HUP Batteries Q & A

Because batteries are a chemical reaction, and chemical reactions change with temperature, temperature influences the efficiency and life-span of your batteries. For a bench mark, all lead-acid batteries use 77°F - 80°F to determine capacity. It also comes into play when using a hydrometer. Lower temperatures cause lower interaction of the chemicals and thereby reduce capacity. Higher temperatures have the opposite effect. Lower or higher temperatures must also be taken into account when charging your battery. Most of today's charge controllers and inverter / chargers have temperature compensating abilities.
