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 YAESU USA)

approved charger. The use of any other charger may cause perma-
nent 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.
