Generally speaking the use of battery cycle in 2-3 years or so, but if used properly owners Life expectancy is 4-5 years can be achieved. Some errors in use and may lead to injury, these will greatly shorten the battery life is also the owner of the questions required attention:

1, the electrolyte density is not normal sulfuric add.

2, non-maintenance-free dell laptop battery  vent plug: Non-maintenance-free battery vents are used to heat and release of internal pressure, if the ventilation holes blocked, will lead to increased internal pressure, would lead to serious battery explosion happened.

3, the charge is not correct: dell 1691p  charging time should be used for small current method, if the use of high-current charge time can cause electrolyte boiling heat, internal water evaporation, so that the density of electrolyte change.

4, a long time working under a state of electricity loss.

5, no electricity storage: If the owner because of negligence caused by excessive discharge of batteries, after you restart the vehicle, shall be guaranteed at least one engine operating hours for the battery charging. Conditional circumstances should drive, even in conditions of idling can also recharge the inspiron 700m battery . Want to improve charging effects such as increased engine speed, and generally can be made good 1200r/min charging effect.

Occasionally, one or two batteries had discharge situation appears to have little effect battery life, as long as the owners in resolving the problem, to ensure adequate battery can, long-term electricity deficit state in the work of the greatest damage the battery life. Charging improper job losses electric inspiron 710m battery life for the greatest impact, if there have been battery discharge, the fault must be resolved to ensure that battery charge time.
