How long are rechargeable batteries normally last before you see it not holding charge very long? My last one was appx. 4-5 yrs, w/light use?

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

I have had them last 5 years with just moderate use per day and up to 3 years with heavy use recharging twice daily..I also do rejuvenate them after that time to get an extra year out of them before I buy new

Odd question - Do you understand what a rechargeable battery is? The battery doesn't get charged from the factory (like an alkaline cell) and then run for 3-5 years; a rechargeable is being recharged constantly during its working life. Even rechargeable batteries have a lifespan before they fail.

? i use it to there is no charge left in it , then recharge , that takes about 5 hrs to charge , thats why i bought 2 of them , they can run the unit for about an hr , as with all my battery operated tools , i let the battery run out , then completely recharge them , you may have a defective battery , if you get a new 1 , dont try using it , till its completly charged , 5 hours , then use every bit of power left on it before recharging , battery's have memories

Several months like - for me anyway about 5-6 months and they are still working. Have you ever considered buying rechargeable AA batteries?

I believe about 10 to 12 weeks. I like the battery opperated one better than the rechargable ( my adult children have those) and they lose their charge quickly and often only when you start to notice an odor is when you see its not working.

Not a expert but my experience w/ similar type emergency lighting batteries is 2-4 yrs. They actually would last longer if receiving a discharge/charge every 3-6 months. Probably why people report these go bad after 3-4 yrs because they rarely get discharged/charged. If you do buy a spare keep it in a cool place and that will help the shelf life.

From what I am seeing online, you can keep it plugged in to last longer (charge it). It lasts for about 15 minutes when fully charged and lasts for a long, long time (no real time table for the battery though). Can be a year, can be 5 years depending on usage.

I've only had it for a week, so no battey problems yet. It lasts my whole 10-hour work day on a full charge. There aren't any instructions included abot replacing the battery, but it looks like someone else responded and said it IS user-replaceable. Li-ion should last for years, but good battery maintenance will help extend the life. For at least the first 10 cycles, I charge it fully, then drain it completely. Don't recharge when it drops to 80%, 60%, etc. The performance doesn't suffer at all even when it is almost dead. That should help you get the most life and best performance.

I do not use rechargeable batteries, I use the regular alkaline type and get my 4-6 hours that I need out of them each time. I replace the batteries on the next gig in order to assure no surprises midway.

Mine is over a year old and still going strong. I charge it for a half day or so and use it off and on until it starts to loose power ...then back on the chager for abiut another day. Most rechargble tools should not be pluged up all the time and it is best to let the batteries drain to low before recharging.

mine lasted about 4 months, then stopped recharging....I threw it in the dumpster

I have used many rechargeable devices over the years and, yes, with light use, it should hold its charge for a few years as other similar hand vacuums do. It seems that this is a defect and that Amazon should work with the manufacturer to rectify the situation. If they do not, I will certainly try not to buy any more Black & Decker products.

Hi, ours is fairly new so I haven't let it sit real long, but it is holding well. It says to recharge after each use though. When we first charged it was real hard to tell how fully it was charged. There is an LED display, but not real helpful.

Mine is near 3 years old. Battery life is certainly shortened now (probably 10-12 minutes run time) but zero complaints about its performance. Gets used a few minutes every few days. I have been guilty of leaving it on charge a few days over the years. Certainly been a good value so far. Will likely built my own battery for it when the run time is unusable.

I haven't tried to measure how long it holds a charge, but, like the others who have responded, I know it is at least a few weeks. Also like others, the blue light on mine goes off after a little while. Do you have the switch in the off position?

For me, so far, it has been lasting just about 2-3 hours on a full charge. Almost 1 year of usage so I do keep it plugged in when not in use and definitely overnight.

I had fantastic luck with regular double A batteries as well. Generally, they would last for maybe about 8 hours of life, and I always got accurate battery life readouts, and was always able to replace them when they got low without any issues.
