    Hyper Tough 20V MAX Power Share power tools use lithium ion (Li-Ion) battery packs. See "<a href="/myink/ViewPage.php?file=docs/Power%20Tools/Battery%20Conversion/Power%20Tools%20Battery%20Conversion%20Guide#18v20vNotes">Notes on 18V/20V Lithium Ion Battery Packs</a>" section in the "Power Tools Battery Conversion Guide" page.

<h3>Hyper Tough 20V MAX Power Tool Pin-Out</h3>

<p>
The Hyper Tough 20V MAX power tool interfaces with the +, T, and - terminals on the battery. But when we masked out the T terminal on the Hyper Tough 20V Max 8" 2.0Ah 20V Battery Powered Cordless Pole Saw, we have found that the pole saw still operated.
</p>

<p>
This means that it will be really easy to interface any other brand's 18V/20V lithium ion battery pack with some Hyper Tough power tools.
</p>

<p>
There is possibility that there are other Hyper Tough power tools that utilizing the T terminal. If your power tool doesn't operate without the T terminal, please see the battery section below.

<h3>Hyper Tough 20V MAX Battery Pin-Out</h3>

<p>
The photo below shows the pin-out on the battery.

<ul>
  <li>+ is the battery positive terminal.
  <li>The unmarked pin is the charging terminal. (See next section.)
  <li>T is probably the NTC thermistor temperature sensor. NTC stands for Negative Temperature Coefficient.
  <li>- is the battery negative terminal.

<h4>Resistance Measurement on the Battery</h4>

<p>
It's possible that other Hyper Tough power tool may utilize the T pin for identification. So we measured the resistance of the Hyper Tough battery and present it below:

</center>

<p>
As you can see above, the negative and the T terminal has 11.12 kilo-ohms resistance. Whether this information is useful or not, we don't know, because we don't have a Hyper Tough tool that needs it. But if it does help you, please feel free to let us know in the comments.
</p>

<p>
In most cases, it's the T terminal and the negative terminal that's important. After all, the negative terminal serves as ground or common. But in rare cases where the positive terminal is connected to the T terminal, we present the resistance measurement below:

</center>

<p>
Based on the resistance measurement, the positive terminal is not connected to the T terminal at all.

</center>

<p>
As you can see from the photo above, the charger is only connected to the the negative pin and the unmarked pin on the battery.
