Battery Recommendations
• Batteries are shipped approximately 30% to 60% charged and should be fully
charged for maximum charge capacity.
• The battery is a lithium ion cell and can be used without a full charge, as well
as can be charged without fully discharging, without impacting the battery life.
There is no need to perform any charge/discharge conditioning on this cell
type battery.
• Do not disassemble the battery. There are no user-serviceable parts in the
battery.
• Keep the base connected to power when the host is not in use.
• Replace a defective battery immediately since it could damage the 3820.
• Don’t short-circuit a battery or throw it into a fire. It can explode and cause
severe personal injury.
• Although your battery can be recharged many times, it will eventually be
depleted. Replace it after the battery is unable to hold an adequate charge.
• If you are not sure if the battery or charger is working properly, send it to Hand
Held Products or an authorized Hand Held Products service center for
inspection.
Proper Disposal of the Battery
When the battery has reached the end of its useful life, the
battery should be disposed of by a qualified recycler or
hazardous materials handler. Do not incinerate the battery or
dispose of the battery with general waste materials. You may
send batteries to Hand Held Products (postage paid). The
shipper is responsible for complying with all federal, state, and
local laws and regulations related to the packing, labeling,
manifesting, and shipping of spent batteries. Contact the
Product Service Department (see 13-1) for recycling or disposal information.
Since you may find that your cost of returning the batteries significant, it may be
more cost effective to locate a local recycle/disposal company.
