There are 10 cells (2P5S pack), and theyre held together with rather substantial interconnect strips. Attempting to charge batteries outside the 40F-105F range can result in a permanent loss of run-time. All it will show you is a lagging reading of the temperature of the cells near it. So, theres no reason to rebuild it. When the positive terminal is made up of copper, the corrosion will have a bluish color or greenish color, or a mixture of both.
