With VELUX not offering a replacement battery for all solar window motors produced after 2014 it has meant the whole motor/battery assembly needs to be replaced.
We have worked with a UK battery manufacturer to produce identical battery packs and have successfully replaced batteries in many roof windows in our local area.
Contact us for a quote on battery replacement for your windows or visit our ebay store to purchase batteries to install yourself.
