Some lawn mowers require a battery to run their various features. If you are facing battery issues or notice a lack of charging, then you may ask: Will a lawn mower run with a dead battery?
This article will explain the answer. You can also learn how the battery system works and pro tips to keep it in good condition. So let’s scroll down to discover!
Will A Lawn Mower Run With A Dead Battery?
No. If your lawn mower solely relies on a battery, it can’t run with a dead battery. You have to replace or charge the battery for the machine to recover.
Riding lawn mowers generally require batteries to work. The batteries charge the spark plug to activate the engine. So if your lawn mower doesn’t start, follow these tips to check whether its battery is dying.
Examine the connections
Lawn mower batteries are vulnerable to significant vibrations, which can cause rapid deterioration of the power source. However, regular battery checks can help overcome this problem.
To access the lawn mower battery on your riding lawn mower, lift its seat. Then, gently pull the wires and tighten the loose ones.
Please remember that reliable electrical flow depends on secure connections. Sometimes, resolving a power issue is as simple as addressing a wire problem.
Charge the battery
Attach the doubtful battery to a charger and set it to the standard 12-volt rating. This rating ensures consumer safety by minimizing the risk of electrical shocks.
Then, let the charger energize the battery for about eight hours. If your battery still displays a low status after this period, you may need to replace it.
In this case, the battery cells can’t receive electrical energy as they once did. Persisting with them can’t help you solve the problem.
Check for weird sounds
When you start the lawn mower, pay attention to valuable insights into its condition. If you detect a clicking sound when turning the key or grabbing the pull cord, your battery needs replacement.
Verify the voltage
If you question the machine’s electrical system, specifically the use of your charger, check it with a multimeter.
Attach one of the meter’s probes to the terminals of the battery. Then, align the positive lead with the red terminal and connect the negative one to the black terminal. Typically, a functioning battery will register around 12 volts.
Check the water reservoir
The flooded design is common among lawn mower batteries. Hence, you can add water when maintaining the machine. Unfortunately, it may affect the battery.
So, examine the battery by checking the reservoir. You should fill it up to the highest point. Then, test your mower.
How Long Can A Lawn Mower Battery Sit Unused?
A lawn mower battery can sit unused for several months. Its lifespan depends on different factors, such as storage space and temperature.
It would be best to keep the battery connected to a charger when not in use. The charger can top off its charge and prevent power loss. This method also helps extend the lifespan of your battery.
You need to store your lawn mower battery during the winter. So check this video and learn more tips to do it properly:
What To Do If A Lawn Mower Battery Dies?
If a lawn mower battery dies, here are the steps you can take:
- Check if the battery is the root of the problem. You need to inspect the cables, terminals, and connections for any signs of damage or corrosion.
- Clean the battery terminals from debris. You can use water and baking soda for this task. Remember just to scrub the wire brush gently.
- Charge your battery. Follow the manufacturer’s instructions for the specific charger and battery. It usually requires several hours to complete.
- After charging, reconnect the battery and try starting the lawn mower. If the engine starts and runs smoothly, it suggests that the battery is charging properly. Starting the machine will be easier if you prime it frequently.
Tips To Keep Your Mower’s Battery In Great Condition
The lawn mower batteries should be in good condition to ensure the machine’s performance. Here are some tips to follow:
Keep the charging system clean
Your lawn mower works outside. Thus, it always comes into contact with debris, dirt, and grass clippings. The debris may penetrate the charging system, too, affecting the battery.
It’s essential to inspect and clean the charging system components regularly. If you see any corroded parts on the battery, clean them soon before charging.
Use float chargers when the battery is not in use
If you plan to store your mower for a long time, such as during winter, consider using a float charger or battery maintainer. Those devices provide a steady charge to the lawn mower battery. Hence, they can help maintain the battery’s optimal charge level.
Some people use a car battery charger for their lawn mower batteries. You can try this method, but please note that dangers may still occur.
Replace the battery or alternator when needed
Check the performance of your battery and alternator regularly. If you notice signs of a faulty battery, consider replacing it.
Similarly, the alternator may fail to charge the battery correctly. In this situation, consult the manufacturer’s recommendations or seek professional advice to determine the appropriate time for replacement.
The battery in your lawn mower plays a crucial role in making it work smoothly. If you encounter any relevant problems, don’t worry too much!
By understanding how the battery system works, you’ll be better prepared to fix any hiccups. So, take good care of your riding lawn mower’s battery. Then, you’ll be ready for all mowing sessions.
