The lithium batteries will last 2 years. You get two rechargeable batteries included and each battery holds 9 hours of usage per charge. They cost $24.99 sold separately.

Typically, battery can last up to 3 years, if kept on regular charge cycles. We recommend changing battery every two years.

You need new "rechargable batteries" I find I need to replace them about every 9-10 months, depending on how much they are turned on. We both watch TV about 6 hours a day and more on weekends. Ours screw up when they are not chargring in their unit.

One thing I have learned over the years is batteries last longer if you "exercise" them. I have 6 batteries for my Nikon. I have numbered them from 1-6 and I rotate using them in number sequence so that all my batteries are being used on a regular basis. In 10 years of digital shooting I have never had to replace a battery. I have bought new ones to add to my battery supply but never to replace a battery. You might want to try that strategy

battery is shot. The more you use it the less time it will last. Start looking on ebay or amazon for a replacement battery should cost 20-25 bucjs

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.

Like the others said I guess it's in the item specs. To be honest I've never had to replace them or anything. I have two of these and one has been going for a few years. Admittedly they only get used on occasion but the batteries have held up.

I don't know about the overall lifespan of the battery, but I do believe replacements are available or at least new pens are and I don't believe they cost much. It's like 15 dollars for a whole new pen. I've had mine for a year now, with daily usage reaching over 8 hours a day sometimes and I've gone as long as 2 months without ever charging it and still no sign of it slowing down.

I just had to replace our batteries. Radio Shack had the batteries- bought 3 for 12 dollars and change.

They are a bit expensive at $35 a pop, especially when you need ten or so, as I did. However, since this was the original equipment in the house, replacement was pretty easy. Although, the white power connector inside was sometimes difficult to disconnect. All that said, $350 for a replacement every ten years isn't all that bad. Make sure that the replacement date, which is stamped into the outer plastic is for around ten years from purchase.

Don´t know how long you´ve been using it for. If it is 1-2 yrs max with a minor-moderate usage I suggest you contact the manufacturer. I did it once at the beginning and they provided a great/quick service. If you´ve used it for several years then you have to understand that all batteries have a life. Maybe you´ve drained it a few times and it´s over now.

you know when to change it -- you will suddenly stop hearing, even with a good battery. frequency varies by the person. for me, it is almost the same frequency as the need for battery replacement -- once per week.

Contact the seller. The battery ought to last at least a couple years even in heavy use and the seller may send you a replacement or at least sell you one at a big discount. If not there are a number of good sources for batteries on amazon. Look for a 4-5 star product from a 90%+ seller if possible.

Well, I purchased mine about 6 months ago and they are good until June 2021 which means they are guaranteed for 9 years. Hope that helps! Also, I would recommend buying from Amazon rather than a local store because you will get fresher batteries (higher turnover rate).

Haven't had any problems with batteries. Spec sheet says to change once per year and that seems reasonable.

Yes, they will need replacing some time, but I would expect 2 or 3 years service first. My units came with good quality rechargeable batteries. You would notice the units running out of battery power after 10 or so minutes when out of their stand if they needed to be replaced.
