Connecting batteries:
NOTE: The maximum number that can be connected in parallel is 4. In series, there are no limitations.
IN SERIES
By connecting the batteries in series you are doubling the voltage and maintaining the same capacity (amp hours). Connect the positive terminal of the first battery to the negative terminal of the second one. From the two free terminals connect the positive to the power lead on your device, and the negative to the ground connection of your application.
PARALLEL
By connecting the batteries in parallel you are doubling the capacity (amp hours) and maintaining the same voltage. Connect the positive terminal of the second battery to the positive terminal of the first battery. Do the same with the negative terminals. Connect your application to the positive and negative terminals of the first battery.
IMPORTANT INFORMATION BEFORE YOU BUY
To find the best replacement for your original battery you need to compare the physical dimensions, Volts, and Amp power of your original model to our battery. Besides physical dimensions, you also need to check battery terminals, which are the metal connectors on top of the battery. To determine what terminal your battery has, you will need to look at their form and determine if they have a flat connector, nut, and bolt, or wires, and then measure their sizes.
