is the replacement battery which came after the first battery was returned within 1 year of warranty. I had purchased a 3rd party battery after my original one went kaput. That new battery lasted for 8-9 months and started giving me less backup which was due to a faulty voltage connection and frequent power downs at my campus. So, then I got a spikeguard and a new replacement battery. This combination worked fine until my MacBook went dead. Since then this battery has been lying around. I would like to give it up, rather than sitting in a dead MacBook and being wasted. This battery used to give me 3-4 hours of backup and has very few cycles. Most probably under 80-100 cycles. The brand is 4D.
