Group 58R Battery Dimensions
Battery of this group has the positive post terminal located on the right. It is marked with the letter "R" because this post terminal position is called Reverse Polarity of Battery. Most batteries have it on the left side. If you want the positive post terminal to be on the left, you can turn around the 58R battery and use it as a group 58 battery, because they have identical dimensions. This will allow you to use the positive post on the left. Make sure you have enough cable length to reach the terminals, because in the turned position the terminals can be located a little further.

How to Get 24 Volts from 12V of a 58R Battery Group
If you need 24 Volts, you can connect two group 58R batteries in series to double the voltage. The voltage of a series connection is equal to the sum of the voltages of all its batteries. If one 12V lead-acid battery is connected to another 12V lead-acid battery, you have 24V total power output. Each battery must be fully charged and completely isolated from the other before connecting them in series, or there will be damage to at least one of them.
Increasing a Capacity of 58R Batteries with a Parallel Connection
If you need to increase current capacity and reduce charging time, connect batteries in parallel. When group 58R batteries are in parallel, their voltage is equal to the voltage of one battery, while current capacity equals to the sum of all its battery capacities. If you have two 12V lead-acid batteries with 60 Ah capacity and you connect them in parallel, you'll get 12 Volts with 120 Ah.
