How big is a 2002 Lexus IS 300 battery?

There are often a few different size batteries that will work for the same car, and this is true of the 2002 Lexus IS 300. The sole engine available was a 3.0-liter, inline six-cylinder. The battery that’s needed is typically a BCI (Battery Council International) Group Size 24 or 34.

To know for sure what kind of battery your Lexus needs, you can check in your owner’s manual under the battery or specifications section. Or you can take the direct route—pop the hood and take a look at what’s currently in there.

It’s not uncommon for there to be a few different sizes of battery for any one model. Most battery or auto parts stores have guides that you can use to look up the battery you need based on the year, make/model, or VIN of your car. Here are a few different batteries that are recommended for the 2002 Lexus IS 300:

Super Start Platinum Battery Group Size 34, 750 CCA

Super Start Extreme Battery Group Size 24, 725 CCA

Duralast Gold Battery Group Size 24, 700 CCA

Duralast Battery Group Size 24, 600 CCA

CCA stands for cold cranking amps—the measurement of the number of amps that the battery can deliver at zero degrees Fahrenheit for 30 seconds. Batteries in the same Group Size can have different cold cranking amps, and the more CCAs a battery has, the more starting power it provides. Generally, batteries with a higher CCA are on the more expensive side.

2002 Lexus IS 300 battery life

In a gasoline or diesel-fueled vehicle, the battery will actually get recharged from the power generated by the engine as you drive. Handy, right?

But just like everything else on your car, the battery will eventually wear out and need to be replaced. On average, a car will need a fresh battery every four to five years, but this will vary depending on how often you drive and the climate where you live. Drivers in areas with extreme temperatures will go through car batteries faster than ones in more temperate areas.

In a perfect world, you should test your battery regularly so that you won’t get caught off guard by one that’s totally out of juice. In addition, watch for these other signs that your battery is nearing the end of its lifespan:

Clicking sounds when starting your Lexus

Visible corrosion on the battery

A frequent dead battery that often requires

jumping and/or charging

Lights that are dimmer than usual

How to keep your 2002 Lexus IS 300 battery healthy

Regular testing is the ideal way to keep tabs on your battery’s life, and here are a few things that will help to keep your battery healthy and happy as long as possible.

Start your engine and drive your car on a regular basis. Since your battery is recharged by your engine, you need to run your car on a regular basis to keep it charged. If you don’t drive a lot, start your engine and drive around for about 10 minutes every week. If you’ll be away from home for a while, try asking a friend take it out periodically.

Manually recharge the battery after storing your vehicle. If your car does sit for a long period of time, consider removing and manually charging your battery before starting it up.

Don’t leave your lights on. Leaving your interior or headlights on is a big drain on your battery, so remember to turn them off when they’re not needed.

Disconnect electronics when not in use. Unplug the cords to things like phones or other electronics when the car isn’t running.

Don’t neglect vehicle maintenance. Your car battery is one part of an intertwined whole, and problems with other areas of your car can also result in battery issues.
