Types of Lawn Mower Batteries
- Lead-Acid Batteries: Most commonly found in gas-powered mowers. They come in conventional and maintenance-free variants. Conventional batteries may require periodic water refills, while maintenance-free batteries are sealed and safe from spills.
- Lithium-Ion Batteries: Gaining popularity due to their lightweight and longer lifespan. They charge quickly and perform well in various weather and operating conditions.
- AGM (Absorbent Glass Mat) Batteries: These are a subtype of lead-acid batteries but are sealed and spill-proof. AGM batteries offer better performance than conventional batteries and require less maintenance.
How Lawn Mower Batteries Work
Lawn mower batteries store electrical energy for the starter motor and other electrical components. When you turn the ignition key, the battery supplies power to the starter. The starter motor then cranks the engine, allowing the lawn mower to operate.
For electric mowers, the battery powers the electric motor directly. Most chargers operate on a preset voltage, ensuring safe charging. If the charger detects a fully charged battery, it automatically switches to trickle charge mode. Using compatible chargers prevents potential overcharging and extends battery life.
You can regularly check battery voltage using a multimeter. A voltage reading below the recommended level indicates a need for charging. Keeping terminals clean and free of corrosion helps maintain efficiency and performance.
