Dear Mr Jones,
Thank you for your valued feedback. We're sorry that you encountered an issue with the Electra Blinds rechargeable battery system. While our rechargeable battery system works excellently for the majority of installations, as discussed, regrettably batteries will fail if subjected to extreme heat over time and therefore we recommend the blind batteries should be positioned out of direct sunlight where possible. Regrettably, due to the nature of your glazing and the architecture of your property, this was not possible.
We're really glad that we could eventually find you a long-term solution so you can continue to enjoy your Electra Blinds!
Kind regards, The Electra Blinds Team
