Lawn Mower Battery: How Long Do Lawn Mower Batteries Last?
When spring and summer roll around in Calgary, it's time to pull the lawn mower out of storage and get to work. But before you start cutting grass, it's important to check one essential component—the lawn mower battery.
Whether you own a ride-on mower or an electric push mower, the battery plays a vital role in keeping your equipment running smoothly. But how long do lawn mower batteries last? And what can you do to make them last longer?
Let’s dive into everything you need to know.
Average Lifespan of Lawn Mower Batteries
Typically, a lawn mower battery will last between 3 to 5 years. However, the exact lifespan depends on how you use, maintain, and store your battery—especially during Calgary’s long and chilly winters.
If your battery is over 3 years old and you're noticing starting issues or power drops, it's likely nearing the end of its life.
Several factors affect battery life:
- Type of battery (lead-acid, AGM, or lithium-ion)
- Frequency of use
- Charging and discharging habits
- Weather conditions (especially winter storage in Calgary)
- Maintenance and care practices
Types of Lawn Mower Batteries & Expected Lifespan
Different mowers use different types of batteries, and each comes with a unique life expectancy.
1. Lead-Acid Batteries (3 – 4 Years)
These are the most commonly used batteries in ride-on or garden tractors. They are cost-effective but require regular maintenance like checking water levels and cleaning corrosion.
- Pros: Affordable, widely available
- Cons: Heavier, needs maintenance, sensitive to cold
- Tip for Calgary: Extreme cold can drain lead-acid batteries. Store indoors during winter.
2. AGM Batteries (Absorbent Glass Mat) (4 – 5 Years)
AGM batteries are a step up from standard lead-acid. They are sealed, maintenance-free, and better equipped to handle the vibration and cold temperatures typical in Calgary.
- Pros: Longer lifespan, maintenance-free, spill-proof
- Cons: Slightly more expensive
- Best For: Those who want low-maintenance, durable options
3. Lithium-Ion Batteries (5 – 8 Years)
Used primarily in modern electric push mowers, lithium-ion batteries are lightweight, quick-charging, and long-lasting.
- Pros: Long life, fast charging, lightweight
- Cons: Higher initial cost
- Ideal For: Eco-conscious homeowners or those with smaller lawns
Signs Your Lawn Mower Battery Needs Replacement
It’s important to recognize the early signs of battery failure before you’re left with a dead mower in the middle of your yard.
Look out for:
- Slow or no start: Mower struggles to crank or doesn’t start at all
- Battery won’t hold charge: Requires frequent charging
- Visible corrosion: White or green residue on terminals
- Frequent jump-starts: A clear sign of a failing battery
- Battery age: If it's over 3 years old, performance may start dropping
If you're experiencing any of these issues, it may be time to visit Batteries Store Calgary for a replacement.
How to Extend the Life of Your Lawn Mower Battery
Taking good care of your battery can save you money and frustration. Here are simple ways to get the most life out of your mower battery—especially in a city like Calgary where weather extremes can take a toll.
1. Charge After Every Use
Don’t wait for the battery to go dead. After mowing, plug in your battery (especially lithium-ion types). Keeping it charged prevents deep discharge, which shortens battery life.
2. Store in a Cool, Dry Place
Leaving your battery in a freezing garage all winter? That’s a big no-no. Cold temperatures can drain and damage it. Always store batteries indoors during the off-season.
3. Disconnect During Winter
If you're not using your mower for months (like in Calgary’s winter), disconnect the battery and bring it inside. This prevents parasitic drain and potential damage from freezing.
4. Use a Battery Maintainer or Trickle Charger
A smart charger will keep the battery topped up during storage without overcharging. It’s a great tool for keeping your battery ready-to-go in spring.
5. Clean Terminals
Corrosion buildup reduces performance. Use a wire brush and a mix of baking soda + water to clean terminals every season.
When Should You Replace Your Lawn Mower Battery?
If your battery is older than 3–4 years, it’s wise to have it tested before mowing season.
Calgary’s short summer window means you don’t want to waste any time jump-starting or waiting for a replacement mid-season.
