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. 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
For flooded lead-acid batteries, testing specific gravity on a regular basis is the best method to confirm proper charging, battery health and current state-of-charge.

Sealed lead acid cells are used in many projects in Sandia National Laboratories Department 2660 Telemetry and Instrumentation systems. The importance of these cells in battery packs for powering electronics to remotely conduct tests is significant.

Manufacturers of lead acid batteries usually publish temperature compensation factors that apply to the operating float voltage in standby service, which is intended for use within the range of recommended operating temperature. They are applied to adjust the float voltage and maintain the battery in a full state of charge. For flooded (i.e., vented) lead acid batteries, however,

Temperature Compensation. In North America, it is usual that battery performance and charging voltage is referenced to a nominal 77ºF (25ºC). Significant excursions above or below this norm will affect the way the battery should be charged, and this is significant for VRLA cells. Besides shortening battery life by causing electrolyte depletion (dry out) and positive grid/plate

temperature for the lead-acid battery is 25 °C (77 °F) [26]. It is important to note that increasing the temperature by 10 °C (18 °F) will result in roughly a 50% reduction in battery service life. On the other hand, reducing the temperature by the same amount can reduce the capacity of the battery by roughly 25% [30,31]. 4.1 Battery temperature compensation Temperature
let''s use a 24V system, with a charge voltage of 28.6V, a temperature compensation value of -5mV/°C/cell, and a battery temperature of 40°C. From the system voltage, there are 12 battery cells (24V / 2V per cell). -0.005V/°C/cell x 12 cells = -0.06V/°C. 40°C-25°C = 15°C x -0.06V/°C = -0.9V + 28.6V = 27.7V.

What is Battery Temperature Compensation and Why is it Needed. The chemistry in lead-acid batteries causes energy to flow more easily in warm temperatures and less easily in cold temperatures. This affects how much energy a battery can absorb during the recharge process. Most charger voltage setpoints are set for room temperature, 25°C [77°F

A proper charge regime with the appropriate temperature compensation scheme is critical to prolonging the service life of the VRLA battery. The charge regime should minimize the degree of overcharging to reduce the rate of positive grid corrosion and water loss.
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.
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.
If your batteries are exposed to warm or cold weather, it’s important that your battery charger has temperature compensation in order to maximize the life of the batteries by assuring that they’re receiving the proper recharge setpoints in all weather conditions.
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.
Temperature compensation for float charging involves the adjustment of the float voltage to prevent thermal runaway when the temperature is high and to prevent cell gradual self-discharge when the temperature is low as shown in Fig. 8.
Charging therefore needs to be ‘temperature compensated’ to improve battery care and this is required when the temperature of the battery is expected to be less than 10°C / 50°F or more than 30°C / 85°F. The centre point for temperature compensation is 25°C / 77°F. Cold weather also reduces a battery’s capacity.
