What Happens When You Connect Two 9 Volt Batteries Together

Find a dead 9 volt battery.

What happens when you connect two 9 volt batteries together. 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. Check out the diagram for more info. Well by connecting batteries you can increase the voltage amperage or both.

A battery bank is the result of joining two or more batteries together for a single application. This happens because the batteries are arranged in a line and like water flowing through different hoses connected in a line what goes in one end must come out the other. I wanted to see how many it would take before I get a shock.

Tear its head off - aka remove the terminals. If the batteries were connected in parallel both ends together and both - ends together then youd have a overall battery that can do 15 V at 2 A. All of them will reach the end of bulk charging together when theyve all reached the same voltage remember theyre connected togetherthey.

I start connecting them all together. The remaining unconnected battery ends are the ends of the overall 18 V battery. I had about 13 of em and felt a little tingle.

When you connect two or more batteries that dont charge and discharge at the same rate one battery will probably end up overcharged andor one battery will end up undercharged. In short connecting batteries of different voltages in series will work but damage will be done to both batteries during the discharge and recharge cycles. Note the blue wire designated W1.

In Figure 9 we see a pair of 12-volt batteries connected in parallel. You connect the end of one battery to the - end of the other. Making your own conector.
