- Page 34 Before cleaning or performing maintenance tasks, disconnect the SUNSYNK-W10.6 Li-Ion battery from ƒ all loads and charging devices. Use the enclosed protective caps on terminals during these activities to avoid terminal contact risks. Inspection Inspect the wiring and contacts for looseness or damage, including cracks, deformations, leaks, or any other type of damage. If any damage is found, replace the battery immediately. Do not attempt to charge or use damaged batteries under any circumstances. ƒ IMPORTANT: Avoid contact with liquid from a ruptured battery. Regularly monitor the battery's state of charge. Lithium Iron Phosphate batteries gradually discharge when not in use or during storage. Consider replacing the battery if you notice either of the following conditions: 1. The battery's run time decreases below 70% of the original run time. 2. The battery's charge time significantly increases. Cleaning If cleaning is required, use a soft, dry cloth to clean the Li-Ion battery. Avoid using liquids, solvents, or abra- sives for cleaning purposes. Maintenance The Li-Ion battery is maintenance-free. Charge the battery to approximately over 80% of its capacity at least once every year to maintain its capacity. Storage The battery product should be stored in a dry and cool environment. Typically, the maximum storage period at room temperature is six months. If storing the battery for over six months, it's recommended to check the battery voltage. If the voltage exceeds 51.2V, you can continue storing the battery. However, it's important to check the voltage at least once a month until it drops below 51.2V. Once the voltage is lower than 51.2V, charge the battery according to the following strategy: 1. Discharge the battery to the cut-off voltage using a 0.2C (40A) current. 2. Charge the battery with a 0.2C (40A) current for approximately 3 hours. 3. Maintain the State of Charge (SOC) of the battery at 40%-60% during storage. When storing the battery, ensure it's kept away from explosive and flammable areas, and keep ignition sources and high temperatures distant from the battery. SUNSYNK-W10.6 | User Manual...

- Page 36 80%. Here are the steps involved in the process: Recovery Process and Steps of Cathode Materials Aluminium foil, being an amphoteric metal, is dissolved in a NaOH alkali solution to form NaAlO , which enters the solution. After filtration, the filtrate is neutralized with sulphuric acid and precipitated to obtain Al(OH) . When the pH is above 9.0, most of the aluminium precipitates, and the obtained Al(OH) achieves chemical purity after analysis. The filter residue is dissolved with sulphuric acid and hydrogen peroxide. This process allows lithium iron phosphate to enter the solution in the form of Fe and Li , separating it from carbon black and carbon coating on the lithium iron phosphate surface. After filtration and separation, the pH of the filtrate is adjusted with NaOH and ammonia water. Iron is first precipitated with Fe(OH) , and then the remaining solution is precipitated with saturated Na solution at 90ºC. Since FePO is slightly soluble in nitric acid, the filter residue is dissolved with nitric acid and hydrogen perox- ide. This process directly precipitates FePO and separates impurities like carbon black from the acid solu- tion. It also leaches Fe(OH) from the filter residue and precipitates Li with saturated Na solution at 90ºC. Recovery of Anode Materials The recovery process for anode materials is relatively straightforward. Following the separation of the anode plates, the purity of copper can exceed 99%. This high-purity copper can then undergo further refining to produce electrolytic copper. Recovery of Diaphragm The diaphragm material is mainly harmless and has no recycling value.

- Page 37 TRANSPORTATION REQUIREMENTS Transport battery products immediately after packaging using cars, trains, or ships. During transportation, avoid exposing the packaging to severe vibration, impact, or compression, as well as direct sunlight or rain. Always ensure compliance with local, national, and international regulations before transporting Lithium Iron Phosphate batteries. Note that the transport of end-of-life, damaged, or recalled batteries may be restricted or prohibited in some cases. The transport of Li-Ion batteries is classified under hazard class UN3480, class 9, falling into packaging group PI965 Section I for transport by water, air, or land. For transportation of lithium-ion batteries assigned to Class 9, use Class 9 Miscellaneous Dangerous Goods and UN Identification labels.
