How long a time dependant of use of course, but on average how long of service power do the batteries provide

For me about 3 days. I love this wheelchair. Easy to fold. Easy to use. Great tires. Does a very nice 360 degree turn. The best purchase I've ever made on amazon.Nancy O

I have been using it every day since March. It is easy for my husband yo put in the car for me as I have ALS and can not walk or talk. He charges it every night for me. I really don't know how long they will last. I would say about six hours or twelve miles. I like mine then what is out on the market today with medicare. This is mine, not theirs that i would have to rent. Hope this helps you.

It takes 8 hours for both batteries to be fully charged from empty to full. But most of the time you probably find some capacity remains in the battery, so it will take mostly less than 8 hours. Charge it every night before you sleep, and it should be fully charged when you get up. With full charge, it can run about 20KM which is about 12.5miles. (testing on flat surface running non-stop).

The batteries average life is 1 to 2 years. Usually after 6 months of use, it will start to give you less mileage per charge.

My batteries like these (I have a few) have lasted well over a year. Average with daily use has been a year and half and more.

Depends on the brand of batteries but I was energizer max and using it everyday they last a month or two

Secondary batteries are rated in charge cycles not years. How long they will last will depend on how often you charge them and to what degree they are discharged before charging.

Battery - guess it depends on how much you use it. Sorry I can't be more specific

I didn't do any scientific measurement. My opnion is therefore subjecive. It appears that these batteries do last. This key is to get them fresh. Batteries do lose power with time if you let them sit. Some lithium button batteries that I purchased on e-bay were two years old and lasted about a week in my guitar tuner, which is way too short. I blame it on the age of the batteries. Those 9 volt lithium batteries don't seem to have this issue. We'll see in a few years.

A very long time. I would say somewhere around 30 hours. The battery lasts forever though.

1. UPS run-time on battery varies greatly by how much load is connected to it, but an estimated run-time is displayed on front panel. 2. How long before batteries have to be replaced also varies greatly, but will likely be two years or more. The way I keep track of the battery's usable lifespan is timing how long it takes for the remaining charge to drop to 75% when powering a single 100W incandescent light bulb when the batteries are new and then about every six months thereafter. When the elapsed time to 75% drops to about half of what it was when batteries were new, new batteries need to be installed. 1.

My batteries are still good. I would imagine the life expectancy depends on whether the lamp is left on continuously or intermittently.

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 will check date on battery box and respond, the batteries are suppose to last ten years. My use of batteries are to power Fire and smoke detectors so I expect 120 months of performance.

Well we have had them for almost 2 weeks and one has never been turned off and is still going strong. We haven't used them as much as we thought though. So even though the batteries have not died with it being on I still wouldn't be able to tell you how long they last if you're using them consistently. Overall I would say they conserve the batteries well.

depends on the batteries you use... I guess. but mine last for about half a year

Hi Larry: In my experience, 4 -5 years is about average depending on the number of recharges. The large batteries for tools can be rebuilt by some stores specializing in that service, for half the cost of buying a brand new battery. Best Regards, Doug

Around 2 hours, the actual operation time will depend on how much electricity is required by the device and how you use it.

I still average about 2-3 hours on mine. I've had in the neighborhood of 15 months. Been a great battery.
