How to choose the right 36V battery
Choosing the right battery can sometimes be a little confusing. The information on this page will help you choose the right size battery for your products and tasks.
The differences between the types of 36V batteries
36V Lithium
If you love spending time in the garden and therefore require your tools to have longer runtimes, RYOBI 36V Lithium batteries are up to the challenge. You’ll find them ideal for practically every general gardening task.
36V Lithium HP™
For more complex gardening tasks that require even more power and longer runtimes, 36V HP, with larger 27100 cells deliver added power and increased runtimes. They’re engineered to enable you to push your garden tools harder for longer.
Making the right choice
What does the ‘Ah’ mean on a battery?
Performance and runtime – High Ah batteries provide longer runtimes and increased power to do more. This is often a requirement of power-hungry tools and products, like lawn mowers cutting long grass on a large lawn, a chainsaw cutting wood for a week-long campfire. They’re so powerful they make petrol power extinct!
Versatility and convenience - Low Ah batteries are a great choice for tools like a line trimmer or a hedge trimmer, where a lighter battery would deliver a comfortable experience over extended periods of use.
Finding the right 36V battery
36V battery range
RYOBI 36V batteries range from 2Ah right up to 12Ah. 36V batteries are compatible with RYOBI 36V products*.
*Refer to user manual

FAQs
Need more help? See below our FAQs to find answers to battery-related questions, troubleshooting tips and more.
RYOBI has a range of different amperage chargers - the higher the A (amperage) the faster the battery will charge. You can view our range of 18V chargers in the charger category on our website. Currently, the 8A Rapid charger (RC18180) is the fastest charger we sell.
You may not be using the right battery for your tool or project.
Where more power or runtime is required, larger amp hour (Ah) batteries are recommended. These batteries hold more charge and allow you to run higher powered tools, like circular saws, chainsaws and lawn mowers. The higher the Ah the more runtime you will get. For example, a 2.0Ah (RB1820C) battery will make 34 cuts* versus a 4.0Ah (RBC1840C) battery that will make 95 cuts* with a 18V HP™184mm Circular Saw (RCS18X).
*making cross cuts in 140mm x 45mm MGP10 yellow pine.
The 18V ONE+ 2.0Ah battery will work in circular saws, reciprocating saws, blowers or lawn mowers. But where more runtime and power are needed for longer, we recommend a minimum 4.0Ah battery.
How old is your battery?
Lithium batteries don’t last forever. Just like our phones and cars, batteries need replacing. If your battery is older than 3 years it might be time to purchase a new one and recycle the old one. You can also follow the tips below on how to get the maximum runtime and life out of your battery.
To obtain the longest possible battery life, always:
- Remove the battery from the charger once it is fully charged and ready for use.
- Don’t store batteries in tools.
- Store batteries in a dry, stable temperature environment.
- When fully depleted after use, make sure to charge it fully.
You may need to review the type of battery you’re using for your tool or project.
- Where more power is required for longer, we generally recommend bigger capacity (Ah) batteries for these projects. The 18V HP 5.0Ah (RB1850X) battery or larger batteries hold more charge and allow you to run tools for longer.
- If you experience very fast charge depletion of your battery, we recommend testing a different battery with your tool to see if it is isolated to that battery. If your second battery gets the same depletion, the job you are attempting may use more battery than you expected. Try using a larger Ah battery to complete the job.
If the issue is isolated to one battery, check the age of the battery (label underneath) and determine if it is time to retire/recycle it. If it’s still within the warranty period, take it back to the retail store along with your receipt or proof of purchase for warranty assessment.
There could be several reasons why your battery isn’t charging:
- Battery is too hot: If you've used your tool for an extended period and the tool is warm or hot, the battery may need to cool down to charge. When a hot battery is placed on the charger, the charger may indicate the battery is not ready to charge. Wait until the battery has cooled before attempting to charge again.
- Environment is too hot: Extreme temperatures, both hot and cold, can affect battery charging. Make sure you are storing and charging the battery where the temperature is below 27°C.
- Dirt or debris in the battery or charger contacts: Inspect the battery contacts on both the tool and the battery. Make sure they are clean and free from any dirt or debris. Clean with a dry cloth.
- Storing a battery when it’s flat: Store your batteries in a charged condition of a minimum of 2 bars of charge on the gauge.
- Tool or charger issue: Confirm and diagnose whether it is an issue with that battery specifically, or potentially an issue with tool or charger. Test the battery in question in different tools (or chargers if you have multiple) to isolate where the fault may be.
- Battery age: If your battery is older than 3 years it might be time to purchase a new battery and recycle the old battery. Batteries have a limited lifespan and can eventually lose their ability to hold a charge.
Flashing red: This indicates your battery is either too hot or too cold. When the battery reaches the necessary cooled or warmed temperature, the charger will begin flashing green in fast charging mode.
Flashing red and green: Battery or charger may be defective:
- If defective, try to repeat the conditions a second time by removing and reinstalling the battery. If the LED status repeats, try charging a different battery.
- If a different battery charges normally, it’s likely an issue with the battery.
- If a different battery also indicates ‘Defective’, the charger may be defective.
Flashing green: Battery is fast charging.
Fading green: Battery is being charged at a lower rate.
Solid green: Battery is fully charged and ready to use.
- If your battery or charger is older than 3 years it might be time to purchase a new one and recycle the old one. If it’s still within the warranty period, take it back to the retail store along with your receipt or proof of purchase for warranty assessment.
Solid orange: This indicates your battery is either too hot or too cold. When the battery reaches a cooled or warmed temperature, the charger will begin fast charging mode by flashing green.
Flashing red and green: Battery or charger may be defective:
- If defective, try to repeat the conditions a second time by removing and reinstalling the battery pack. If the LED status repeats, try charging a different battery.
- If a different battery charges normally, it’s likely an issue with the battery.
- If a different battery also indicates ‘Defective’, the charger may be defective.
Flashing green: charge in progress.
Solid green: Fast charging complete. Battery is ready to use.
The charging time for a RYOBI battery can vary depending on the size of the battery (Ah) and the charger (A) being used. RYOBI has a range of different amperage chargers - the higher the A (amperage) the faster the battery will charge.
For example, below are the average times a RYOBI 18V 4.0Ah battery will fully charge in different A (Amperage) chargers.
| 2A | 145 minutes |
| 4A | 80 minutes |
| 5A | 70 minutes |
| 8A | 45 minutes |
Charging Status Indicator: Many RYOBI chargers have LED indicators that show the charging status, which can be helpful to determine when the battery is fully charged.
No. Always remove a battery from the charger once it is fully charged to protect the battery from over-charging. Over-charging can damage the battery, reduce its lifespan, or possibly cause a safety hazard.
No, you cannot use a RYOBI 18V battery in a RYOBI 36V tool, and vice versa. RYOBI tools and batteries are designed to be used with specific voltage ratings, and they are not interchangeable.
A solid green light on your charger indicates that your battery is fully charged.
- Check for dirt and debris: Inspect the battery contacts on both the battery and the tool. Make sure they are clean and free from dirt or debris, as dirty contacts can affect the connection.
- Inspect for physical damage: Check the battery for physical damage, such as cracks or bulges. If the battery appears damaged, discontinue use, as damaged batteries can be dangerous.
- Environmental conditions: Consider the environment in which the battery is stored and used. Extreme temperatures, both hot and cold, can impact battery performance. Store and use the battery within the recommended temperature range.
Bunnings has a national battery recycling program; it is free and easy to use.
All stores have battery recycling units, making it convenient for RYOBI customers to drop off used batteries with confidence, knowing they’ll be recycled.
You can charge your battery any time.
Yes, RYOBI 18V batteries are backwards compatible with the majority of Ni-Cd or Ni-Mh tools.
RYOBI AU/NZ chargers can only be used in Australia and New Zealand.
Power supply in normal household voltage, 220V – 240V, 50Hz 60W.
Store the battery indoors where the temperature is below 27°C and not exposed to moisture. Do not store your battery in the charger as this may deplete the battery's charge overtime. Store the battery in a “charged” condition (minimum of 30%-50% charged). To charge the battery after a six-month storage period, it is recommended to discharge the battery to about 10% - 20% (1 bar, by running it in a tool) and charge afterwards to maximise the battery lifetime.
