6. Inspection, Cleaning and Maintenance
6.1 General Information
The battery product is not fully charged. It is recommended that the installation be completed within 3 months after arrival;
During the maintenance process, do not re-install the battery in the battery product. Otherwise, the performance of the battery will be reduced;
It is forbidden to dismantle any battery in the battery product, and it is forbidden to dissect the battery;
After the battery product is over-discharged, it is recommended to charge the battery within 48 hours. The battery product can also be charged in parallel. After the battery product is connected in parallel, the charger only needs to connect the output port of any product battery.
Never attempt to open or dismantle the battery! The inside of the battery does not contain serviceable parts.
Disconnect the Li-Ion battery from all loads and charging devices before performing cleaning and maintenance activities
Place the enclosed protective caps over the terminals before cleaning and maintenance activities to avoid the risk of contacting the terminals.
6.2 Inspection
Inspect for loose and/or damaged wiring and contacts, cracks, deformations, leakage, or damage of any other kind. If damage to the battery is found, it must be replaced. Do not attempt to charge or use a damaged battery. Do not touch the liquid from a ruptured battery.
Regularly check the battery’s state of charge. Lithium Iron Phosphate batteries will slowly self-discharge when not in use or whilst in storage.
Consider replacing the battery with a new one if you note either of the following conditions:
– The battery run time drops below 70% of the original run time. – The battery charge time increases significantly.
6.3 Cleaning
If necessary, clean the Li-Ion battery with a soft, dry cloth. Never use liquids, solvents, or abrasives to clean the Li-Ion battery.
6.4 Maintenance
The Li-Ion battery is maintenance free. Charge the battery to approximately > 80% of its capacity at least once every year to preserve the battery’s capacity.
6.5 Storage
30

The battery product should be stored in a dry, cool, and cool environment; Generally, the maximum storage period at room temperature is 6 months. When the
battery is stored over 6 months, it is recommended to check the battery voltage. If the voltage is higher than 51.2V, it can continue to store the battery. In addition, it is needed to check the voltage at least once a month until the voltage is lower than 51.2V. When the voltage of the battery is lower than 51.2V, it must to be charged according to the charging strategy. The charging strategy is as follows: discharge the battery to the cutoff voltage with 0.2C(40A) current, and then charge with 0.2C(40A) current for about 3 hours. Keep the SOC of the battery at 40%-60% when stored; When the battery product is stored, the source of ignition or high temperature should be avoided and it should be kept away from explosive and flammable areas.

8. Battery recovery
Aluminum, copper, lithium, iron, and other metal materials are recovered from discarded LiFePO4 batteries by advanced hydrometallurgical process, and the comprehensive recovery efficiency can reach 80%. The specific process steps are as follows. 8.1 Recovery process and steps of cathode materials Aluminum foil as collector is amphoteric metal. Firstly, it is dissolved in NaOH alkali solution to make aluminum enter the solution in the form of NaAlO2. After filtration, the filtrate is neutralized with sulfuric acid solution and precipitated to obtain Al (OH)3. When the pH value is above 9.0, most of the aluminum precipitates, and the obtained Al (OH)3 can reach the level of chemical purity after analysis. The filter residue is dissolved with sulfuric acid and hydrogen peroxide, so that lithium iron phosphate enters the solution in the form of Fe2 (SO4) 3 and Li2SO4, and is separated from carbon black and carbon coated on the surface of lithium iron phosphate. After filtration and separation, the pH value of the filtrate is adjusted with NaOH and ammonia water. First, iron is precipitated with Fe (OH) 3, and the remaining solution is precipitated with saturated Na2CO3 solution at 90 . Since FePO4 is slightly dissolved in nitric acid, the filter residue is dissolved with nitric acid and hydrogen peroxide, which directly precipitates FePO4, separates impurities such as carbon black from acid solution, leaches Fe (OH) 3 from filter residue respectively, and precipitates Li2CO3 with saturated Na2CO3 solution at 90 . 8.2 Recovery of anode materials The recovery process of anode materials is relatively simple. After the separation of anode plates, the purity of copper can be more than 99%, which can be used for further refining electrolytic copper. 8.3 Recovery of diaphragm The diaphragm material is mainly harmless, and has no recycling value. 8.4 List of recycling equipment Automatic dismantling machine, pulverizes, wet gold pool, etc.
34

9. Transportation Requirements
The battery products should be transported after packaging and during the transportation process, severe vibration, impact, or extrusion should be prevented to prevent sun and rain. It can be transported using vehicles such as cars, trains, and ships. Always check all applicable local, national, and international regulations before transporting a Lithium Iron Phosphate battery. Transporting an end-of-life, damaged, or recalled battery may, in certain cases, be specially limited or prohibited. The transport of the Li-Ion battery falls under hazard class UN3480, class 9. For transport over water, air and land, the battery falls within packaging group PI965 Section I. Use Class 9 Miscellaneous Dangerous Goods and UN Identification labels for transportation of lithium-ion batteries which are assigned Class 9. Refer to relevant transportation documents.
