One of the failure modes of Lead-Acid batteries is that one or more cells can develop internal short circuit paths that result in varying amounts of self-discharge current. If your existing battery maintains its voltage above 12.5 Vdc for a week or more while sitting disconnected from anything else, it should be good.

Wiring batteries in parallel adds the amps, wiring in series adds the volts. Combinations of serial and parallel add both. For instance, 2 100Ah 12V batteries in parallel is 12V at 200Ah. Two in series is 24V at 100Ah. Two series strings in parallel is 24V at 200Ah. Generally speaking, the higher your voltage the smaller your wires can be.

In theory it is OK to connect them in parallel with two conditions: Each battery must be in a state where it can be voltage charged. This is fine for lead acid batteries unless they are very run down. Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged.

Learn MoreCheck your battery chemistries – Sealed Lead Acid batteries for example have different charge points than flooded lead acid units. This means that if recharging the two together, some batteries will never fully charge. The result here would be sulfation of those that never reach a full state of charge, reducing their lifespan.
Connecting 12V batteries in series will increase the voltage of the battery bank while keeping the amp-hour capacity the same. Connecting 12V batteries in parallel will increase the amp-hour capacity of the battery bank while keeping the voltage the same.
However, the voltage of each battery remains the same. Here's what you need to know about connecting batteries in parallel: When you connect batteries in parallel, you connect the positive terminal of one battery to the positive terminal of the other battery and the negative terminal of one battery to the negative terminal of the other battery.
This means that if you connect two 6-volt batteries in parallel, you get a 6-volt battery with twice the amp-hour capacity. If you connect two 12-volt batteries in parallel, you get a 12-volt battery with twice the amp-hour capacity. Use a multimeter to measure battery voltage Klein Tools 69149P Electrical Test Kit with Digital Multimeter,…
To connect batteries in parallel, you need to ensure that the batteries have the same voltage. For instance, if you choose 12v batteries, you should only connect 12v batteries. You should also make sure that the batteries have the same or compatible chemistry and an appropriate charge capacity.
for secondary (rechargeable) batteries – the stronger battery would charge the weaker one, draining itself and wasting energy. If you connect rechargeable batteries in parallel and one is discharged while the others are charged – the charged batteries will attempt to charge the discharged battery.
