It's not just batteries that have changed, but also chargers.
Check out this early GE unit.

The 1914 Detroit Electric featured 68 batteries and had a range between 50 and 85 miles.  Cost new, $2,500.

This pump was built on September 22, 1930.  By the late 1920s, electric meter-type pumps were rapidly replacing the visible-register models.  Loosely known as clock-face pumps.  Remember, you don't need no stinkin gas.  EV4U can show you how to stop using gas.  www.EV4Unow.com

This is an example of a visible pump that was built in 1924.  These pumps first appeared around 1915.  Gasoline was pumped from underground tanks into a visible glass cylinder above the pump.  The operator watched the level of gas in the cylinder and stopped the flow when the gas reached the desired amount.
