What batteries do these need?

I have an old model that I purchased in 2007 and it still works with 4 AA batteries. I use dollar store alkaline batteries and they work just fine. The base you can plug in or use an optional 9 volt battery in case of blackouts.

It uses 4 AA Alkaline batteries, they last about 6 months more or less depending on how often it is activated. Alternatively you can use Lithium AA batteries but it's not necessary. This unit is just the outside transmitter, it requires an additional inside receiver (sold separately) which uses an AC wall transformer and needs a 9v battery for back up power.

It takes 4 AA Alkaline batteries. (Lithium batteries recommended for colder environments.)

This particular one needs 4 AA batteries (not included). My older ones use 2 AA batteries. If you set these sensors outside, such as by your front door (one good use is to know when deliveries are made such as from UPS & FedEx and the like since they often don't ring your doorbell) and it gets below freezing, use lithium batteries - expensive but they work all the time and last quite a while.

Double A work great. I bought Lithium AA's due to fact the transmitters are across street from my house, in a building w no power; and more durable in cold weather.

AA batteries. Depending how many times the alarm goes off, they should last approximately 6 months.

They use two double a batteries. They only last about 6 months each but they work great until they stop. I am on my second order!

Not sure, batteries are already included. I believe they are rechargeable batteries.

Hi. The replacement batteres are Li-ion rechargeable 18650. These are 3.6v, should be 3000mA.These are readily available with a charger through Amazon- I bought several sets and have had good luck.

I know you need 1 9volt and the rest are AA Batteries but I'm not sure how many of the AA you need!

I'm sorry but I don't know what kind of batteries. I purchased this item, but it did not work properly and returned it, good luck on finding your answer.

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.

These take AA batteries. I own a few of them, and I use rechargeable AA. They work great on either alkalines or rechargeables.

They run on batteries. I had have them for more than 6 months and still on the original batteries

If memory serves, they are LR44. The one I received came with the batteries.

Regular batteries, but don't waste the batteries. Not a good product. Poor performance

If I recall correctly they take AA batteries. The battery life would depend on the batteries, I guess. We don't use them for very long at a time so I am sorry I cannot be of much help.

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!!

I recommend using the Surefire brand CR123 batteries. They are quite reasonably priced!http://www.amazon.com/gp/product/B000UX93OQ

AA rechargeable NiCad batteries. These should be included with the lamp initially. You will need to replace about every two (2) years for best performance.

Most likely a small flat round battery. They come with batteries and they last long.
