If smoke or dense vapor comes from the battery,
shut off the charger and reject the battery. If violent
gassing or spewing of electrolyte occurs, reduce or
temporarily halt the charging.
If the engine does not crank satisfactorily when a recharged
battery is installed, load test the battery as outlined under
TESTING. If the battery passes the "Load Test", the vehicle's
fuel, ignition, cranking and charging systems should be
checked to locate and correct the problem. If it does not pass
the load test, the battery should be replaced.
When an engine does not crank satisfactorily with a battery
which was not recharged before installation, recharge the
battery and subject it to the load test. If the battery fails,
replace it; if it tests satisfactorily and the engine still does not
crank satisfactorily check the vehicle systems mentioned
above to locate and correct the problem.
