1、Depth of discharge
Discharge depth that is the use of the process of discharge to what extent to start to stop. 100% depth refers to the discharge of all capacity. The life of lead-acid storage is greatly affected by the depth of discharge. The focus of design considerations is the deep cycle use, shallow cycle use or floating charge use. If the shallow-cycle battery is used for deep-cycle use, the lead-acid battery will fail quickly.
Because the positive active material lead dioxide itself is not firmly bonded to each other, it generates lead sulfate when discharging and reverts to lead dioxide when charging, the molar volume of lead sulfate is larger than that of lead oxide, so the volume of active material expands when discharging. If one mole of lead oxide is converted into one mole of lead sulfate, the volume increases by 95%. This repeated contraction and expansion makes the mutual bonding between lead dioxide particles gradually loosen and easy to fall off. If one mole of active material of lead dioxide is only 20% discharged, the degree of shrinkage and expansion is greatly reduced, and the bond destruction becomes slow, therefore, the deeper the discharge depth, the shorter the cycle life.
2、Overcharge degree
There is a large amount of gas precipitation when overcharging, when the positive plate active material suffers from the impact of gas, this impact will promote the active material off; in addition, the positive plate grid alloy also suffers from serious anodic oxidation and corrosion, so the battery overcharge will shorten the application period.
3、The influence of temperature
Lead-acid battery life with the temperature increases and lengthens. In 10 ℃ to 35 ℃, each 1 ℃, about 5 to 6 cycles, between 35 ℃ to 45 ℃, each 1 ℃ can extend the life of more than 25 cycles; higher than 50 ℃ is due to the loss of negative electrode sulfide capacity and reduce the life.
Battery life increases with temperature in a certain temperature range because the capacity increases with temperature. If the discharge capacity remains unchanged, its depth of discharge decreases when the temperature increases, and the solid life is extended.

4、The effect of sulfuric acid concentration
The increase of acid density, although the positive plate capacity is beneficial, but the self-discharge of the battery increases, the corrosion of the plate grid is also accelerated, also prompting the loose lead dioxide off, with the increase of acid density used in the battery, the cycle life decreases.
5、The effect of discharge current density
As the discharge current density increases, the life of the battery decreases, because under the condition of high current density and high acid concentration, the positive lead dioxide is prompted to loosen and fall off.
