Still, the Inverter/UPS will keep charging it till 14.4 Volts, which will overcharge the storm, and the electricity to charge will also go to waste

The effect of low temperatures on lead batteries

What are temperature effects on batteries?

Battery capacity is reduced by 50% at -22 degrees F – but battery LIFE increases by about 60%. Battery life is reduced at higher temperatures – for every 15 degrees F over 77, battery life is cut in half. This holds true for ANY type of lead-acid battery, whether sealed, Gel, AGM, industrial or whatever. This is actually not as bad as it

BU-410: Charging at High and Low Temperatures

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.

Comprehensive Guide to Temperature Effects on Batteries

At extremely low temperatures, such as -40°C (-40°F), the charging voltage per cell can rise to approximately 2.74 volts, equating to 16.4 volts for a typical lead-acid battery. Conversely, at higher temperatures around 50°C (122°F), the charging voltage drops to about 2.3 volts per cell, or 13.8 volts in total. This variation necessitates
