FAQs
1. How do I know what size battery my riding lawn mower needs?
The easiest way to know what size battery your riding lawn mower needs is to check the owner’s manual. The manual will provide specific details about the battery type, voltage, and cold cranking amps (CCA) required. You can also check the battery itself for the necessary information. If you don’t have the manual, you can contact the manufacturer or a local lawn mower repair shop.
It’s important to remember that using a battery with the wrong specifications can lead to problems with your mower’s starting and performance. Using a battery with too low of a CCA rating might not be able to provide enough power to start the engine, while using a battery with too high of a CCA rating might be incompatible with your mower’s electrical system.
2. What are the most common battery types for riding lawn mowers?
The most common battery types for riding lawn mowers are lead-acid batteries, specifically flooded lead-acid batteries and AGM (Absorbent Glass Mat) batteries. Flooded batteries are the most affordable, but they require regular maintenance to ensure proper hydration. AGM batteries are sealed and require minimal maintenance, making them a good choice for those who don’t want to deal with filling them with water.
There are also lithium-ion batteries, but they are more expensive than lead-acid batteries and not as commonly used in riding lawn mowers. However, they offer benefits like faster charging times, longer lifespan, and less weight.
3. What is the difference between CCA and AH?
CCA (Cold Cranking Amps) measures the battery’s ability to start an engine in cold weather. A higher CCA rating means the battery can deliver more power in cold temperatures. AH (Amp-Hour) measures the battery’s capacity to deliver a continuous current for a specific duration. A higher AH rating means the battery can provide power for a longer time.
Both CCA and AH are important factors to consider when choosing a battery for your riding lawn mower. You need a battery with enough CCA to start your mower in cold weather and enough AH to power it for a full mowing session.
