Can I add more batteries to my battery bank?
Expanding Your Battery Bank
When you add a new lead acid battery into an old bank, the new battery takes on the capacity and other characteristics of the existing batteries. When you add more batteries, they drain down to the level of the old ones. This might not be a big deal if the battery bank is only a year old.
