    Convenient Twin Pack

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    This 9V battery comes as a twin pack. I needed to replace the battery in our smoke detector every year and it uses only 9V batteries. Since these come in twin packs and the newer version can retain their power for 5 years (in storage), this will save me a trip to the store next year and not have a lapse in the detector's operation. Power retention is key for my purchase.

    Use to purchase only Duracell. Found out Duracell was owned by P&G. Won’t bring any P&G products into my household so I gave Energizer a try. Great batteries. Long lasting in all my devices – mice, remotes, etc.

    So glad I found this battery at best buy for my smoke detector. Worked great. I went to other stores and it was out of stock. Best buy is good at replenishing their items.

    I like being able to buy a long-life 9 volt batter battery in a two-pack. I don’t use a lot of them, but it is nice have a spare available when I need one.
