My Macbook Pro 13inch 2011(A1276) new battery acting very weird(capacity/health decreasing quickly, slow charging and etc.). Battery has made only 10 charging cycles. I tried to reset SMC multiple times but the issue remained. Before contacting battery warranty service I want to know if it's a battery or a computer problem. I have an idea to test this battery on other Macbook Pro but different model(15 inch 2011 A1286). Connector of both batteries(A1322 and A1382) looks the same, voltage also the same - 10.95V. Can I do this without damaging computer?
