Safe battery handling

Large dc voltages are more dangerous than similar ac voltages

Only trained competent people should handle large batteries. (large is anything difficult to pick up with one hand). A single battery is designed to provide huge reserves of power and a spanner across the terminals will usually spit metal and then heat up the spanner!

Special attention must be paid when working on long `strings' of batteries which provide several opportunities for DANGER

if precautions are ignored. A string of batteries becomes more and more dangerous as the number of cells is increased. Voltages greater than 40 should be considered lethal.

Battery String Handling Do's + Don'ts

DON'Ts

DO's

NEVER SHORT CIRCUIT A BATTERY THEY ARE ALWAYS LIVE AND CAN EXPLODE.

Unlike AC high dc voltages will clamp you to the source and cause massive muscle contraction. At best you will end up with burns and broken bones at worst your heart will stop.
