Effect of Battery Temperature on Battery Life
Lead acid batteries are electrochemical storage devices that store and release chemical energy upon
demand in the form of electricity. By virtue of their design lead acid batteries are highly reactive to
temperature – with the rate of chemical reactions that occur within the battery being affected by the
operating temperature where the battery is used. Higher operating temperatures will result in faster
chemical reactions within the battery – delivering improved discharge performance; conversely, cooler
operating temperatures will result in slower internal chemistry. However, higher operating temperatures
also result in shortened battery life as the increased rate of chemical reactions will accelerate the rate of
deterioration of internal components.
Typical battery life is based upon a baseline operating temperature of 80°F / 27°C. Temperature
increases of 15°F / 10°C over the baseline will cause the battery’s rate of internal chemical reactions
to double – something that will reduce battery life due to the accelerated deterioration of internal
components. Please contact Crown Battery to discuss any minimal requirements for battery life when
operating batteries in temperatures greater than 80°F / 27°C.

APPLICATION RECOMMENDATIONS
Specific Gravity Operating Temperature Range Self Discharge Terminal Torque Specifications
Fully charged battery specific gravity
(100% state-of-charge) is 1.275
Fully discharged battery specific gravity
(100% depth-of-discharge) is 1.125
-40°F to 120°F (-40°C to 49°C). Flooded
lead acid battery capacities are temperature
sensitive: refer to the temperature / capacity
projection chart below to identify available
capacity at the application operating
temperature. Application Note: Maintain
a state of charge greater than 60 percent
when operating flooded lead acid batteries
at temperatures below 32°F (0°C).
Fully charged batteries that are stored
at a temperature of 80°F (27°C) will
self-discharge at a rate of 3.5% per week.
SAE / Automotive Terminal Style:
50 to 70 in-lbs / 6 to 8 Nm
Stainless Threaded Terminal
(Types C, S, Z):
100 to 120 in-lbs / 11 to 14 Nm
Application Note: Lead acid batteries contain corrosive battery electrolyte and generate highly flammable hydrogen gas. When working near batteries wear protective clothing, gloves, and safety glasses when handling batteries and electrolyte and always
work in a well-ventilated area. Do not over-torque terminals. Over-torque can result in terminal damage, breakage, terminal meltdown or fire.
Crown Battery’s flooded lead acid deep cycle batteries require periodic preventative maintenance and effective charging service to ensure dependable service life. Customers can find Crown Battery’s recommended best practices for deep cycle battery care,
