Does this tell me how much power is left in my battery, or how much wear or rather how much life? If not, what devices on amazon will?

this does not show battery life or life span i dont know what would if anything you may have to research

No is does not. Determining battery capacity is complex and there is a device that can do it but it it expensive. I will give you a link that will give a lot of battery information. http://batteryuniversity.com/index.php/learn/article/testing_deep_cycle_lead_acid_batteries

If you mean does it give you the level of the battery use....NO. But it works fine. Just keep an additional charged battery with you.

Don't really know what to tell you for sure. It is kind of a guessing game as what will work best for you. I am happy with my purchase, my battery was so weak that I had to stay hooked to electric (only had about 20 minutes on old battery) this one works just like a new one should. I don't think any of the batteries will do exactly what they say. (seems just like a guideline to me)

Not replacable? Bummer! My unit is 2-3 years old and battery life is down to about 10 hours or less now. I had no idea I was expected to throw away a perfectly well functioning device for lack of a battery. This seems crazy!

It claims to save 60% power, not sure what its comparing too and the amount of power it claims to use marked on the device is 9V === 0.6A. Hope this helps.

Which one of the two information always reset to zero for period of non-use? I hope only the top info. The lower accumulation meter should stay until the life of the battery. Was this the case?

Take a look at your power savings settings in the control panel. Manufacturers have gotten increasingly aggressive in such things to make claims about battery life.

Sorryfor late response...we cannof find on the battery any information that tells how much lithium is in each battery.

I have been using the device for two months only and very few times until it dies. The longer I have experiencie is almost 7 hours. I hope this is useful

I didn't use it long enough to know the battery life. As I said, it was inaccurate and I am sending it back

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

Jenny, I should also tell you that I purchased this device about 3 months ago and it just died on me. I am purchasing 2 more one to use and the other as a spare as I'm not sure about the life of the device.

I have no idea and amazon says you are not supposed to change the battery anyway.

Here is what my research found. I called Black and decker, they had no battery info on their screens for your unit. How ever, Black and decker did give me a # for a local service center. I called the service center and they also did not have any info other than the cost of the battery in question. But did state a new dust buster unit would be about the same cost as the new battery. my suggestion would be to see if there is a # on the original battery and match it up that way. I did relace the battery on my dust buster a while ago, not to dificult if you are a handy type of person. Hope all this info helps. Here is what my research found.

I'm not totally certain about the battery life. I left mine on using it here and there through the day and it well into the evening before I had to plug it in again. I also know that I left in sleep mode for over a week and it still had about 70% battery left it. It impressed me how long it would hold its battery power

The unit does not display that info. You could turn your vehicle on and see what it is. Given it only takes 3 hrs for a full charge on my Leaf that info is really superfluous.

When you're using AA batteries, and they run out...does it alert you with a message or icon?It must...but no one has mentioned in the reviews. Does it tell you LOW BATT at any point? Just don't want to be in middle of continuous shot and have the thing quit on me.Thanks,dix4@me.com
