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.
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.
It should set the voltage higher when the battery is charged at lower temperatures and a lower voltage when charging at higher temperatures. The charge should be at 0.3C or less when the temperature is below freezing. Nickel-based batteries: A nickel-based battery can have a current charge reduced to 0.1C if temperatures are below freezing.
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.
Lead-acid: Lead acid is reasonably forgiving when it comes to temperature extremes, as the starter batteries in our cars reveal. Part of this tolerance is credited to their sluggish behavior. The recommended charge rate at low temperature is 0.3C, which is almost identical to normal conditions.
Lead-acid batteries contain lead grids, or plates, surrounded by an electrolyte of sulfuric acid. A 12-volt lead-acid battery consists of six cells in series within a single case. Lead-acid batteries that power a vehicle starter live under the hood and need to be capable of starting the vehicle from temperatures as low as -40°.

This blog covers lead acid battery charging at low temperatures. A later blog will deal with lithium batteries. Charging lead acid batteries in cold (and indeed hot) weather needs special consideration, primarily due to the fact a higher charge voltage is required at low temperatures and a lower voltage at high temperatures. Charging therefore needs […]
Low temperatures reduce the output of a lead-acid battery, but real damage is done with increasing temperature. For example, a lead-acid battery that is expected to last for 10 years at 77°F, will only last 5 years if it is operated at 92°F, and just a year and a half if kept in a desert climate at a temperature of 106°F. Starter batteries ...
The answer to your question being -4º F is the minimum recommend storage temperature to store a Sealed Lead Acid (SLA) battery. Also of note – Sealed Lead Acid (SLA) batteries can also be stored in extreme conditions down to -40º F and up to +140º F, but won''t except a charge/ cycle as designed in these conditions. In extreme conditions ...
The operating temperature of lead-acid batteries typically ranges from -20°C to 50°C (-4°F to 122°F). However, it''s important to note that extreme temperatures, both hot and cold, can have an impact on the performance and lifespan of lead-acid batteries.
A fully charged cell is less susceptible to freezing, but even a fully charged cell may fail when its temperature falls to about -21°C. Lead Acid Battery Example 1. A lead-acid battery has a rating of 300 Ah. Determine how long the battery …
