If your battery charger produces a charge rate greater than 12 volts it may damage your batteries. The basic concept is that when connecting in parallel you add the amp hour ratings of the batteries together but the voltage remains the same.

Connecting batteries in parallel to charge. The diodes effectively block the inter links between the batteries preventing any possibility of cross discharge yet allows them to charge from a common source and discharge uniformly across a common load. Put your 12v vehicle battery back into your vehicle and link it once again now you. The more batteries connected in parallel the longer the charge will take. A battery word equation and special note. Twelve volt batteries wired in parallel must be charged at 12 volts. 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.
The battery reconditioning station. The shown method of connecting batteries in parallel without cross discharge is very simple and involves the use a few diodes. Beams will put your battery under load. Want to place on your high beams do not begin the cars and truck engine the high. Series connection increases battery voltageparellel connection increases battery capacity. Connect the negative black wire from your battery charger to the negative terminal of one of the 12 volt batteries wired in parallel.
How to connect lithium batteries in parallel and series. The negative terminal is labeled. Two 6 volt 45 ah batteries wired in parallel are capable of providing 6 volt 9 amp hours 45 ah 45 ah.
