Let say I have a battery that is a few years old.
When it was new, the specific gravity was indicating 1.265 when full, and it lasted fairly long.
If I do an equalization charge, for the same battery after 7-8 years, what would I expect to see?
- The specific gravity when fully charged will rise to the same level but it won't last as long.
- The specific gravity when fully charged will indicate degradation of the battery and will show a lower level (say - 1.215 or so).
Which of these answers is more accurate?
