Specific Warnings and Cautions regarding batteries while being discharged.
Warning
Do not discharge the battery using any device except the FRV. When the
battery is used in devices aside from the FRV, it may damage the performance of the
battery or reduce its life expectancy. If the device causes an abnormal current to flow, it
may cause the battery to become hot, rupture, or ignite and cause serious injury.
Caution
The temperature range over which the battery can be charged is 32 °F (0 °C)
to 114 °F (45 °C.) Charging outside of this range may cause excessive heating, break-
age or may reduce battery performance.
Caution
The temperature range over which the battery can be discharged is - 4 ° F
(-20 °C) to +140 °F (+60 °C .) Use of the battery outside of this temperature range may
damage the performance of the battery or may reduce its life expectancy.
Specific Warnings and Cautions regarding the charging of Lithium Ion batteries.
Warnings
•
When charging the battery, use only the specified charger supplied by OSS.
•
Do not attach the batteries to a power supply plug or directly to a car’s cigarette
lighter.
•
Do not place the batteries in or near fire, or into direct sunlight. When the battery
becomes hot, the built-in safety equipment is activated, preventing the battery
from
charging further. Heating the battery can destroy the safety equipment
and
cause additional heating, breaking, or ignition of the battery.
•
Do not continue charging the battery if it does not recharge within the specified
charging time of 4 to 8 hours. Doing so may cause the battery to become hot,
rupture and ignite.
LITHIUM ION BATTERY INFORMATION TO HELP PROLONG THE LIFE OF YOUR BATTERY
Since the battery pack will discharge over time in storage, it must be partially charged every few
months to extend cycle capacity or else it may fail to charge or hold power in the future. The battery is
best stored at charge levels between 20% through 80%. Do not allow the battery to remain in a fully
discharged state and do not continually charge the battery. Check the battery level after a dive trip. If
the level is 40% or more, put the FRV away. After 2 to 3 months of disuse, recharge the battery for an
hour and recheck that the charge level is between 40% and 80%—do not fully charge. Of course, the
day before a dive trip, always fully charge the battery.
The battery typically has a lifespan of between 300 and 500 cycles under normal usage and operating
conditions. Using the FRV in a higher or lower ambient temperature affects the total number of cycles
in the battery’s service life.
Lithium Ion batteries are less efficient with age and in near-freezing temperatures. Batteries age
naturally over time and will not retain as much energy. After several years, a normal battery may
have a decreased charge capacity of 60% of new. Additionally, Lithium Ion batteries do not perform
optimally at temperatures nearing freezing levels.
For both reasons listed above, we recommend
you do not use the FRV in freezing temperatures with a battery charge indication of 50% or
less.
DO
•
Store battery with a charge level between 20% and 80%
•
Partially charge the battery every 2 to 3 months.
