Rechargeable Battery Pack for External Battery Wirefree Motors - Year-Round Power for RTS Motorized Shades, Curtains, Awnings - Charge Once a Year - #9021217

Works perfectly. Replacing a tube battery pack.

Best replacement for AA battery packs that drive powered shades. Holds charge for extended periods - I have tested them up to three months without charging. Also very easy to install.

A great product. No mor buying expensive lithium batteries.

You have to pay Somfy for the usefulness of the product (these are overpriced for what they do). I'm an older guy and I didn't want my spouse, when I'm gone to struggle with the battery changes on our electric blinds. So, here's the solution. These units will work. To keep from mounting them, instead, I put a decorative Ikea shelf over each window (4). My wife gleefully shopped for nice pictures for the kitchens (2) and made the kitchens pretty. Here's where this Somfy rechargeable unit fits in... it can also just lay on the the Ikea shelf, out of sight. When the battery needs recharging, just unplug and charge it. When done, place it back on the shelf and plug it in. Simple... even us older folks can do it. That's one more thing that I won't have to "worry" about if I become disabled (it's more strenuous to do as you age). If you're young, healthy and strong, you can still used the tubes (which are connected in parallel to last two years instead of one).

Good choice to eliminate batteries.

We have 12 sets of blinds and love using them. But hated buying new batteries all the time. This rechargeable battery is terrific! We're replacing all of the old style with these. Easy to install and rarely needs recharging. Wish we'd known about them sooner!

They work and hold a decent amount of time.However one stopped taking charge and tried as many troubleshooting steps to no avail. Warranty for 5 years ( mine are less than 2 years old) impossible nto get though a section in the app to assist or getting instructions for an exchange.

Works great, even with a single one replacing a double battery tube. The newly designed charger also good as it made the charging fitting far more sturdy than the original one. I've replaced all the battery tubes in a room with these. With the price increases of Lithium batteries, these will pay for themselves within 18 months.
