Direct replacement for Velux KSX 100K solar window

This 10.8V 2000mAh Ni-MH pack matches the original GP2100AFHT and HHR-210AH specifications. It suits owners of Integra Solar, Rolladen and Solarfenster models who need a certified drop-in power source.

Simple two-wire swap with no soldering required

The pack slides into the existing compartment once the old cells are removed; polarity markings on the housing prevent reverse insertion. Installers sometimes forget to fully seat the connector, which leaves the shutter unresponsive until the plug clicks home.

Holds charge through weeks of cloudy weather

The 21.6Wh capacity keeps the motor running for multiple daily cycles without mains top-up. Self-discharge stays low during seasonal inactivity, so the shutter operates reliably when sunlight returns after extended overcast periods.

Questions about this item

How can I verify the battery is working after installing it in my Velux KSX 100K solar roller shutter?

The window should operate smoothly on solar power alone; the control panel will show normal charging status and the motor will run without mains connection.

What comes in the box and do I need any extra parts to fit this replacement?

The package contains one 10.8V 2000mAh Ni-MH battery pack measuring 71.3 x 54.2 x 27.0mm and weighing 279.0g; no additional components are required for installation.

Which compatible part number should I choose between GP2100AFHT, HHR-210AH, 832817, GP210AFHT and 865103?

All listed part numbers — GP2100AFHT, HHR-210AH, 832817, GP210AFHT and 865103 — refer to the same 10.8V 2000mAh specification, so any match confirms the correct battery.
