We use them in phones, computers, toys, and just about anywhere we need power, but don't want to plug into a wall socket.
We're talking about batteries of course.
A lot of people will tell you it's a difficult national economy right now, but while some businesses fail, Sonia Lee of Batteries Plus says the Battery Biz is good.
" As you think about it, more things are portable. Your laptops, your cell phones, and portable offices have taken more and more battery use over the years. So we've become a great supplier of replacement batteries," said Miss Lee
They started with one Batteries Plus store in Huntsville. Then expanded to Florence, then a second store in Huntsville. Next up a Decatur location scheduled to open in November.
In total this locally owned business carries over 30,000 types of batteries, and close to 10,000 different kinds of light bulbs.
" Some of the more interesting items we have at Batteries Plus is a defibulator battery. So not only do we have your everyday common batteries, but we have some specialty items as well."
Small or Large they probably have it when it comes to batteries and light bulbs, they also have a tech center to design, assemble, rebuild and test custom batteries.
" We have an in house tech center where, everybody has cordless drills..... We open the cordless drills up and replace the cells and make it as good as new."
