Another consideration is the potential failure of the charger. If
the charger malfunctions, causing higher-than-recommended
charge rates, substantial volumes of hydrogen and oxygen will
be vented from the cell. This mixture is explosive and should
not be allowed to accumulate. Therefore, despite its significant
advantages over other lead-acid batteries, the CYCLON
batteries SHOULD NEVER BE CHARGED IN A GAS-TIGHT
CONTAINER.
8.3 Shorting
CYCLON batteries have very low internal impedance and
thus are capable of delivering high currents if externally short
circuited. The resultant heat can cause severe burns and is a

potential fire hazard. Particular caution should be used when
the person working near the open terminals of cells or batteries
is wearing metal rings or watchbands.
Accidentally placing metal articles across the terminals could
result in severe skin burns. It is a good practice to remove all
metallic items such as watches, bracelets and personal jewelry
when working on or around battery terminals.
As a further precaution, when installing batteries or working on
them, insulating gloves should be worn and only insulated tools
should be used to prevent accidental short circuits.
