1. Rotate Your Battery:
If you have a large bank of batteries, rotate the batteries within the bank periodically. This is because towards the middle of the bank may not receive as good of charge as the ones in the outside. Rotating the batteries periodically will help balance this out.
2. Use Large Battery Interconnect Cables:
Using large battery interconnect cables reduces resistance and allows for even charging. I usually recommend a 4/0 size cable for 12v and 24v system. You can use 2/0 for 48v systems.
3. Charge Your Batteries Frequently:
Batteries should never be left uncharged for extended period out time. Be sure to leave your charging source on, allowing the batteries to continue to charge. Leaving batteries uncharged can cause serious damage to them.
4. Keep Your Batteries Clean:
Remove the clamps and clean away dirts and oxidation. A filthy battery connection will weaken the battery over time and leads to loss of energy.
5. Use only Distilled Water for Your Flooded Lead Acid Battery:
I strongly oppose the use of additives or electrolytes as they do more harm than good to the battery.
6. Secure Your Battery:
Make sure the battery battery sits correctly in the battery rack. If your battery is jiggling around, it could tip over.
7. Ensure that Your Charging Device Has Capacity to Fully Charge Your Battery:
Insufficient charging power can lessen the life span of your battery or even damage them.
