Bought this as velux solar window had stopped responding. Velux suggested replacing the entire mechanism for £348. The original rechargeable batteries were dated 2017 so though I’d try a replacement for a much cheaper price before forking out for a complete overhaul. Window now works again with this replacement battery pack for a fraction of the price.

Fast delivery of replacement battery for my solar powered Velux window. Easy to fit and much cheaper than buying the Velux replacement unit. I have now replaced batteries on all three Velux windows with batteries supplied by subtel. They were also very quick to supply a replacement free of charge when one of those packs supplied did t work
