      11. Appendix

      11.1 Instructions for use and safety procedures

      11.1.1 Recommended use

      read the instruction manual and the surface of the battery carefully, before using the battery,

      Please use the battery in normal indoor environment, temperature: 20±5°C, relative humidity: 65±20%

      Keep away from heat and high pressure, avoid children playing with batteries, and do not beat the battery during use.

      The battery can only be charged using the accessory charger. Do not put the battery in the charger for more than 24 hours.

      Do not short-circuit the positive and negative terminals of the battery. Do not disassemble the battery yourself. Do not place the battery in a damp place to avoid danger.

      When the battery is not used for a long period of time, please keep the battery in good condition and leave the battery in a half of SOC. Recharge it every 6 months. Do not wrap the battery with conductive material to avoid direct metal contact with the battery and damage the battery. Store the battery in a cool, dry place.

      Dispose of the battery safely and properly. Do not put it into fire or water.

      Danger warning

      Do not disassemble and assemble battery: Inside the battery has a protection mechanism and protection circuit to avoid danger. Inappropriate disassembly will damage the protective function and cause the battery to heat, smoke, deform or burn

      Do not short-circuit the battery: Do not connect the positive and negative terminals of the battery with metal. Do not store and move the battery together with the metal sheet. If the battery is short-circuited, excessive current will flow through it, which will damage the battery and cause the battery to heat, smoke, deform or burn.

      It is forbidden to heat and incinerate the battery: heating and incineration of the battery will cause the battery separator to melt, lose safety function or electrolyte burning, and the overheat will cause the battery to generate heat, smoke, deformation or burning.

      Avoid using the battery near the heat source: Do not use the battery in the vicinity of the fire source, the oven, or in excess of 80°C. Overheating will cause short circuit in the battery, causing the battery to generate heat, smoke, and deformation or burning.

      Do not get wet the battery: Do not get wet or put the battery into water. Otherwise it will cause the internal protection circuit and function of the battery to be lost and abnormal chemical reaction. The battery may have heat, smoke, deformation or burning.

      Attention

      Note: avoid using batteries in strong sunlight and exposure to avoid heat, smoke and deformation, at least avoid battery performance degradation and life expectancy reduction.

      Anti static: battery is equipped with protection circuit to avoid all kinds of accidents. Do not use the battery in the place where the static electricity is produced, because the static electricity is easy to damage the PCB, which causes the battery work to be abnormal, heat, smoke, deform or fire.

      Charging mode: please use special charger and recommended charging mode to recharge the battery under the recommended environmental conditions.

      Safe use protection: Please discuss with suppliers about the perfection of protection function, if battery is used for other equipment,.

      The battery should be charged immediately, When the battery pack is under voltage protection.

      Quality assessment

      Quality inspection is divided into appraisal inspection and quality consistency inspection. Appraisal inspections are generally conducted during the Design setting, change design and production setting. Sampling plans, inspection items, orders, and rules for determination are determined by both the supplier and the buyer. In principle, the above performance tests should be included. The quality consistency inspections are divided into batch inspections and periodic inspections to determine whether or not the products can be qualified in the production process to ensure the continued stability of product quality. Please refer to GB2828-1987 standard implementation. Inspection items shall include appearance, internal resistance, rated capacity or 1C5A discharge capacity, etc.
