- Li-Ion cells are sensitive to mechanical damage. This kind of damage may cause its permanent dam-
age and thus - ignition or explosion. Any interference in the structure of Li-ion battery pack may cause
its damage. This may result in the ignition or explosion. A short-circuit of the battery poles "+" and "-"
may permanently damage the battery pack or even cause its fire or explosion.
- Do not immerse Li-Ion battery in liquids and do not store in humid conditions.
- If the electrolyte contained in the Lithium-Ion battery pack, contacts eyes or skin, immediately rinse the
affected place with plenty of water and consult a doctor. Protect the battery against unauthorised per-
sons and children.
- When you notice any changes in the Lithium-Ion battery pack (e.g. changes in colour, swelling, exces-
sive temperature), stop using the battery pack. Li-Ion batteries that are mechanically damaged, over-
charged or excessively discharged are not suitable for use.
- Any misuse of the battery may cause its permanent damage. This may result in the ignition. The seller
and the manufacturer shall not be liable for any damages resulting from improper handling Li-Ion battery
pack.
7.6 General principles for using gel (lead) rechargeable batteries
- Store the rechargeable batteries in a dry, cool and well ventilated place and protect them from direct
sunlight. Do not install them in a tightly closed container. While charging the batteries may produce
flammable gases, which may be the cause of explosion if proper ventilation is not available. The best
temperature for battery storage and operation is between 15°C and 25°C.
- Do not place batteries near equipment generating sparks, or store them in dusty areas.
- Do not connect the battery to any plastic elements or housing elements containing solvents. This may
cause the battery body to unseal or crack.
- During storage of lead batteries they are self-discharged. The storage time without charging is depend-
ent on ambient temperature: from 6 months at 20 °C to 2 months at 40 °C. In order to prevent excessive
battery discharge, resulting in a significant reduction of their capacity and durability it is required to
recharge them in specified intervals.
- Do not discharge the battery to a voltage below that, specified by its manufacturer. An attempt to
recharge an over-discharged battery may cause a thermal hazard, which results in battery deformation
or in change of the structure and distribution of the electrolyte in the battery as some of the water evap-
orates. This worsens the battery parameters similar to prolonged overcharging. Always recharge the
battery immediately after discharging, even if it was not discharged to the recommended cut off voltage.
Leaving a discharged battery for a couple of hours (sometimes even less than that if the discharge was
very deep) will cause sulphating.
- Charging may only be performed using a charger with specific parameters and under the conditions
set by their manufacturers. Failure to meet these conditions can lead to leakage, overheating or even
an explosion.
