Battery Safety
WARNING: A battery can present a risk of electrical
shock or burn from large amounts of short-circuit
current, fire, or explosion from vented gases.
Observe proper precautions.
WARNING: Risk of Explosion.
Proper disposal of batteries is required. Do not
dispose of batteries in fire. Refer to local
regulations or codes for requirements.
CAUTION: The EcoBoost charging algorithm is not
suitable for lithium batteries. Use only lead-acid
batteries.
CAUTION: When replacing batteries, use properly
specified number, sizes, types, and ratings based on
application and system design.
CAUTION: Do not open or mutilate batteries.
Released electrolyte is harmful to skin, and may be
toxic.
NOTE: Although not anticipated, in the exceedingly
rare chance of component failure, there is a risk of
battery overcharging. Use of a voltage limiting device
can safeguard unattended systems against the
possibililty of such an occurrence.
