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

After I installed this battery, and completed it's initial charge, my computer would randomly lose power and shut down I double checked my connections to make sure that it was secure and it happened two more times after that. Now it's been about a month and the battery won't work. My charger shows its fully charged and my white power light keeps flashing. Double checked the connections again, but nothing. Switched back to my old battery and everything works fine.
