A car's battery provides an essential supply of power; in fact, it would be impossible to operate your vehicle without one. When purchasing a battery for your Toyota RAV4, speak with a customer service agent at the automotive parts counter about reliable brand names and about installation. Though installing a car battery is simple, you should consult a professional your first time to ensure that you've placed it correctly.

A battery serves as the primary source of electrical power in an automobile. When the engine is turned off, the battery serves to operate the lighting and other systems, like the car alarm. As the engine starts, the battery provides power to the starter and for the ignition system. Once the engine is running, the battery provides power only when the supply from the charging system is not adequate for the needs of the vehicle.

Further, the battery provides protection to the engine by serving as a voltage stabiliser. In this capacity, the battery absorbs abnormal voltage in the electrical system, preventing the car's components from being damaged from transient, high voltages.


Regardless of the battery's brand, its physical specifications should be identical, or very close to the same. The battery for the RAV4, a small sport utility vehicle, weighs 10.5kg. and is 7.68 inches wide, 5.16 inches deep and 7.13 inches high.

These batteries are rated for a nominal voltage of 12. They have a rate capacity of 35 amp-hours (Ah), meaning that they can provide 1.75 volts per cell for at least 20 hours at 26.7 degrees Celsius; this is the lowest Ah rating for standard automobile batteries.

For a fully discharged RAV4 battery, it should take fewer than 75 minutes to charge to the battery's reserve capacity rating. To be able to provide at least 5 amps, the battery should charge for up to 10 hours.

Charging your Battery

Automotive batteries charge without assistance from the vehicle operator, but there are certain conditions that affect your battery's charging capabilities, the most common of which is the outside temperature. When the weather is cold, batteries take longer to charge, and you should never attempt to charge a frozen battery.

Though Toyota generally manufactures a reliable automobile, batteries frequently and occasionally inexplicably die. The most common reasons for battery failure are overcharging or undercharging, corrosion, extremely high or low temperatures, and vibration due to an improperly placed battery.
