Does Costco Have Lawn Mower Batteries?

Imagine this: You’re ready to tackle your overgrown lawn, but your mower sputters to a stop. You check the battery, only to find it’s dead. Panic sets in. You need a new battery, but where can you find one? Does Costco, your one-stop shop for everything from groceries to electronics, have what you need? This article will explore the world of lawn mower batteries at Costco, diving into the types they offer, their prices, and whether it’s truly the best place to buy your next battery.

In short, Costco does carry lawn mower batteries, but the selection is limited and depends on the specific type of mower you have. While their batteries may not be the most comprehensive or specialized, they are known for their competitive pricing and reliable quality. Let’s break down what you need to know about buying a lawn mower battery at Costco.

What Kinds of Lawn Mower Batteries Does Costco Sell?

Costco’s lawn mower battery selection varies by location and season, but you can generally find two main types:

1. Lead-Acid Batteries:

These are the traditional, more affordable option. Costco typically offers lead-acid batteries in various sizes, suitable for older mowers and basic models.


  • Lower price: Lead-acid batteries are generally cheaper than lithium-ion options.
  • Widely available: You can find them at most automotive stores and retailers, including Costco.


  • Heavier: Lead-acid batteries are heavier than lithium-ion batteries, which can make them difficult to handle and install.
  • Shorter lifespan: They typically last for 2-3 years, compared to the longer lifespan of lithium-ion batteries.
  • Maintenance required: Lead-acid batteries require regular maintenance, such as topping off the electrolyte levels.

2. Lithium-Ion Batteries:

These batteries are becoming increasingly popular due to their lighter weight, longer lifespan, and faster charging times. Costco carries lithium-ion batteries for specific brands like Ryobi and Ego, but the selection may be limited.


  • Lightweight and portable: Lithium-ion batteries are much lighter than lead-acid batteries, making them easier to handle and install.
  • Longer lifespan: They typically last for 3-5 years, offering more value in the long run.
  • Faster charging: Lithium-ion batteries charge much faster than lead-acid batteries.


  • Higher price: Lithium-ion batteries are more expensive than lead-acid batteries.
  • Limited availability: Not all retailers carry lithium-ion lawn mower batteries, so you might have to search specifically for them.

Where Else Can You Buy Lawn Mower Batteries?

If you can’t find the right battery at Costco, consider these alternatives:

Tips for Buying a Lawn Mower Battery

To ensure you get the right battery for your mower, consider these factors:

  • Battery type: Determine whether your mower requires a lead-acid or lithium-ion battery.
  • Voltage: Check the voltage of your current battery and make sure the replacement battery has the same voltage.
  • Battery capacity: The battery capacity is measured in amp-hours (Ah). A higher capacity battery will provide longer runtime but will also be heavier.

  • Warranty: Choose a battery with a good warranty for peace of mind.
