Free QuoteOperating within the optimal temperature range affects several aspects of lead-acid batteries. The chemical reactions for charging and discharging occur more efficiently at moderate temperatures. Extreme heat can lead to electrolyte evaporation and reduced capacity, while extreme cold can slow down the chemical reactions, leading to poor performance.

Free QuoteIdeal operating temperature for Flooded deep cycle lead-acid batteries is 25°C (77°F). Battery capacity and cycle life is affected by operating temperature. Operating at higher temperatures will reduce cycle life due to cell degradation. A cycle life reduction of ~50% for every 10°C over 25°C (77°F) is expected.
SOME FACTS ON THE SUBJECT OF AMBIENT OR OPERATING TEMPERATURE. As a general rule, Banner recommends an operating temperature of max. -40 to +55 degrees Celsius; optimum storage conditions are approx. +25 to +27 degrees Celsius. These criteria apply to all lead-acid batteries and are valid for conventional, EFB, AGM and GEL technology.
If the float voltage is set to 2.30V/cell at 25°C (77°F), the voltage should read 2.27V/cell at 35°C (95°F). Going colder, the voltage should be 2.33V/cell at 15°C (59°F). These 10°C adjustments represent 30mV change. Table 3 indicates the optimal peak voltage at various temperatures when charging lead acid batteries.
A lead acid battery charges at a constant current to a set voltage that is typically 2.40V/cell at ambient temperature. This voltage is governed by temperature and is set higher when cold and lower when warm. Figure 2 illustrates the recommended settings for most lead acid batteries.
It is a matter of concern when electrolyte temperature increases above 25-27 ⁰ C to 35⁰ C and above. The charging voltage should be set at a lower value i.e reduce charging voltage by 3 mV for every increase of 1⁰ C rise above 27 ⁰ C. Otherwise, the life of the battery will be reduced due to higher gassing and grid corrosion.
Heat is the worst enemy of batteries, including lead acid. Adding temperature compensation on a lead acid charger to adjust for temperature variations is said to prolong battery life by up to 15 percent. The recommended compensation is a 3mV drop per cell for every degree Celsius rise in temperature.
