Review on NinjaBatt'S Longlasting Battery Upgrade For Apple MacBook Pro 15" [2011-2012 Models Only] A1286/A1382 - 10.95V/77.5Wh by Dave Willis

The replacement battery for an Apple MacBook Pro 15” Mid 2012 seemed promising against its competitors. But it failed twice during the battery conditioning process. I wanted to try it to again with a return and replacement but there was no replacement available at the time. I chose to go with the runner-up competitor which had an available replacement. It survived the rigorous conditioning procedure and continues to perform faultlessly.
