We have had ours at least ten years - one charger, two units - my unit just died and I am getting another set to share with my daughter - two units, two chargers. The batter in my husband's unit is fine.

We have never had issues with the batteries in the past and these have worked well. I can't even give a time frame on the batteries for these but if you shop on Ebay or Amazon you can usually find better prices. Sorry no battery problems so far.

Our first Philips Sonicare lasted 7 years before it would no longer hold a charge. We thought it was worth the money and bought a second set. We really like them and will continue to buy them unless something much better is offered. Hopes this helps

my first set went on for about 7 years, new one lasted only year and half. Cannot find itemized receipt so warranty does not cover.

Hi, the last one I had lasted over 10 years but I suspect the newer ones won't go that distance.

With Sonicare, the eSeries (screw-on brush) lasts much longer. You don't have to worry about the skinny press-on brush models battery life because the seal around the skinny little shaft will go in 6-9 months and it'll stop working. Might not last that long if you're constantly taking the brush off and on the unit.

The Sonicare are a re-chargeable toothbrush. A full charge last about 1 week assuming 3 brushings a day. This kit" comes with 2 handles and TWO chargers - they are small enough to pack any time your are travelling for an extended amount of time. It's always a good thing to take along a battery operated bac-up toothbrush; but I take my Sonicare everywhere. Have not tried outside of the U.S.

Have only had mine a little over a year, and I don't use it daily. The batteries still seem as good as when new. They hold a charge even when I leave them unused for a week or two.

You cannot replace this battery, at least without some electronics trickery. I have purchased three of these headphones and used the first two heavily for three years. They finally started falling apart and the battery life started getting bad, but I would estimate I wore each unit 3,000-4,000 hours before they wore out. I highly recommend them. Some might feel discomfort at first (due to pressure) but they conform to the shape of your head after a while.

I buy these batteries for my husband who wears Oticon behind the ear hearing aids and they last for about 4 days, which is about the same as when we were buying the name brand. These are the only ones I buy now. But remember that it depends on the device you are using. Some drain batteries faster. For the price it is worth comparing them to the name brands.

It's actually a question of economics. I bought 24 dated MAR 2021 which leaves only 5 more years of guaranteed life. The box was shelf worn. I was a bit disappointed but I will keep them. They were approximately $2.00 cheaper than other vendors with the same batteries with 7 years of guaranteed life. It's your decision of which to purchase.

They last quite a while. I mainly use them for my son's wireless remote for his Xbox 360, he plays everyday, somedays he plays allday and on average we usually have to recharge them every 3-4 months. I found them to be better than an OEM battery we've had.

The previous answer is right. You insert a AA battery in them, and then use them like a D battery, but you have to buy the AA battery first, and I imagine that they don't last very long, since you are trying to use an AA battery to do a D battery's work. But, if you want a rechargeable replacement for a D battery, then this is your option.

I've had mixed luck with replacement batteries, and it's not necessarily a "get what you pay for" scenario. I'd say the "bad" replacement batteries I bought probably gave me an hour of actual run time, whereas I've had good replacement batteries give me at least 4 or 5 hours, maybe more. I mainly use it for less than 10 minutes at a time, so it's hard to judge the run time I get out of batteries. Either way, replacements are small enough and cheap enough to just keep a few on hand at all times.

I've tried cheap batteries and expensive batteries and there is a difference in this type of device. Niteize sells replacement batteries that seem to last about 6-8 weeks with a daily 15-30 minute walk (usage). With the cheap batteries I was experiencing two weeks and they would go dead. Bottom line, you get what you pay for. As another response stated,you simply pry the back plastic off to gain access to the batteries - each device requires two batteries.

I've had a couple of these and even when new I don't get more than an hour out of a charge. Currently it's about 30-45 minutes. I've never found the batteries to replace the original and my belief is they aren't replaceable. I just buy another WLB26B since they are relatively cheap and I like them because of the light output.

These batteries are made for performance, not duration. I use these in my dive lights and I expect about 3 hours out of 2 batteries. If you use these nightly for 10 minutes, a month would be about 5 hours of use. I would say they are giving you pretty good performance.

Honestly I am not sure. I did that with my first one and it lasted a little over a year. But the battery is reasonable in price so it is worth it to me. I use mine alot.

Actually, I would be happy if I could find a spare battery for $50 or so. But $150?! When I can buy another unit for the same price? Weird. I'm not seeing a lot of support from B&D; for these units, which is a shame since they seem well-designed otherwise.

In my experience, these last as long as the battery - barring accidental damage. The older models had a user replaceable battery - not too easy with these newer models. If you care properly for the Li-ion battery, it may last 3-4 years - or even longer, depending on use. Of course, YMMV

I assume your hearing aids were designe dto take these batteries. If so, the will last approx 22 on a charge to begin with deppending on how strong the aids are. Then as all recharable batteries do, they will start to last less and less. When they do not last all day you should look at replacing these. They generally will last about a year but I seen them last between 6 months and 18 months depending on the number of hours you use them a day.

If you take care of them they can last a long time. I found these to be much more comfortable and a better fit than what my dentist has made for me. Sixty some dollars versus $250.00 at dentist! I would definitely order these again and have given them to my children I liked them so much. Good luck!

It has been a while since I Have used these. I remember them having a good battery life. As long as they have a full charge it would last at lease one full length movie. They also come with all of the chargers, both car and wall outlet.
