Why Does a Block Heater Drain the Battery in the First Place?
Your block heater can drain your car battery due to its electrical consumption while operating. A block heater is designed to warm the engine coolant, making it easier for the engine to start in cold temperatures. However, the heater requires electrical power to function, which can lead to battery drain if used for extended periods.
The definition of a block heater is reflected in guidance from the Canadian Automobile Association (CAA), which states that a block heater aids in pre-warming the engine and improving cold-weather starts.
The underlying causes of battery drain from a block heater include the electrical load it imposes on the battery. When plugged in, the heater typically consumes between 400 to 1,500 watts of power depending on the model. This consumption can reduce the battery’s charge if the vehicle is not started to replenish that energy.
Key technical terms to note are:
– Electrical Load: The amount of power drawn by an electrical device.
– Battery Charge: The stored electrical energy in a battery available for use.
The mechanisms involved in battery drain are straightforward. When a block heater operates, it draws current from the battery. If the battery is not regularly recharged by the engine running after the heater is unplugged, its energy levels will diminish, leading to a partially drained or completely dead battery. Additionally, if the battery is already old or weak, its ability to sustain charge diminishes, making it more susceptible to drain from auxiliary devices like a block heater.
Specific conditions that contribute to this issue include:
– Extended use of the block heater without starting the engine.
– Cold ambient temperatures that require longer heating periods.
– A weak or old battery that can’t hold a charge effectively.
