CAUTION
Take care to avoid short-circuiting the battery. Use caution when working near
the open terminals or cells when wearing metal rings or watchbands.
Shorting results in dangerously high current flow that could cause severe
burns and is a potential fire hazard. Placing metal articles (such as rings or
watchbands) across shorted terminals could result in severe skin burns.
Handle the battery with utmost care to avoid the possibility of a short circuit.
