When I bought these half of them didn't work, you can't change the batteries either. Even though they say you can. I would suggest going to a different seller to buy these. I've had some great ones, but not from this company.

I have had the system for about 5 years and haven't had the battery replaced. Usually 5-8 years depending on your particular situation.

I'm sorry I don't know. I haven't had to replace it. If you take it to a battery place they can tell you when they replace it.

The battery is replaceable, as per the instructions. The lithium battery should last about 5 to maybe 7 yrs, depending on amount of usage.

We have had six of these units in our home for over a year. We replaced all batteries after approximately one year. One unit is outside in the cold and heat and it's batteries lasted a year. The unit will give a little chime note every three or four minutes when the batteries need to be replaced.

I have no idea. It came with batteries and, despite how often it's been used, I don't think I've ever replaced them.

Not sure I understand your question. Are you asking what is the battery life i.e. when the battery needs to be replaced or when it needs to be recharged?

They typically last 6 months. It depends on how much you use it. I change mine every 9 months.

The battery usually last about 2 yrs. I would get it diectly from the seller, I did and the seller sent me a new one right away, but again that will depend on your seller. To remove and insert a new battery is very tricky, so it takes some tweaking. However, if you just bought the product, send it back for a new one. I'm very happy with my two.

It takes 1 regular replaceable AA battery. According to website it last for ~1yr. I have been using it daily for ~5 months or so, daily on the same battery. I am very pleased with it. Website also states that is 1000 dpi, if you care to know.

I have only had mine for a few months and never turn it off. My husband has had one for over 2 years, never turns it off, and has never needed to replace the batteries. Supposedly they have a battery life of up to 36 months. Hope this helps.

I do not have an exact time that the batteries last. I can tell you that I've used it numerous times and haven't really had any issues with battery life.

Greetings. Theoretically speaking, the batteries can last 100-120 hours. But it will also be affected by the battery type and usage. Thanks for your question.

It depends on how much you use it. Mine lasted a lot longer than 2 years. But I used it even after they become somewhat worn. The replacements were very easy to install and work great.

We regret to inform you the battery can not be replaced. Battery life will vary according to the frequency and length of use. If the battery is charged once every 2 weeks, the service life will be approximately 3 years.

I'm not entirely sure on that. But I've been using mine for a 3-4 months and haven't replace the batteries once. I use it on the go, so I turn mine off between uses, but I have forgotten to turn it off from time to time meaning it's on for 24 hours or so. Still have not needed new batteries though. Hope this information is useful.

It is a built in rechargeable battery. I do not know if it is replaceable but I suspect it will last quite a long time.
