Batteries
Need to replace two of my six 6v house batteries. The two were installed in 1999. The other four were installed in 2001.
Told that I should replace all six at the same time.
Reason given was that if any of the four not replaced are low they will tend to draw power from the new ones and thus lessen the life of the new ones.
Thoughts please!
Also, what is the difference between using three 12v batteries vs six 6v?
