For advanced repairs or DIY charging, some models feature internal contact points (labeled C1 through C4) that represent the individual cell banks in the 5S (5 series) configuration: Usage Notes for DIY Adapters Simple Power To better understand the Hart 20V battery pinout

: If the battery flashes codes when you press the status button, it may indicate 0-10% charge , Temperature Out of Range , Over Current , or Permanent Failure . Checking resistance between the (T) pin and (-)

Checking resistance between the (T) pin and (-) pin can tell you if the internal heat sensor has failed. 3. Battery Adapters

The Hart 20V battery utilizes a 5-pin interface designed for power delivery, temperature monitoring, and communication with the tool or charger

The "better" news is that HART is compliant with the "One+ 20V" standard. In fact, many hobbyists have discovered that the . They likely share the same OEM manufacturer (TTI). Therefore, a better understanding of the HART pinout means you also understand how to repair Porter-Cable and some older Ridgid batteries.
