what kind of batteries

Excellent question! I had to pry open the unit to find out. My recollection is that the timer arrived with a small plastic tab. I must have pulled the tab to activate the battery. The battery is well sealed, with a VERY tight fitting cover, held in place by a small Phillips screw. I will add a Dymo label on the back, for when it becomes time to replace the battery.

The Big and Loud uses a single 9Volt battery. Love it! It is Big, Loud, durable, strong magnet and stand.Thanks--Ken

It uses a 9 Volt battery which, with normal use, should last for over a year. I absolutely love this timer!

I use surefire 123A batteries (SF12-BB Box of 12 Bat). They are very good and cheaper than most other brands.

Batteries come in all shapes and sizes. Any 7.2+V battery will work, if it fits. You may also need to replace the connector or make/buy an adapter.

They take three round tiny (wee) batteries, called SR41 Silver cells. Hopes this helps!

They are 18650 Batteries. Amazon has plenty of choices. You will likely need a charger for them also. Decent flashlight - worth the extra dollars for the batteries and charger to round out the set!!

Any brand as long as they are NiMh batteries. Just be sure that they are not old NiCads.

I purchased one last Christmas. I don't remember what kind of batteries it needed. It did work great.

This model specifically uses a CR-2032 battery. If you are unfamiliar with them they are the flat round batteries about the size of a dime just a bit bigger in diameter and a bit thicker than a dime.

I don't know, but I suspect they were older batteries when I received them because they did not last very long

A cr123 3volt battery. They can be pricey if purchased one at a time but reasonable if purchased in bulk.

Any AA batteries will work, I used regular ones and they are still working two months later

Look for the ones with the AC plug those work well, those kinds have a good output (usually) I find the ones with 1 amp output are good for these batteries

2 - 3Volt 123A Batteries. You can use any type but I prefer the Surefire Brand myself.

Regular or rechargeable batteries work in these. Nothing special is needed. If they aren't working, they're probably defective. That happened with one of mine, as well.
