Battery Protective Functions
The following protective functions are designed into the lithium-ion rechargeable
battery system used in FieldFox.
194
Lithium–ion batteries:
Must not be exposed to high temperatures (>70°C) or fire.
Must be kept away from children.
Must not be short circuited.
Must be replaced only with Keysight qualified Li–ion batteries.
If replaced or charged improperly, there is a danger of explosion.
Do not connect the positive terminal and negative terminal of the battery to each other with
any metal object (such as wire).
Do not carry or store the battery with necklaces, hairpins, or other metal objects.
Do not pierce the battery with nails, strike the battery with a hammer, step on the battery, or
otherwise subject it to strong impacts or shocks.
Do not solder directly onto the battery.
Do not expose the battery to water or salt water, or allow the battery to get wet.
Do not disassemble or modify the battery. The battery contains safety and protection devices,
which if damaged, may cause the battery to generate heat, explode, or ignite.
Do not place the battery in direct sunlight, or use or store the battery inside cars in hot
weather. Doing so may cause the battery to generate heat, explode, or ignite. Using the
battery in this manner may also result in a loss of performance and a shortened life
expectancy.
There is a danger of explosion if the battery is incorrectly replaced. Replace only with the
same or equivalent type of battery recommended. Discard used batteries according to
manufacturer's instructions.
If you are charging the batteries internally, even while the FieldFox is powered off, the
FieldFox may become warm. Allow for proper ventilation.
Do not discharge the battery using any device except the FieldFox or the external battery
charger (N9910X–872). When the battery is used in a device other than those specified, it
may damage the battery or reduce its life expectancy. If the device causes an abnormal
current to flow, it may cause the battery to become hot, explode, or ignite and cause serious
injury
