Velux solar window battery pack 865103 nimh 10.8v / 2100mAh type GP210AFHT for velux solar windows 2014 onwards.

Velux will advise to change the motor and panel with their kitset as sometimes it is the panel at fault, their new design panel will not work on its own with the old motor, hense the need for this expensive option, we now sell the battery on its own, 9 times out of 10 it is the battery as these nimh batteries have a limited lifespan.

To replace, remove the motor, unplug the solar panel cable and battery cable, then with a flat blade remove the cover from the battery housing, pull the battery out and swap, replace cover, plug leads in and refit, really simple, some windows will need pairing with the remote if left for a long time without power!

For replacing batteries on older solar windows you will need to reuse the 4pin block and use a wago connector on the brown and white wires.

Genuine Velux part (not a cheap copy) 2 year Velux warranty, currently 3 week lead time.
