Unlike wiring batteries in series when batteries are wired in parallel the voltage does not increase the output voltage is the average voltage of all batteries in the circuit. Following this example where there are two 12v 200ah batteries connected in series we will have a total voltage of 24v volts and an unchanged capacity of 200ah ampere hour.

3 batteries in series. If two 15 volt batteries were connected together the multimeter would show 3 volts. Battery technology has advanced dramatically since the days of the voltaic pile. This makes charging the battery difficult because the increases in voltage will provide different charges to each battery. The series connection of two identical batteries allows to get twice the rated voltage of the individual batteries keeping the same capacity. In contrast batteries connected in a parallel configuration are able to increase the amp hour capacity of your batteries at the same voltage. Hence when charging these batteries it is important to utilize a charger that satisfies the 12 volt capacity that is necessary for both the 6 volt batteries connected in series.
9 v with a center tap was available by wiring in series. There were two 32 mm negative pins spaced 95 mm apart and two 40 mm positive pins spaced 143 mm apart. Batteries in series or parallel are only recommend to be the same type so three 8v batteries are required for 24v system and if you wanted a series parallel setup for higher capacity you could get another 3 to put in parallel. If you have 3 batteries in parallel and force that through any in seriesthe series batteries will either restrict the maximum current flow or worseyou could be charging the series batteries which could cause them to failleakexplode. 524 this battery contained two independent 45 v batteries and had a four pin connector. For example if a 3v and a 9v battery were wired in parallel the output voltage would be 6v 93 divided by 2 however the current will be total amperage of all.
In theory a 6 volt 3 ah battery and a 6 volt 5 ah battery connected in series would give a supply of 12 volts 3 ahthe capacity of the weaker battery always restricts the circuit and if you did so it would work and nothing would explode to start with. Connect the negative lead from the multimeter to the negative terminal on the second battery. The four batteries in parallel arrangement will produce 15 volts at 2000 milliamp hours. Its never a good idea to have any batteries in series with a parallel set. The multimeter display will show a total voltage equal to the sum of the voltage of both batteries. Imagine the batteries shown in the diagram are rated at 15 volts and 500 milliamp hours.
Repeat the process to add a third battery. The four batteries arranged in a series will produce 6 volts at 500 milliamp hours. When charging 3 12v batteries in series with one another each voltage of each battery would increase in an amount dictated by ohms law v ir for voltage v in volts current i in amperes and resistance r in ohms. Connecting batteries of different amp hour ratings in series. Negative and positive pins were spaced 181 mm apart.
