Lithium iron phosphate batteries can be tipped. Taking “lithium batteries for electric vehicles” as an example, they can be tipped to the side for a short period of time, but not often. Most electric vehicle batteries can be placed upside down, but those containing acid cannot be used. They should not be charged backwards, otherwise sulfuric acid will leak and the battery will be damaged. To determine if the battery can be added with acid, check if the battery cover can be opened. Whether it is a lithium battery or a nickel-metal hydride battery, there is no problem whether to put it upside down or not. If it is a lead acid battery, it generally cannot be reverse charged.
Lead acid batteries currently used in electric vehicles are all electro batteriessealed colloidal lyte, which can be placed sideways or upside down. In the car battery box, if you take it apart and look at it, you can see whether it is placed vertically or horizontally. This type of battery does not need to be added with water, and water cannot be added.
Note: Electric vehicle batteries are generally maintenance-free lead-acid batteries. The difference from ordinary lead-acid batteries is that there is a sponge-like layer between the plates and the electrolyte is absorbed there. In theory, regarding how to place it, the electrolyte is sandwiched between the plates and the charging and discharging effects are the same. However, if the battery is of poor quality, the electrolyte will still leak. Lead acid batteries generally cannot be reverse charged. Lithium batteries and nickel-metal hydride batteriesThey have no problem being placed upside down or not.
Three major taboos of lithium batteries: temperature Lithium batteries are afraid of high temperatures. Large current, for example, 18650 battery cells are discharged at 3C and electric vehicles are 8000W. The battery cells used are lower than the discharge current of electric vehicles. This will cause the lithium battery to be too high in temperature, current. be too large, and the service life will be shortened, and it will also cause the case to bulge and be scrapped. Electric vehicles are very powerful and very fast. It is recommended to choose 18650 batteries with a current of 10C. It is obviously very important to choose the right battery.
Store at full charge. The ternary lithium battery is fully charged at 4.35V. The protection board on the market stops charging at 4.2V. Generally,When electric vehicle lithium batteries are stored for a long time, 50.% of full charge is best. Long storage time will reduce the capacity of the lithium battery. Except for lithium iron phosphate and lithium titanate, be sure to choose a better quality protective board.

Specific method: 1. Insert the weak battery after the power runs out. . Freeze the battery in a home refrigerator for two days, take it out, bring it to room temperature and recharge it using the new battery method, usually more than 8 hours butno more than 12 hours. Then install it on your mobile phone and use it, and surprises will appear. The power is restored to its original state, but you still need to be careful not to freeze the battery packaging.
2. Charge the battery at low voltage, set the regulated power supply to around 3V, and continue charging the battery. Charging takes between ten minutes and half an hour.
