Although hybrid batteries were intended to last the lifetime of the vehicle, some battery packs are losing power and performance earlier than their owners would like. Tell-tale signs include low energy, reduced torque, quick loss of battery charge, limited performance and significantly lower gas mileage.
A common cause of battery failure is acid stratification. The electrolyte on a stratified battery concentrates on the bottom, causing the upper half of the cell to be acid poor. This effect is similar to a cup of coffee in which the sugar collects on the bottom when the waitress forgets to bring the stirring spoon.
