If you connect two lead acid batteries together for loads only (somewhat difficult to achieve), the battery with the greater charge will try to charge the lower one. However, they will eventually stay equal but this will not last.
Connecting batteries in series means to connect the positive terminal of the first battery to the negative terminal of the second battery and so on down the string. The interconnecting cables must have equal lengths and resistance to equalize of the load.
Place the batteries close to each other to minimize the length of the connecting cables. Connect the positive terminals: Using the connecting cables, attach one end to the positive terminal (+) of the first battery and the other end to the positive terminal (+) of the second battery.
Always read and follow the recommended guidelines for your application. Never use two different chemistries when connecting multiple batteries together. For example, never connect an AGM battery with a flooded battery. This is because the voltages of the two batteries will be different.
Despite being three years old, the 160AH lead acid battery in this setup is still functional. It is currently hooked up to a 1KW inverter and helps power my house partially during power outages.
You can use both batteries at once according to the setting. When you have an outage, you can drain one battery and then switch to use the other battery. However, it is unclear if draining the batteries together using the inverter is bad for their health.
