How Does Cold Weather Affect Deep Cycle Batteries

How Does Cold Weather Affect Deep Cycle Batteries? When the weather starts to get colder, we often get asked the question, how does the cold affect my batteries?

The answer will depend on the battery technology as each technology has its own characteristics. However, like human beings, all VRLA batteries perform best when stored and operated at room temperature (around 20°C).

The chemical reactions that take place within a VRLA Deep Cycle Battery are slower in lower temperatures, therefore slowing the performance and effectively lowering the capacity accordingly.

The colder the temperature is, the greater the effect. In extreme cases, the electrolyte in the Sealed VRLA (Valve Regulated Lead Acid) Deep Cycle Batteries can freeze rupturing the battery case. So it is always best to ask for advice on your system.
