Overcharging with high charging voltages generates oxygen and hydrogen gas by electrolysis of water, which bubbles out and is lost. The design of some types of lead–acid battery (eg "flooded", but not VRLA (AGM or gel)) allows the electrolyte level to be inspected and topped up with pure water to replace any that has been lost this way.
When the battery provides current, there is a voltage drop across R S, and the terminal voltage v < v s. To charge the battery, a voltage v > v s. must be applied to the battery terminals. A real battery consists of a

Therefore, the conditions of use and storage will directly affect the performance of the battery. As of today, common rechargeable batteries are lead–acid battery series and lithium-ion battery series.
High temperatures reduce voltage and performance in lead-acid batteries. They have a negative temperature coefficient, which means their terminal voltage drops as temperature increases, assuming the charging current stays constant. This effect can shorten battery life and efficiency.
It''s a typical 12 volt lead-acid battery discharge characteristic and it shows the initial drop from about 13 volts to around 12 volts occuring in the first minute of a load being applied. Thereafter, the discharge rate doesn''t unduly affect the output voltage level until the battery gets quite depleted of stored energy.
