I believe we all know that the car emergency start power battery is slowly becoming an important car companion in the self-driving tour family, its main function of the lithium battery with large electric equipment is to provide power to the engine ignition system and other electrical equipment when the car has no electricity and power loss. In fact, you do not say that the car emergency start power battery is not important to you, everything is not afraid of ten thousand, just afraid of one. If your car turns off in the middle of the night in that mountain den, it is estimated that it is also very scary. Moreover, the car emergency start power battery can not only give the car emergency ignition, he can also use the emergency power lithium battery to charge your mobile phone, tablet computer, even laptop computer, so that for people who often drive out more protection and choice, why not?

At present, the popular automotive emergency start power battery in the market can be mainly divided into lead-acid storage batteries and lithium polymer batteries, of course, lithium polymer automotive emergency start power batteries are gradually occupying the market initiative, because lithium polymer lithium batteries have high rate discharge capacity, small size, light weight, long service life and other advantages. However, at present, there are many people who use lead-acid storage automobile emergency start power supply batteries, so the following is mainly to introduce the use of lead-acid storage batteries for automotive multi-function emergency power supply:

1, when the lead-acid battery is discharged, it must avoid deep discharge or discharge with too large or too small current.

2, the discharge voltage of the lead-acid battery shall not be lower than the termination voltage of the lead-acid battery, and in the series, parallel connection and loading and unloading, the lead-acid battery should be prevented from short circuit.

3, in the case of normal use of multi-functional emergency power supply, the lead-acid battery should open its safety valve as far as possible, which can ensure the safety and reliability of the lead-acid battery.

4, the car multi-functional emergency power supply lead-acid battery should be recharged after the discharge, otherwise the shelf time is too long, will lead to the car multi-functional emergency power supply can not recover the capacity.

5, before the first use of sealed lead-acid batteries, although we do not need to charge it initially, but need to supplement it. When replenishing the charge, the current limiting constant voltage charging method should be used first, and then the charge should be carried out in accordance with the instructions.

6, because the car multi-functional emergency power supply using maintenance-free battery is made of lead calcium alloy, the decomposition of water is small, low evaporation, so it in the terminal, wire, the corrosion of the body is relatively small, strong resistance to overcharging, starting current, power storage time is long.

In addition, if the capacity of the automobile multi-function emergency power lead-acid storage battery is lower than 80% of the rated lead-acid battery, we should update it, so as to extend the service life of the automobile multi-function emergency power lead-acid storage battery, it also has a certain help.
