    It’s great to buy the value pal to keep a few batteries on hand, rather than waiting for a battery to die and then go out to buy a replacement. These batteries have a really long life, reasonably priced.

    9v Batteries - Excellent

    If you need something powered, and it holds 9v batteries, well then you're in luck! Get you some of these bad boys, pop 'em in and BOOM. You're up and running man. Full speed. Usain Bolt style. There's no quit in these bad boys. When you need one yard on 4th and 1 from the goal line, these 9V's are scoring a touchdown every time. If you buy any other batteries, you're making a grave mistake.

    I got these to replace a smoke alarm battery that died. At the store, a 9V battery is like $6, so I figured I'd pay a little extra to get 4. I never have extra 9V batteries, so I thought it would be nice to actually have one handy next time I need one. As other reviewers stated, this does not come in original packaging - these came as two small baggies, each with two 9V batteries. I only tried out one of the batteries so far, but it worked just fine.
