Why Do I Need A Lawn Mower Battery Charger?
A viable alternative to gas-powered lawn mowers, the ones powered by batteries have come a long way.
Most of them are powered by lithium-ion batteries, which are praised for their fast charging, high capacity, and increased power output.
These are the advantages that make it ideal for lawn mowers. The battery usually comes fully charged from the store and can last two to four weeks without a charge.
If this isn’t the case, you’ll need to charge it yourself, and this is where your battery charger steps in.
Moreover, whenever the battery runs out of charge, this device will help you refill it and continue working in the garden.
No matter how well you care for the battery, it will eventually lose its charge. But before it does, and this can be quite long, you can recharge and maintain it with the proper charger.
This charger is often versatile, i.e., it can also charge other rider batteries, including those of jet skis, ATVs, motorcycles, and more.
Most Important Features Of Battery Chargers?
Similarly, before we make a final verdict on other purchases, we need to consider the most important features of lawn mower battery chargers.
This is essential since there are a lot of poor-quality chargers on the market that are a waste of your money and time. Below, check out the things you should consider first:
- Power/Charging Capacity
Before anything else, you need to check whether the charger’s power output is compatible with your mower’s battery.
Usually, lawnmower batteries have a 6-12 voltage and 5Amp-25Amp amperage. When the charger’s charging level is higher, recharging the battery will be faster. That is, if you use the mower regularly, you may consider a charger with a bigger capacity, i.e., 6A or higher.
- Indicators
Many users aren’t even aware of this feature when searching for a battery charger for their mower.
However, it’s quite helpful. These indicators allow you to see the capacity level while it’s charging, so you can plan your next step.
All of the models we presented have this feature, which is great!
- Portability
If you need to carry the charger from place to place, a portable one seems like the best idea. It should also have a generous cord length. Look for a charger with a compact design and lightweight.
This ensures you can use it optimally, without having it locked in one place!
- Safety
Without a doubt, before you buy a battery charger, it’s essential to consider the safety features.
Make sure it’s equipped with overcharge protection, reverse polarity protection, and resistance to overheating.
When a battery charger lacks these features, the battery can get damaged!
- Matching with the battery
Before any other feature, most people check the voltage of the charger because if it doesn’t match the battery, the charging will not be proper.
The battery may also be damaged internally, or the worst-case scenario may happen: it may burst!
If the mower was manufactured after the 1980s, it probably has a 12V battery, so you’ll need a 12V charger, too.
Otherwise, you can choose a charger that can switch between 12V and 6V. These are highly versatile and ideal for use with any battery.
Still, they may have a higher price than other models.
- The price
Although it’s an important factor, many people ignore it. We shouldn’t, especially if our budget is fixed.
When checking out branded products, spending some more may be required. However, this doesn’t mean you can’t find quality chargers at a more reasonable price.
And, Amazon is a great place to find a lot of discounts.
What Kind Of Battery Charger Do I Need For My Lawn Mower?
As we previously mentioned, if your mower was purchased after the 1980s, it will need a 12V battery.
Thus, you’ll need a 12V charger too. But if the mower uses a 6V battery, opt for chargers that allow you to charge both 6V and 12V.
How to Charge the Lawn Battery the Right Way?
Before you begin charging the battery, you need to put on protective clothes, eyewear, and gloves. When ready, unplug the charger from the outlet.
Then, locate the mower’s battery, which is usually under the seat of the machine.
Now, you connect the positive charging cable of the charger to the red terminal of the battery. After this step, the next one is to attach the negative side too.
Then, it remains to match the voltages of the mower and charger and plug the mower into the charger’s main electrical outlet.
Can I Use The Car Charger For The Lawn Mower Battery?
If your lawnmower battery is lead-acid, you can use your car charger for it. The safest option is to use jumper cables.
On the other hand, if the mower’s battery is lithium, you can’t charge it with the charger for your car.
For this type of battery, you need a specially designed charger.
When Should I Replace The Old Battery Charger With A New One?
When the battery is empty, the charger revives it by recharging it and making it useful again.
But if the charger doesn’t work, filling the battery will be impossible. When the battery isn’t properly charged, you won’t get the runtime expected from it.
If this occurs, check the battery charger and determine if it needs to be replaced.
Here’s how you can do this:
- Plug the charger into an electric outlet
- Plug the test probes into a voltmeter
- Connect the battery of the mower to the charger
- Connect the battery’s positive end to the voltmeter’s red probe
- Connect the negative side with the black probe of the voltmeter
- Check the reading on the voltmeter
- If it’s pointed towards the right, the battery is getting charged properly
- If there’s no reading, the charger has to be replaced
