This method of charging batteries in parallel will result in each battery drawing the same amount of current from the charger. Two 12 volt batteries wired in parallel continue to produce 12 volts but the capacity doubles.
How To Connect Your Batteries To Make Up A 24v Or 48v System
Charging 2 batteries in parallel. On the other hand charging two identical batteries in series will not cause problems but you will need a 24 v charger. Two 12 volt batteries in parallel one 12 volt charger figure 9. Two batteries in parallel one charger batteries connected in series strings can also be recharged by a single charger having the same nominal charging voltage output as the nominal battery pack voltage.

It will maximize the lifespan of all your batteries as they will be charged and discharged evenly.
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. Determine the total voltage of the batteries. For example if charging one battery normally takes three hours and you have five batteries linked in parallel the charging time will be five times three hours or 15 hours. This method of charging can be utilized when there is an even number of batteries 4 6 8 etc. For secondary rechargeable batteries the stronger battery would charge the weaker one draining itself and wasting energy. Balanced chargingloading of 4 parallel 12v batteries duration.
When linked in series the voltages of the batteries are cumulative but the current remains the same. Complete off grid 12v dual battery masterclass pt 1 dual battery basics duration. Batteries may be wired in parallel or in series. Charging 12 volt batteries wired in parallel requires a 12 volt battery charger. For example if fast charging one battery usually takes about an hour or two than two batteries connected in parallel takes two to four hours. In figure 8 a single 24 volt charger is connected to a 24 volt battery pack.
Two 12 volt batteries wired in series produce 24 volts but the capacity remains the same as one for a 12 volt battery. The problem is that batteries are never quite identical so in parallel one battery will always charge better than the other causing the charger to think that both are fully charged when only one is. The more batteries connected in parallel the longer the charge will take. An example method of charging batteries in parallel is to use one branch of the parallel circuit to charge each battery with a single charger.
