My battery is 18V (or 20V) and I want to use it on a 20V (18V) tool. Is that okay?

Yes. 18V and 20V packs are effectively the same class: both typically use five 3.6V cells, read about 21V when fully charged, and around 15V when depleted. The small labeling difference doesn’t matter in practice, so you can use an 18V battery on a 20V tool and vice versa when using the appropriate adapter.

Are there any precautions with batteries that lack safety components?

If your battery does not include built-in monitoring, avoid fully discharging it. Stop usage around 20% remaining to help maintain performance and longevity.

AEG 18V to Hikoki 18V Battery Adapter

Q: Will the battery adapter damage my battery or tool?

No. The adapter is designed to provide a safe, reliable connection between compatible batteries and tools when used as directed.

Q: What about different brands and their battery safety components?

Brands can differ in where they place monitoring and safety components. Some (for example, Ridgid/AEG) integrate monitoring in the battery, while others include it in the tool. This is normal and accounted for in compatibility guidance.

Q: Can I charge my battery with the adapter?

No. The adapter is for tool operation only and is not a charger. Do not use it with tools or devices that attempt to charge a battery (such as certain radios with charge-through features).

Q: Can I trust the reliability of your battery adapter?

Yes. The adapters are tested against strict quality standards for safety and reliability. If you ever have an issue, contact support at support@powertoolsadapters.com and we will help.

Q: Will the adapter I receive look exactly like the one in the pictures?

Minor visual differences (such as color or finish) are possible because functionally identical versions may be used. You will receive the correct model for the battery and tool combination you selected, with the same compatibility and performance.

Q: My battery is 18V (or 20V) and I want to convert to a 20V (18V) tool ?

Let's dive into the intriguing world of power tool batteries and voltage ratings. You may have noticed batteries labeled as 18 volts or 20 volts (or even 19.2 volts!). Surprisingly, these batteries are practically the same despite the apparent difference. The truth is, manufacturers use these voltage numbers as a catchy marketing strategy to grab your attention. They slap a 20-volt label on it to make it sound more powerful and exciting.

Here's the reassuring part: both 18V and 20V batteries are made up of 5 cells, each having a voltage of 3.6V. When fully charged, they average around 21 volts and drop to around 15 volts when depleted. The reason manufacturers go with 18V is because it's the nominal voltage.

Now, here's the important bit: the small voltage difference between the two doesn't really matter when using a battery adapter. In fact, you can safely use an 18-volt battery with a 20-volt tool, and vice versa. So, don't worry about mixing them up—they'll work just fine together!

Q: Will the battery adapter damage my battery or tool?

Absolutely not! Our battery adapter is specifically designed to ensure the safety of both your battery and tool throughout usage.

Q: What about different brands and their battery safety components?

Different brands may vary in terms of battery safety configurations. Brands like Ridgid/AEG have integrated the battery monitor and sensor within the battery, while other brands have placed these components in the tool itself.

Q: Can I charge my battery with the adapter?

Our battery adapters do not support charging capabilities, and they are not compatible with tools that have a charging function, such as a radio that can charge a battery.

Q: Are there any precautions I should take with batteries without safety components?

If your battery lacks these safety components, we recommend not fully discharging it and ceasing adapter usage when the battery reaches around 20% charge. This precaution ensures optimal performance and longevity.

Q: Can I trust the reliability of your battery adapter?

Absolutely! Our battery adapter undergoes rigorous testing to meet stringent quality standards, ensuring a safe and reliable solution for expanding the compatibility of your power tools. Rest assured, your satisfaction and safety are our top priorities. In the rare event that any issues arise, our dedicated support team is here to assist you. Feel free to contact us at support@powertoolsadapters.com, and we'll be happy to help resolve any concerns you may have.

Remember, your satisfaction and safety are our top priorities. Enjoy worry-free usage and explore the expanded possibilities with our trusted battery adapter.

Q: Will the adapter I receive look exactly like the one in the pictures?

While we always strive to show accurate product images, the adapter you receive may differ slightly in color or finish. This is because we sometimes ship functionally identical models that meet the same compatibility and safety standards but are manufactured with different casing materials or colors.

Regardless of visual differences, you will receive the correct adapter for the battery and tool combination you selected. Functionality and performance will always match your order specifications.
