According to pinout measurements:
Storing batteries in very hot or very cold environments can degrade the chemistry of the cells. Aim for a cool, dry place.
For those looking to repair or manually balance the battery, there are internal contact points (often labeled C1 through C4) that correspond to individual cell voltages: Key Technical Insights Voltage Logic hart 20v battery pinout diagram better
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
: Higher-demand tools like vacuums or drills may use a specific "low power" positive pin to detect when the battery is drained, preventing damage to the cells. According to pinout measurements: Storing batteries in very
A pinout is a diagram showing the function of each electrical contact (pin) on a device's connector. The Hart 20V battery uses a 5-pin interface that, like most modern smart batteries, does much more than just supply positive and negative power.
The pinout for a typically consists of 5 main pins plus several internal contact points for balanced charging. When looking at the battery with the connector facing you, the layout generally follows this configuration: A pinout is a diagram showing the function

Over time, oxidation can occur. Use a small wire brush or emery cloth to clean the terminals to ensure a solid connection.
