Cutting the top off the motorcycle battery

We removed the top and cut through the heavy duty posts that connect the terminals to the plates.

The underside of the battery top

The inside of the battery top, this part was glued to the top of the battery casing and you can see the 2 heavy duty posts that attach to the positive (+) and negative (-) terminals, the 3 battery cell caps (for filling and topping up the battery) and the vent at the top of the picture.

Inside the battery lower casing

The internals of the 6 volt battery. In the bottom left of the pic you can see where the heavy duty posts attach connecting the plates to the terminals, also through the middle/top of the battery you can see how the plates in each cell are connected to each other.
This battery, being a 6 volt, has 3 cells, each cell should be capable of producing around 2.2 volts (which makes approx over 6 volts in total).

1 Of the 3 lead plates inside the battery

The insides of 1 of the battery cells. This were the lead plates from the end cell so you can see where the terminal posts would attach. You can also see in the top/center of the plates where they would be connected to the other 2 cells.
You can also see the bars across the center/top where the positive and negative plates are joined together.
