"Warp Factor Nine Scotty"
Now you know why Telecomm batteries don't come with a CA rating.
Plate warp
Some older wet batteries can be loaded and do the same thing. Four hundred and whoops...voltage drops to say 10.3 and stays there even when the load is relieved. When the grids cool down, boing, the needle jumps back up.
Not recommended...
Less amperage load or more batteries
Thought lifeline propaganda about -massive grids- was gobbledygook?
There are seemingly hundreds of ways a battery can act wierd this is one of them. Telecomm jar lightweight grid. Thick mat. Wonderful for intermittant moderate loads. But with a jeckyll & Hyde box of surprises for whom who ignores design specifications.
Caused by a grid component with a crack in it. Paste on the raw crack acts the part of conductive BONDO. Battery still works but too much overloading may make the grid element break permanent. Sounds like several breaks to me.
Throw another additional battery on line
