Recently, lithium batteries for cars have become more and more popular. They are lightweight compared to their lead counterparts. Many of these batteries have been developed and are designed for a variety of equipment (electric vehicles, motorcycles, etc.). However, is it worth installing a lithium battery in ordinary vehicles with gasoline or diesel internal combustion engines? Indeed, even today, manufacturers have not been able to completely eliminate the flaws of lithium batteries such as safety, allowable operating temperature range and recharge time.

Is it profitable (for the price) to buy a lithium battery
According to some technical characteristics, lead-acid batteries are significantly inferior to their lithium counterparts. First of all, it should be noted that the mass of lead-acid batteries is 80% greater. In addition, compared to Lion batteries, they have a shorter lifespan. However, the price of Lion batteries is several times higher than that of lead-acid models. Therefore, in this case, the statement that it is more profitable to install batteries in a Lion car, instead of standard acid batteries, is doubtful.
Operating temperature range
It should be noted that Lion batteries have an increased level of sensitivity to high temperatures or vice versa. The optimum environmental operating range for these products is 10 to 35 degrees Celsius. When exposed to low temperatures, Lion battery performance begins to drop sharply.
However, it should be noted that manufacturers have developed special models of Lion batteries designed to operate at low temperatures. They are able to maintain a stable charge even if the ambient temperature drops to -40 degrees Celsius. However, such batteries are able to operate exclusively with a limited discharge rate.
When overheated or heavily overcharged, lithium batteries can begin to break down. In this case, when such a battery is destroyed, a leak of poisonous gas begins. In addition, the destruction of the Lion battery can be the main cause of a fire or an explosion.
If a short circuit occurs in the electrical circuit of the car, the Lion battery will begin to overheat. It may also cause fire and explosion of the device. It should be noted that lithium models, in comparison with their lead counterparts, are equipped with a special liquid electrolyte, which ignites very easily and quickly.
Does not support constant load
Lithium batteries have many advantages, but at the moment their use in vehicles with diesel and gasoline engines is inefficient. Also, the alternator that produces alternating current in a car is not capable of recharging such batteries. It is for this reason that Lion batteries are practically not installed on diesel and gasoline vehicles.
In addition, they cannot be constantly charged (give a full charge) over a long period of operation. In addition, such devices are contraindicated for constant and complete discharges (to zero). Otherwise, with constant charging, the capacity of Lion batteries begins to drop.
Need a balancer
When charging lithium batteries, in which the cells are connected to each other in series, it is imperative to use a special controller, as well as to apply charge balancing for each individual cell. Otherwise, the battery resource will begin to drop sharply, and the charge level will not exceed 2/3 of the standard nominal value. Therefore, when recharging such devices, special balancers are also used, which are able to pump energy between the battery cells and equalize the voltage.
