The rules for use and storage of batteries
Protect from improper handling.
Do not insert with opposite polarity, follow the signs. If the batteries are inserted in reverse, can cause a short-circuit or charging.
Prevent short-circuiting. If possitive (+) and negative (-) battery terminals are connected, short-circuiting happens.
Before installing, clean the terminals of battery and the terminals facilities.
The LiFePO4 should be always mounted with the terminals facing upwards.

Do not heat excessively. – batteries operate at temperatures according to the specifications.
Do not weld the cells.
Do not disassemble. When open may be contact with different parts of the battery harmful.
Do not distort. Batteries should not be compressed, punctured or damaged in any way.
Do not dispose of in fire.
Do not expose to water or excessive humidity.

Keep away from children. Beyond their reach, it is necessary first of all to keep away batteries which can be swallowed. In addition, children should not be allowed replacement of batteries without adult supervision.
Do not incase or modify. Any modifying of the battery may cause block safety ventilation mechanism. Any adjustments should consult the dealer.
Unused batteries should be stored charged and keep them away from metal subjects, which can make short-circuiting the battery. Alreary unpackage units should not be mixed and stored with unused batteries.
Avoid extreme humidity (over 95%) High temperature or humidity may worsening of battery characteristics and / or corrosion of the surface.
Do not storage / expose the battery to direct sunlight, in places where they may be exposed to rain, excessive heat such as radiators or heaters.
Batteries stored in well-ventilated and dry environment, ideally enclosed in a protective case.
During storage, keep the temperature within the range according to the specifications of a particular article.
Do not mix with other materials.
Do not stack cardboard box with batteries. When stacking may cause deformation of the battery in the lower layers and the subsequent flow of electrolyte.
For additional transportation / handling and packing materials, choose the method of packaging to prevent unintentional electrical contact and corrosion terminals, providing protection against environmental influences and mechanical damage.
Considerate handling of the boxes. Rough handling can cause a short circuit or damage.
Ensure proper circulation of stocks, follow FIFO system (First In, First Out).
Check the voltage of the cell every 2 month. Charge the cell if the voltage dropped to a minimum value of voltage

Battery operate under the supervision or constant monitoring protection and control systems. Protect against overcharge and deep-discharge.

Charging

WARNING: Carefully check the maximum voltage as specified cells or batteries. Exceeding the voltage will damage the battery and avoid the warranty.

Initial charging
New batteries LFP/LFYP are partly charged from factory. However, before first use it is absolutely necessary to charge the battery to full capacity. This initial charging should be done at maximum current of 1C and the voltage level according to the specification of the cell or battery. Please see specifications of the cell about value of initial charging. Battery capacity in the first cycle gradually grows. In the first few cycles is recommended to avoid rapid discharge to the minimum capacity and we do not recommend quick charging. After about the fifth, sixth cycle, is nothing to prevent the batteries used in full operating cycle according to the manufacturer's specifications for the type of battery.

Standard charging
Because LiFePO4 batteries has no memory effect, charging can be done at any time. Repeated short charge cycles the battery life not significantly changed (within + / - 5%).
