What Information Do You Need to Replace a Car Battery?

• Start by looking up the correct BCI group battery size for your Lexus ES 300, which can be found in your owner's manual.
• Find the recommended CCA (Cold Cranking Amps) rating for your vehicle, which is also listed in your owner's manual.
• You can buy a battery with a higher than recommended CCA rating, but do not buy one with a lower number of CCAs than your vehicle requires.
• Check your owner's manual or the label on your current battery to determine if your battery requires an AGM battery.
• If your vehicle requires an AGM battery, you must replace it with another AGM option.

What are the Differences Between Flooded and AGM Batteries?

• Flooded batteries are the most basic replacement battery options and also cost the least upfront.
• AGM batteries cost more, but provide more power than flooded batteries. This allows you to start your engine more easily in extremely hot and cold climates.
• Even though AGM batteries cost more upfront, they are designed to last 2-3X longer than a flooded battery, which can save you money in the long run.
