SAFETY RECOMMENDATIONS
:
All the recommendations contained in this document must be strictly applied in order to
ensure a safe and optimal use of the battery.
Misuse of the battery may lead it to overheat or ignite and cause serious injury. Make
sure to follow the safety rules listed below:
Never short circuit the battery terminals
Do not open the battery
Do not reverse the polarity
Do not disassemble the battery
Do not subject the battery to excessive mechanical stresses
Do not expose the battery to water or condensation
Do not place the battery on or near fires, or other high temperature locations (> 70°C).
Doing so may cause the battery to overheat or ignite. Using the battery in this manner
may also result in a loss of performance and a shortened life expectancy.
Immediately disconnect the battery if, during operation, battery emits an unusual smell,
feels hot, changes shape, or appears abnormal in any other way. Contact SUEX if any
of these problems are observed.
40 BATTERY STORAGE
Initial state of charge calculation
(1) The right level of charge must be defined by taking into account:
- The storage period
- The maximum consumption of electronic devices
- The self-discharge of the cells (the higher the state of charge, the higher the rate of the
self-discharge).
Depending on the storage duration, the Initial state of charge of batteries before storage
must be between 15% and 50% of initial capacity, which correspond to an OCV of:
- For 15%: 36.9 V
- For 50%: 38.2 V
If after storage, the battery voltage is low or even at 0V, the battery protection circuit has
probably gone into ‘sleep mode’.
In such a case, the battery must be charged up as soon as possible in order to avoid
the voltage of one or more cells to fall below a level where the cell may be damaged.
Therefore, try to wake up the battery with an appropriate charger.
If the battery doesn’t take the charge, the voltage of one or more cells has dropped
below a level where it is forbidden to recharge and where the electronics protects the
battery.(2) A minimum state of charge of 5% (corresponding to an OCV of 36.2) is
required at the end of the storage period to avoid any further ‘Overdischarge state’.
