Battery Heaters

FAA-PMA Approved

This item discontinued due to low demand

A nice toasty preheated engine won't do you much good if the battery won't crank it. At cold temperatures a lead acid battery's power is reduced by 60% or more. A battery heater can boost battery power back to 100% and improve engine starting reliability even in the coldest weather.

When a battery heater is installed it always goes with you wherever you fly - just like our engine heaters.

• Acid resistant flexible pad heater installs inside the battery box beside or under the battery.
• Thermostat controlled to prevent overheating the battery, and to maintain it at the optimum temperature (turns on below 72^oF, turns off above 80^oF).
• 120 or 220 V available.
• 40 watts, 7" x 5"

Note that the thermostat on our heater is located inside the battery box so it controls the temperature of the battery. The thermostat on our competitor's battery heater (which is priced over 4 times higher than ours) is attached to the aircraft skin, and turns the heater on when the temperature of the skin, i.e. ambient temperature, is 32^oF or below. They have no thermostat inside the battery box to insure that the battery does not overheat, which causes the acid to evaporate away. When the ambient temperature is below 32^o their heater runs continuously regardless of the temperature of the battery.

A battery heater is especially helpful when the battery is remote mounted in the rear of the fuselage, as in Cherokees and Mooneys, or in the nose or wing bay as in twins. Batteries mounted in the engine compartment will be heated by the engine heater if the cowling is covered, so a battery heater may not be necessary unless you want to preheat quickly.
