About two and a half years ago I replaced my original flooded lead acid battery
pack (US2200XC) with lithium cells and re-tasked my flooded lead acid batteries
to solar backup for my house. Now almost five years out four of the twenty
four original batteries in the house backup have failed. I reconfigured the
pack and can live with the reduced capacity for a while. But I would like to
add the capacity back.
Options:
1. Replace the four bad batteries with four new batteries of the same type and
rated capacity as the original.
2. Replace the four bad batteries with four new batteries of capacity roughly
60% of the original (trying to match what I think the current capacity of the
original batteries).
3. Spend $2-$5K on a new pack.
Thoughts?
4. Go to a golf cart service business, and get four good USED golf cart
batteries. The cart business commonly replaces the batteries every few
years, whether they need it or not. They usually can't/won't bother to
check them, and this is the cheapest way to do it.
The used batteries will be a much better match for your present used
batteries, and so easier to keep healthy and in balance in their
declining years.
