Honestly, this store is another place that has saved my sanity time & time again. Apparently, battery testers(the kind that you can see if a AA or AAA battery is still good) are not sold at Lowe’s & at Wal-Mart. Thankfully, I found one here for less than $ 10. It’s a tiny store that has a variety of electronics. If you can’t trek all the way to a Best Buy or to a Micro Center this store is quite convenient. In & out very fast. Very helpful staff. Wide range of prices, but generally less than what you pay at Best Buy. Not only that, better quality.
