What Do I Need to Know Before Replacing My Car Battery?

• Look up the correct battery group size   either online or in your owner's manual
• Look up the CCA rating   for your Mercedes Benz GLK350 in your owner's manual
• If you live in a particularly cold area, you can purchase a battery with a higher CCA rating than your vehicle recommends, but don't buy one with a lower CCA rating

Which is Better AGM or Flooded Battery?

• There are 2 types of auto batteries: flooded & AGM
• Flooded batteries cost less than AGM batteries, but have shorter lifespans and may require additional maintenance
• AGM batteries cost more upfront, but last longer, meaning you'll probably save money in the long run with an AGM battery
• AGM batteries provide more power than flooded batteries, allowing you to start your engine more easily in extreme hot and cold weather.
• AGM batteries are also designed to last 2-3X longer and recharge faster than a flooded battery

Can I Use a Flooded Battery Instead of AGM?

• If your vehicle originally had an AGM installed when it came from the manufacturer, you must replace it with another AGM battery
• If your vehicle originally had a flooded battery installed when it came from the manufacturer, you can replace it with another flooded battery, or upgrade to an AGM option

Why Does My Mercedes Have 2 Batteries?

• The Mercedes Benz GLK350 has 2 batteries: a starting & auxiliary battery
• The starting battery is the vehicle's main power, responsible for starting the engine
• The auxiliary battery works as a backup by providing power to start/stop systems and other onboard technology to help put less strain on the main battery & alternator
