Specific Warnings and Cautions regarding batteries while being discharged.
Warning
Do not discharge the battery using any device except the PSLV . When the
battery is used in devices aside from the PSLV , 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, breakage 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.
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 PSLV 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 PSLV 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, you should not use the PSLV
in freezing temperatures with a battery charge indication of 50% or less.
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.
Caution
Immediately discontinue use of the battery if while using, charging, or storing the
battery, the battery emits an unusual smell, feels hot, changes color, changes shape, or
appears abnormal in any other way. Contact OSS if any of these problems are observed.
