How to determine battery group size on Toyota RAV4?

  • Take a close look at your current battery. If it’s an original one, the group size should be printed on the label. Other useful information, such as reserve charge and CCA, can also be found there.
  • The simplest way is to consult a professional whose job it is to keep your auto in good working order.

Starting battery vs deep cycle: what’s the difference?

You’ve definitely heard the terms “Starting battery” and “Deep-cycle battery.” But what’s the difference between them? And which one is suitable for your car? You should learn the details before buying a battery replacement for your Toyota RAV4.

Starting or SLI battery – this type provides temporary power to the engine – it’s only used when you start your vehicle. Once the engine runs for 30 seconds, the alternator will take over and draw power from the car’s electrical system. As a result, a starting battery can perform for several years without any issues.

Deep-cycle battery – as the name implies, this type can be utilized to the very end of its charge. It can handle repeated charge and discharge cycles without degrading too quickly. A deep-cycle battery is a perfect choice for those who have electric boats, golf carts, or solar applications.

Toyota RAV4 battery buying guide

Does CCA (cold cranking amps) really matter?

It all depends! Of course, cold cranking amps (CCA) are an essential factor when it comes to choosing a car battery for your RAV or any other vehicle with a similar size engine.

A higher CCA rating will provide enough ignition power to quickly start the car in colder climates and during those long winter nights when temperatures drop below freezing.

On the other hand, the higher the CCA rating, the more expensive a battery is. But not all automobiles require high-cranking-power equipment! For example, if your car isn’t frequently exposed to sub-zero conditions, there’s no need for a battery with additional CCAs.

What is an AGM design for batteries?

An AGM (absorbed glass mat) battery is engineered for producing stronger bursts of starting amps and helping electronics run longer. In addition, the AGM design holds electrolytes in a fiberglass-type material so that the battery can be mounted in many positions with no spills or leaks.

Such a battery is sealed and requires no water to be added, making it very convenient when it’s difficult or impossible to check the electrolyte level. Furthermore, an AGM battery offers reduced gas emissions during charging, a low self-discharge rate, and longer service life.

All these features give AGM batteries unbeatable advantages if compared to conventional wet-cell or flooded batteries. For instance, a standard battery must be kept upright at all times since it uses gravity to return electrolytes to the plates. Besides, you have to fill a conventional battery with distilled water, or it’ll lose its charge if left sitting for too long. Conversely, AGM batteries can remain idle without a loss of power or charging capability. Finally, it boasts durable construction and can sustain more shock than a standard battery.

FAQs

When does your Toyota RAV4 battery need to be replaced?

Toyota RAV4 battery

One of the most prevalent car problems is a dead battery. We’ve all done it: didn’t completely close the door, left the lights on, or left the radio on without the engine operating for too long. When should you replace the battery, though? Here are some indicators that your battery should be inspected and probably changed:

  • The vehicle is slow to crank, especially on cold days
  • Electronics work, but the auto doesn’t start
  • Dim headlights despite the battery being fully charged
  • Massive rust is visible on the battery wires and connectors
  • The battery level of fluid is low
  • The fluid leaks
  • You can hear a clicking sound when starting the car
  • You’re noticing a general decrease in performance.

How long should a Toyota RAV4 battery last?

Toyota RAV 4 batteries usually last between 3 and 5 years. However, factors like the battery type, climate and weather conditions, driving patterns, car model year, etc., significantly influence the shelf life of your power source.

If you’re wondering how to prolong the battery life, here’s what you should do:

  • Keep your vehicle away from excessive temperature changes
  • Vibrations can loosen connections and rattle your battery’s parts, so keep it well attached
  • When not in use, turn off the audio, lights, and other electrical equipment
  • When you stop for more than 30 seconds, turn the car off
  • Clean the terminals and posts of rust with a brush and right cleanser

Is it safe to drive with the battery light on?

Toyota check display

It’s not advisable to drive with the battery light on because it could signal a problem with your car. It happens when the auto tries to charge the battery but can’t because of a lack of power. The battery light could also come on if you have a loose or corroded connection, a large enough series of load disconnects, or an open circuit in the electrical wiring. These are all problems that require attention from a qualified technician. So, it would be better to pull over and call a tow truck.

However, many automobiles have a reserve mode that allows you to continue driving even if the battery warning light illuminates. Most cars will let you drive up to 1000 miles in this mode, but be sure to turn off the stereo, air conditioner, and other equipment to avoid draining the battery.

How to replace the battery on the Toyota RAV4?

Changing some types of batteries, especially in newer models, might be difficult due to the shrinking hood area to increase the car’s performance. As a result, some batteries can be tricky to get to. So, the first step you should take is to read the owner’s manual and learn where the battery is placed in your Toyota RAV4.

Here’s general information on how to replace the battery:

  1. Remove the old battery. Make sure not to touch any of the liquids inside it – they contain sulfuric acid, which can cause burns
  2. Remove brackets and hoses that are attached to the battery
  3. Clean off any corrosion on the terminals
  4. Locate the new battery where it’s supposed to be
  5. Attach the negative cable to its terminal
  6. Attach the positive cable to its terminal
  7. Tighten the connections by hand first followed by tightening them with an adjustable wrench
  8. Repeat the process for the other battery terminal

As you can see, it is not very difficult to replace your car’s battery as long as you have a little knowledge about how things work under the hood.
