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

A great product. No mor buying expensive lithium batteries.

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.

Works perfectly. Replacing a tube battery pack.

Our wide Somfy shades chewed through AA batteries in a hurry, and this can go for months without a recharge. Also drives the shades faster than the alkaline batteries. A good investment.

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).

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.

Good choice to eliminate batteries.

Good batteries which last a good while on a charge. Don't let them sit discharged though - needed this replacement as my 1.5 year old battery had died and wouldn't charge as it was allowed to run completely flat.

Much better than having to replace the individual lithium batteries, this only requires charging after several months

Its a battery, it stores electricity. Expensive for what it is but does the job.
