Why are lead-acid batteries undercharged?
This result is potentially symptomatic of increased internal resistance and power fade: the batteries have capacity that can be charged, but over time the full capacity may only be available at low charge powers. The lead-acid cells show much greater undercharge under all protocols than the other chemistries.
What causes a lead acid battery to fail?
Besides age-related losses, sulfation and grid corrosion are the main killers of lead acid batteries. Sulfation is a thin layer that forms on the negative cell plate if the battery is allowed to dwell in a low state-of-charge. If caught in time, an equalizing charge can reverse the condition.
How efficient is a lead acid battery?
Its efficiency is a measure of energy loss in the entire discharge/recharge cycle. eg. For an 80% efficient battery, for every 100kWh put into the battery, only 80kWh can be taken out. With new lead acid batteries efficiencies of ~ 80 - 90% can be expected, however this decreases with use, age, sulphation and stratification.
Why does a lead acid battery last so long?
The primary reason for the relatively short cycle life of a lead acid battery is depletion of the active material. According to the 2010 BCI Failure Modes Study, plate/grid-related breakdown has increased from 30 percent 5 years ago to 39 percent today.
