The photosynthesis apparatus and oxygen analyzer produced by our company use advanced "lithium ion rechargeable batteries". In order to effectively and safely use this type of battery, the relevant precautions are now provided as follows: 1. Storage of the battery: Remove the battery when the instrument is not used for a long time. When storing the battery, it should be done: ①charge the battery so that it reaches 7.8V ~ 7.9V (the nominal voltage of the battery is 7.4V) ② put it in a dry environment, the relative humidity of the air is ≤93%. ③ Do not get close to the heating device, keep the ambient temperature of the air around 25 ℃, and do not exceed 50 ℃. ④ It is best to charge the battery at least once every month. 2. Charging of the battery: The lithium battery used in our company's products is equipped with a special charger. When charging, please do: ①Use the special charger configured by the company to charge. It can be connected through the charging socket of the instrument or charged offline, but do not connect the positive and negative poles in reverse. ②Before charging the battery, there is no need to discharge the battery. ③ When the indicator light of the charger is off, it means that the charging is completed, it usually takes about 6 ~ 10 hours, please unplug the power plug after charging, do not charge for a long time. ④ When charging with the machine, please do not start the work, that is, do not start the instrument while charging. In this case, it is possible to cause voltage disturbances which may cause unstable power supply to the instrument and affect normal operation. ⑤ The charging time should not be too long, and should not exceed 24 hours. ⑥ The battery can be charged and discharged about 500 times. After that, the battery performance will be greatly weakened, resulting in a decrease in the working time of the battery. 3. Battery safety: Lithium batteries are dangerous goods. Serious violation of operation and storage requirements may cause explosion and fire. Therefore, special emphasis is placed on proper use and maintenance. The important notices are reminded as follows: ①Strictly choose the charger specially designed by our company. The charging voltage is strictly prohibited. ② Avoid overheating. Strictly grasp the use of the ambient temperature below 50 ℃, ③ absolutely avoid battery short circuit. Do not pile up messy with metal objects and do not immerse in water. ④ Avoid crushing, impact and strong vibration. ⑤ Please don't throw away the used batteries at will, and put them into the batteries for income.
