Temperature Compensation


What is Temperature Compensation?

The chemical reactions that occur within batteries vary with temperature. These variations cause a battery charged or maintained at standard voltages to be undercharged if cold, and overcharged if hot. BatteryMINDers with temperature compensation precisely adjust battery voltage based on temperature sensor readings. This ensures your battery will always be properly charged and maintained no matter what conditions it is subject to. Follow the simple suggestions on our temperature compensated models for prolonging the life of your battery and you will have it for many years to come. 

Effects of Extreme Heat

According to Battery University, heat is the worst enemy of most batteries, including lead acid, but it can't always be avoided. As a guideline, each 8°C (15°F) rise in temperature cuts the life of a sealed lead acid battery in half. Chargers exposed to temperature fluctuations should include temperature compensation sensors to adjust the charge voltage for optimum charge efficiency. Temperature compensation on a lead acid charger adjusts for temperature variations and prolongs battery life. 

Effects of Extreme Cold

Additionally, do not freeze a lead acid battery. This could cause permanent damage. Always keep the batteries fully charged. Flooded lead acid batteries tend to crack the case and cause leakage if frozen; sealed lead acid packs lose potency and only deliver a few cycles before a replacement is necessary.

Important Temperatures to Remember

Operating Temperature: -20°C (-4°F) to 40°C (104°F) 
Storage Temperature: -40°C (-40°F) to 85°C (185°F) 
Temperature Compensation: -20°C (-4°F) to 40°C (104°F)
