3.0 Working with Batteries
Lead-acid batteries contain a sulfuric acid electrolyte, which is a highly
corrosive poison and will produce gasses when recharged and explode if
ignited. It can hurt you badly.
When working with batteries, make sure you have plenty of ventilation, remove
your hand jewelry, watch and wear protective eyewear (safety glasses),
clothing, and exercise caution.
Do not allow battery electrolyte to mix with salt water. Even small quantities of
this combination will produce chlorine gas that can KILL you!
Whenever possible, please follow the manufacturer's instructions for testing,
jumping, installing, charging and equalizing batteries.
Never disconnect a battery cable from a vehicle with the engine
running because the battery acts like a filter for the electrical
system.
Unfiltered [pulsating DC] electricity can damage expensive
electronic components, e.g., emissions computer, radio,
charging system, etc.
Turn off all electrical switches and components; turn off the
ignition before disconnecting the battery.
For non-sealed batteries, check the electrolyte level. Make sure it
is covering the plates, and it is not frozen before starting to
recharge (especially during winters).
Do not add distilled water if the electrolyte is covering the top of
the plates because during the recharging process, it will warm
and expand. After recharging has been completed, recheck the
level.
