They are also particularly great with the larger equipment that you will be enjoying for a variety of commercial or domestic applications without having to go through much.

They are offering some fun tools, and this 48V Mower is one such thing.

The 48V mover is a battery-operated full-sized lawn mower that you get to enjoy the best possible experience working with.

Ryobi 48V Lawn Mower Battery Problems

The lawn mower is basically a lawn mower that you can ride on and mow the lawn easily while having a ride around.

Not only its fun to be driving around, but you will also be able to mow large lawns without getting yourself tired.

The best thing is that it is battery powered, so not only you won’t have to worry about the fuel, but you will also be enjoying the green energy on it.

Yet, there are a few common problems that you might come across, and here are a few of them.

  1. Not Charging

The most common issue that you will need to deal with is the battery not charging for some reason.

There can be a lot of problems that will cause you to have this issue with the battery, but the temperature is the most common one.

These are lithium-ion batteries that you get on the Ryobi 48V lawn mower, and they need to be charged at an optimal temperature.


That is why if they have been under direct sunlight for some time, that can raise their temperature, and you will not be able to charge them.

Similarly, exposure to lower temperatures is also a possible reason for the batteries to not charge.

So, you will need to make sure that you are storing the batteries and lawn mower under shade in a dark and dry place, and that should help you to get rid of any such problems.

In addition to that, you will also need to keep it covered under extreme cold to not let the temperature affect it.

  1. Terminals getting carbon

While you are making it work, the lawn mower also has to deal with tons of moisture and more. That is why you will need to be careful about the moisture.

The grass might be getting wet due to rain, watering, or dew, and that moisture can turn to carbon on the terminals of your battery.

If you have carbon on the batteries of your lawn mower, that could lead to a few problems, including irregular power delivery and charging as well.

So, if you feel like you are getting irregular power delivery or having some problems with the charging, you will need to make sure that you are checking on the terminals.

If you find any such problem on the terminals, it would be better to clean it off properly using some sort of rubbing alcohol.

That would help you properly get the job done, and you will be able to make sure you will not have to face any such problems.

  1. Lowered Battery Timing

Another common problem that you will have to deal with has to do with lowered battery timing, it can be reduced over time.

That can happen due to multiple reasons, and you will have to check on it properly to get it sorted out in the right manner.

The batteries are wearable components, and if you have been using them for some years, it might be causing you to have this issue.

After getting the battery health checked, it will be better for you to replace the battery, and that will get you perfect run time on your battery.

There can be another problem with the battery swelling, and if that is the case, it could be due to overcharging. However, using the swollen battery is unsafe for you.

You should contact Ryobi to have that battery recycled properly and to get yourself a new battery to go with your 48V mower.

  1. Solenoid problems

It is not that rare for the solenoid between the battery and the starter to go bad after extended use. Luckily, the replacement here is not that expensive.

You will need a minimal budget to make use of this solenoid. So, if you’re struggling with the starter as well, know that the solenoid is to blame here.

The best thing you can do is take your unit to a repair center. The experts working there won’t take more than a few minutes to get through the fix.

However, if you’re not that sold on the repair fees, just go through the manual yourself.

From there, you need to remove the bad solenoid and install a replacement. Just make sure to disconnect the battery first and then go forward with the replacement.

Ideally, the issue will be fixed as soon as you change the solenoid in the system. However, if you find the contact points to be corroded, there is no harm in wiping the rust with a cleaner.

You can rely on a diluted vinegar solution to better manage the cleaning cycle. It all comes down to the effort you’re willing to put into managing this device.

  1. Alternator Issues

An alternator is the most crucial element when it comes to managing an electrical device. It is the primary source that charges your battery as you’re running the lawn mower.

So, if you are not really getting any uptime from the battery, the alternator is to blame here. Sadly, a bad alternator is of no use, and you can’t really fix it yourself.

So, replacing the alternator is the only real option in most situations. You will have to find a fresh piece to install in your machine to avoid further complications.

Most of the time, it won’t take you more than a few minutes to install the new alternator.

However, if you’re not sure about how to change the alternator, then hiring an expert will help you through this situation.

There is no harm in spending a few bucks on hiring an expert. So, refer to your local experts, and that would be it when it comes to alternator-related problems.

  1. Unit Won’t Hold Any Charge

The battery will sometimes run into problems with the charging levels. These issues are far too common for the Ryobi lawnmowers.

Even if you’re able to somehow charge the battery, it won’t hold any charge for more than an hour.

This situation almost always points toward a bad battery. The battery life of the unit can go down substantially over time.

This is especially true if you’ve never topped up your battery. So, if it has been a few years, and you can’t secure any response from the battery, buy a new one.

There is no guarantee that the new battery will be cheap. So, you’re not left with many options at this stage. It all comes down to the current situation of your lawn mower.

So, if it is a bit rough, just purchase a replacement. Here, your only focus should be on purchasing a fresh piece.

There is no point in only matching the power output, and you should only go with the battery that is recommended for your specific model.

Otherwise, you will be running into the same complications with the Ryobi battery.

Wrapping Up

Overall, these were some of the most annoying problems that you will run into while using the Ryobi system.

Even if you’re quick to follow through with the battery maintenance and there are no problems with the hardware, you can run into these issues.

Customer Support

So, Make sure to keep these fixes in mind if you can’t seem to get the desired response from the battery.

If you have just made the purchase, then the smarter thing to do here is to reach out to the dealer.

He will help you with a battery replacement, as these problems are covered by the warranty.

If you’re not sitting on a valid warranty, it is still a good idea to seek professional help. These people can save hours of your time, and you won’t have to isolate the issue yourself.

So, reach out to the dealer regarding these issues.

Hopefully, you will be able to grab a fresh battery by claiming the warranty on your Ryobi system!

  1. My ryobi54 zero turn total electric 5 month old
    Can not cut 2 1\2 acre lots without battery dying full charge at start never finishes it garages well taking care of but supper to cut 31\2 acres can’t cut 1

  2. OK, the Ryobi 48 volt battery system for it’s riding mowers is 4 12 volt AGM Gel ce3ll batteries not lithium ion. Their lithium, ion batteries are 40 volt and 80 volt.

  3. My Ryobi 480e has sealed lead-acid batteries, 100 ah. When new, I could often mow my entire yard on one charge. (A bit less than an acre, moderately hilly, numerous trees and other obstacles to mow around.) Now, three years old, one charge gets me about halfway, and the second charge may or may not quite finish the job.

    I opened the covers to check battery connections, etc. Aside from dust and dry grass, things looked pristine in there, no sign of corrosion. Is this just a normal decrease due to age?
