What does the ‘Ah’ mean on a battery?

All ONE+ batteries have an Ah (Amp-hours) rating printed on them. Think of this rating like the fuel tank in a car – the bigger the tank, the longer the runtime. RYOBI 18V ONE+ batteries range from 2Ah right up to 12Ah.

Because high Ah batteries provide a longer runtime, they are slightly larger and heavier than smaller Ah batteries. Higher Ah batteries are great companions for power-hungry tools and products.

  • All ONE+ batteries, including HP™, feature RYOBI’s IntelliCell™ technology, which means the battery can manage its own power and deliver optimum performance. Simply put, the battery monitors each cell, so it knows if some cells are working harder or are more depleted than others. It can then transfer the load accordingly onto other cells.  
  • When a ONE+ battery is being charged, the battery can identify which cells are depleted and can re-balance and charge these cells equally. The batteries will then be able to deliver improved runtime, more consistent power and greater durability.
  • 18V ONE+ batteries are great for DIY projects, general maintenance and repairs around the home, gardening, crafting and cleaning.

  • 18V ONE+ HP™ batteries are engineered to get the most from your ONE+ tools. These batteries are ideal for more complex DIY and larger gardening tasks where more power and longer runtimes are required. HP batteries have 2 additional terminals for advanced tool communication. This combination releases maximum power from the battery to the tool to complete the most demanding tasks. 
  • The 8Ah and 12Ah HP batteries have larger 21700 cells that are designed with lower internal resistance. This means they can deliver more power with less energy lost as heat. 
  • COOL CORE PRO™** – A heat management system that utilises heavy-duty, laser-welded cell straps and upgraded heatsinks to reduce battery operating temperatures, which helps to extend battery life.

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.

    2A145 minutes
    4A80 minutes
    5A70 minutes
    8A45 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.  

    1. 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. 
    2. 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. 
    3. 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.  

    *A small number of products are not compatible with the larger 8Ah and 12Ah batteries. See FAQs for more details.
