DO NOT INCINERATE: Do not dispose of any battery in a fire or incinerator.
The heat of fire may cause battery cells to explode and/or release dangerous
gases.
Battery Maintenance
For safe and proper battery use, please observe the following:
Battery packs should be charged only in non-hazardous environments;
Use only STANDARD HORIZON-approved batteries;
Use only a STANDARD HORIZON, (a Marine Division of VERTEX
STANDARD) approved charger. The use of any other charger may
cause permanent damage to the battery.
Follow charging instructions provided with the chargers.
Keep the battery contacts clean.
Battery Storage
Store the batteries in a cool place to maximize storage life. Since batteries are
subject to self-discharge, avoid high storage temperatures that cause large
self-discharge rates. After extended storage, a full recharge is recommended.
Battery Recycling
DO NOT PLACE USED BATTERIES IN YOUR REGULAR TRASH!
LI-ION BATTERIES MUST BE COLLECTED, RECYCLED OR DISPOSED
OF IN AN ENVIRONMENTALLY SOUND MANNER.
The incineration, land filling or mixing of Li-ion batteries with the municipal
solid waste stream is PROHIBITED BY LAW in most areas.
Return batteries to an approved Li-ion battery recycler. This may be where you
purchased the battery.
Contact your local waste management officials for other information regarding
the environmentally sound collection, recycling and disposal of Li-ion batteries.
