Batteries use environment:
(1) to avoid direct contact between batteries and metal containers, acid-resistant and heat-retardant materials should be used, otherwise they may cause smoke or combustion。
(2) the chargers used are charged under conditions that otherwise may cause the battery to overheat, vent, leak, burn or break。
(3) do not install batteries in sealed equipment, otherwise it may break the equipment。
(4) when batteries are used in medical equipment, install backup power sources outside the main power source, otherwise failure of the main power source will cause injury。
(5) placing the battery away from the place where the spark equipment can be generated, otherwise the spark may cause the battery to smoke or break。
(6) batteries should not be placed near thermal sources (e. G. Transformers), otherwise they may cause overheating, leakage, combustion or rupture。
(7) when the number of batteries in application exceeds one, ensure that the battery is connected correctly and is connected correctly to the charger or load, otherwise the battery will break, burn, or damage the battery and, in some cases, cause injury。
(8) pay particular attention to not allowing batteries to be hit on feet。
(9) the extent of use of batteries is as follows. Battery damage may result from this range。
The normal operating range for batteries is: (25°c)
Battery discharge (filled in equipment): to (-15°c to 50°c)
After charge: to (0°c to 40°c)
In storage: to (-15°c to 40°c)
(10) do not place batteries mounted on board at high temperatures, in direct sunlight, in furnaces or in front of fire, otherwise they may cause leakage, fire or break。
(11) do not use batteries in dust-filled areas, which may cause battery short circuits. When batteries are used in a multi-dust environment, batteries should be checked periodically。

Pre-use attention to batteries:
(1) ensure adequate insulation between and around batteries and equipment. Inadequate insulation measures may cause electric shocks, short-circuit heat, smoke or combustion。
(2) a charge application charger, directly connected to a direct current power source, may cause a leak, heat or combustion of the battery。
(3) the battery capacity will be reduced slowly due to self-charge. Recharge batteries before storage is used for long periods。
Use of batteries in the environment
Lead-acid batteries are used in workplaces where natural ventilation is good and ambient temperatures are good at 25°10°c。
Lead-acid batteries will be used under these conditions very much: conductive batteries are well connected, not severely overloaded, heat sources are not directly radioactive and natural ventilation is maintained。
Battery installation:
Accumulation cells shall be removed from thermal sources and from areas prone to sparks at a distance greater than 0. 5 m。
2. Accumulation cells shall avoid direct sunlight and shall not be placed in environments of large amounts of radioactive, infrared, ultraviolet, organic solvent and corrosive gases。
3. The ground should be installed with sufficient carrying capacity。
4. Owing to the high voltage of the battery assembly and the risk of electroshock, insulation tools should be used in handling the conductor link, and insulation gloves, aprons and protective glasses should be worn for installation or handling of batteries. Batteries can only be carried with non-metallic straps and cannot be carried with wire ropes, etc。
5. A dirty link or a lack thereof can cause battery fire or even damage to the battery, so that it should be carefully checked and removed and the link tightened。
6. Battery batteries of different capacity and performances cannot be used interchangeably, and the total voltage and positive and negative of the battery system should be carefully checked prior to the installation of end-end connectors and guidance battery systems to ensure their correct installation。
7. Battery casings, which cannot be cleaned with organic solvents, and carbon dioxide extinguishers cannot be used to extinguish cell fires。
When the battery is connected to the charger or load, the circuit switch shall be located at the "disconnected" position and ensure that the connection is correct: the battery is active with the charger and negative with negative。

Batteries use and attention:
1. Battery charge-out plants, from exit to installation, are subject to varying degrees of loss of battery capacity and, in the event of a longer period, should be recharged prior to commissioning. If the battery is stored for a period of less than one year, it is charged at a constant pressure of 2. 27v/only for five days. If the cell is stored for a period of 1-2 years, it will be charged at a constant pressure of 2. 33 v/only for five days。
When a battery is used, it shall be guaranteed a floating voltage value of 2. 25-2. 30 v for each single cell, which, if above or below that range, will reduce the battery capacity or life。
3. When the holding cell is running, the battery's single-body battery voltage shall not be less than 2. 20 v or, if the single-body voltage is less than 2. 20 v, the charge shall be balanced. The method for balancing charge is 2. 35 v/only and 12 hours。
4. Recycle batteries with a constant pressure limit after discharge. The specific method for charging charged voltages of 2. 35 to 2. 45 v/only, large currents of not more than 0. 25 c10, is to charge constant currents first with currents of not greater than the above-mentioned large current values, to be charged to single-body average voltages of 2. 35 to 2. 45 v instead of an average single-body voltage of 2. 35 to 2. 45 v until the charge ends。
5. Complete marking of charge when the battery is recycled: the marking of sufficient charge under the above-mentioned limit constant pressure may be used as a basis for judgement in either of the following two articles:
(1) charge time of 18-24 hours (non-deep discharge time may be short)。
(2) the current value of charging at the end of the charge period remains unchanged for three consecutive hours。
(3) a constant pressure of 2. 35 to 2. 45 v is the specified value of 25°c at ambient temperature. When ambient temperatures are higher than 25°c, charge voltage is reduced accordingly, resulting in overcharge. When ambient temperatures are below 25 °c, charge voltage shall be used to charge insufficient. The usually lower or lower range is 0. 005 v per unit of 1°c。
Accumulation batteries shall be recharged immediately after discharge, and if they are put on hold for too long, even recharges will not restore their original capacity。
7. When batteries are used, the bolts of the wires shall be tightened to avoid sparks and exposure。
