Battery care and safety
- When it shuts down for cold
- Shuts down in the cold to protect lithium
- Operating temperature range
- -20 to +60 °C, derating above 40 °C
“To prevent damage of lithium batteries the charger will turn off automatically at low temperatures.”

Compatibility
- How it knows the engine is running
- A detection mechanism, not a voltage threshold
- Why a smart alternator defeats that threshold
- A smart alternator can run below the threshold
- Battery voltage it runs on
- 9 to 17 V in
“An integrated mechanism detects whether the engine is running (engine shutdown detection), which only activates the charger when the alternator supplies power.”

“This is especially significant in the case of vehicles with a Euro 5 or Euro 6 smart alternator, which often supplies too low charging voltage even when the engine is running or when extended cable lengths, as is often the case in boats and RVs, lead to voltage drops.”
