Not the Mazda you think it is. Piles is batteries, and Mazda Cipel is the manufacturer name. Mazda in 1914, but I am not sure when they joined Cipel...here is a Wikipedia page that has a version of the sign, but the website below that has a more extensive history for some one who speaks French (I am rusty) or who gets creative with google translate. There are a number of these signs on e-bay.

Looks to be a lamp company that expanded into batteries (piles). Batteries were called piles from the original 'true' battery "The voltaic pile consisted of pairs of copper and zinc discs piled on top of each other, separated by a layer of cloth or cardboard soaked in brine (i.e., the electrolyte)." from Wikipedia.
Later actual working batteries (developed in the late 1800's) had to be recharged, so that is probably what the service on the sign refers to, letting folks know that their batteries could be serviced at the location the sign was posted (en vente ici).
For more detailed info on the company go to this website: http://les-anciens-de-la-pile.fr/accueil.php:
I have printed the first paragraph for you (in English) from the above website.
After the start of the production of electric batteries: Leclanché in 1867, Hydra in 1899, Mazda in 1914, Wonder in 1916-1917, Carbone Lorraine in 1921, and after many adventures, three large companies supply French batteries, civil and military , In the years 1950-1960. If Wonder is constantly expanding, Leclanché has been bought out by Saft and Cipel-Mazda brings together Hydra, Mazda and Carbone Lorraine batteries
