Rayovac Ultra Pro 9V Reclosable 12-pack

I try to use Rayovac batteries in my 6 smoke detectors if I can get them. I did use one of the other name brands but started to have some problems with them going dead before the year of smoke detector use was up. Since I started to use Rayovac....for the past 5 years, that has not happened. I don't have to worry about these going dead. As a matter of fact, they still have a lot of juice left in them at the end of the year, so I save them for my grandchildren to use in their controllers and such! Great Batteries At A Great Price!

now if amazon just package is actually correctly where the plastic box was crushed a little making the batteries be all over the box.aside from that, seems like a good deal. works ok for smoke alarms.

These work fine for smoke alarm batteries... they don't last but a day or two past 6 months... so be prepared for beeping in the middle of the night if you don't change them every 6 months on the dot. But they are cheap, and that's fine!

I use these in devices that don't require a lot of strength so they last just as long as the more expensive batteries. The price is good, so I'm happy.

I use these in electronic products i sell. Never had a defective battery so far. This is the best deal on the market.

quality batteries at a good price when needing several batteries at the same time such as replacing smoke alarm batteries thru the house at the same time

Good Battery

Great price on Rayovac batteries. I’m using them for my smoke/CO2 detectors. I’m not sure of how long they will last but for that price it was worth a try. Plus, I have enough left to replace them next time it is due. (I’ve always been a Duracell user)

Needed some batteries urgently for the fire alarm in my house and got them delivered the next day. No issues until now. Good packaging and quick delivery.

EXCELENTE PRODUCTO

Only used one battery so far, but it's working well. Bought the 12 pack of 9 volts.

Buy in bulk, it's less expensive in the long run. Good quality batteries.

That's all I know. First time I haven't owned this brand so I am hoping they have decent life. Seem like a good battery.
