What batteries do Hunter Douglas shades take?
Twelve AA batteries in the 18V wand. Eight AA in the 12V wand, which Hunter Douglas fits to headrails built for an eight-cell wand: Duette, Applause, Silhouette and Vignette shades ordered with eight batteries, Parkland and EverWood blinds from 2018, Palm Beach shutters, and most PowerRise 1.0 shades. The PowerRise 1.0 exceptions: Vignette made before May 2010 converts to the 18V wand (twelve AA) plus power cable 2920247000, and Silhouette and Nantucket made before May 2010 convert with Hunter Douglas kit KIT9112, which takes eight AA. No other size, and no rechargeable pack unless your shade was ordered with one.
Count the batteries in your old wand if you are not sure which you have — twelve or eight tells you everything.
How long should they last?
Between nine months and two years, and the spread is not random. Four things move it:
How often the shade runs. A shade on a twice-daily schedule does about 1,400 cycles a year. One you touch occasionally might do 200. That alone is most of the difference.
How heavy the shade is. A wide Provenance woven wood pulls far more current than a small Duette. In the same house, on the same day, the heaviest shade dies first and it is not a fault.
Temperature. Alkaline cells lose capacity in the cold and vent in the heat. A wand in a sunroom has a harder life than one in a hallway.
Whether the cells are matched. This is the one people get wrong, and it is the subject of the next section.
Why does one cheap battery ruin eleven good ones?
Both wands wire the cells in series. The current that flows through the string is limited by the weakest cell in it — so twelve batteries behave like the worst one of the twelve, and eight like the worst of the eight.
That has three practical consequences:
- Never mix brands. Different chemistries have different internal resistance.
- Never mix old and new. A fresh cell next to a half-dead one is wasted.
- Replace the whole set at once, every time, even if some still test fine.
A bargain twelve-pack is not twelve cheap batteries. It is one cheap battery, twelve times over, and the shade performs like the worst of them.
Which battery brand should I use?
Hunter Douglas specifies Duracell or Energizer alkaline, and that is what we would use. It is not brand loyalty — it is leak resistance. Both carry a leakage warranty, and leaking is the failure that does permanent damage.
Store-brand and no-name cells are the ones we see leaked inside dead wands. The saving is about four dollars. The wand it destroys costs twenty.

Which way do the batteries go into a battery wand?
There is an orientation diagram printed on the tube. Read it.
Because the cells are in series, one battery inserted backwards is charged by the others. Hunter Douglas warns that this can damage the wand or make the batteries leak; on the 18V wand it blows the fuse in the end cap, and that fuse is not serviceable. With leaked cells it is one of the two ways a working wand becomes a dead one, and it happens most often to people who have done it a dozen times before and stopped looking.
Is there a charger instead of batteries?
Not for an AA wand — it has no cell to charge and no socket to charge it through. Hunter Douglas does make a separate rechargeable wand, which is a different part. Is there a Hunter Douglas battery charger? covers how to tell which kind you have before you buy the wrong thing.
What if new batteries do not fix it?
If a full set of fresh matched cells changes nothing, the batteries were not the problem. There is a short list of reasons for that, and two of them cost nothing to fix: shade not working after changing the batteries.
Or work through the six-symptom check — three symptoms mean the wand has failed, and three mean something else entirely that a new wand would not fix.
If it is the wand, find your shade line and we will have the part.
