3Ah NiMH AA-size battery problem?
High performance so not thrown away lightly
No difference in observed powering performance to its mate bought at the same time. Same DVM loaded battery test after both are charged. Orange MP make if relevant. One has had for some time , ignored as a scuff mark to the orange plastic and apparently showing aluminium case under, a hole in the case. About 2 x 1 mm looks like a melted oval rim of aluminium with central area of dusty grey ceramic looking material. But the surrounding orange heatshrink is not melted , looks a neat junction between oval "cut" plastic and melted aluminium which makes no sense. What is this hole? prognosis? paliative measures to be taken ? dangerous chemically or flammability ? |
