So you have to change the batteries after 45 minutes of use? Wow. Is that actual use or is there a standby mode?

As others have said, no standby, yes it's more like 30 minutes, and I'd recommend rechargeable batteries. What I use it for, it's perfect. (Inside automotive, to seal heat shrink tubing better, making my own "double heat shrink" which is just adhesive inside the heat shrink tubing.) If you use NiMH batteries be careful you don't let them totally drain down all the way, it really damages them to do that.

There is not a standby mode. The unit uses the battery to sustain the heat. This unit is ideal for doing jobs that don't have easy access to an electrical outlet. If you do a lot of long sessions a corded glue gun would probably serve you better. You could also use Ni-MH rechargeable batteries instead of replacing with standard batteries every time they die.

no, this is not a standby mode, you don't need to change the batteries after 45 minutes use, but you could use the rechargeable batteries instead of replacing with standard batteries.

No, it does not have a standby mode. I have not been able to heat it up enough to really use it. I'm going to try better batteries and see if that helps.

I believe the timer is only for 45 minutes. The other choice is to have it in until you turn it off or the battery dies. It is fantastic and I love the size but we do replace the batteries often.

I use mine about once a month and have not had to change the batteries yet. I have them in for the past 4 months. Great unit!!!!!

My $15 version is sealed also. Even with the display on continuously, the estimated battery life is 4 to 5 years. I plan to simply buy a new, improved version when that happens. There may be a more expensive version with a replaceable battery.

I have only had mine for a few months and never turn it off. My husband has had one for over 2 years, never turns it off, and has never needed to replace the batteries. Supposedly they have a battery life of up to 36 months. Hope this helps.

I have the same problem with the batteries not lasting. I did an informal test with new alkaline batteries and after 2 hours 7 minutes of solid on it goes to the power saving setting. If you turn it off and back on it will go on high for about 1 second then goes back to the power saving mode. Not happy. This isn't what I expected from Mag-Lite and it will probably be my last.

I'm not sure about the battery life. But I haven't changed battery yet since I bought mine. Just be sure to turn it off after you use it.

Do not leave it plugged in! I did and my battery is now dead. It turns out to be VERY expensive to change the battery b/c you must send it back to the manufacturer to do so. There are some good tips here on preserving the battery life that I really wish I had known beforehand. I'm currently trying to decide if it is worthwhile to replace the battery or not.http://1866uselady.com/show.php/en/online_store_2

Same as the other two responses, I have never used it long enough at one time to find out. I rarely have to change batteries though.

If there's a way to change the battery, I couldn't find it. Mine died after about 4 months. I like the unit, so bought a new one but if its battery dies as soon I'll have to try another product.

Not real sure about just standby time, because I'm either constantly playing real racing 3 when home after work and weekends or listening to radio and stuff when I'm at work. As far as usage goes though, they have been pretty impressive compared to original battery and to what i actually expected. I expected a much faster discharge, but both anker batteries stand up to my original

Short answer is yes. They have a stand by mode, but shut off fully after a few minutes. In stand by, you can use the remote to power on or back into stand-by. I wish they would stay in stand-by, but it is probably designed to save batteries when not plugged in. I usually just leave them powered on and turn down the volume.

About 2 hours with activity, stand by is several hours. But after a few weeks of use, battery life goes under 1 hour. I plugged it in for 3 hours, and only 1/3 of it was charged. Really awful battery life.

Though I manually turn mine off to make the battery last as long as possible; the manual indicates it turns itself off after 10-15 minutes of inactivity. I consider that to be both good and bad. It's good if you're forgetful - it's bad if you want to closely monitor something longer than some preset time limit.

Is the "battery" in the 4460 maybe a capacitor? Can anybody who has one confirm if there is a replaceable battery? Nowhere in the maual does it tell you how or when to replace the battery. My guess is that there is a capacitor. If it had a battery, the display would likely just stay on when it was unplugged. Seems like a silly detail, but I just hate the idea of having a battery that will likely leak if left to sit a while in a drawer.

It maybe gives me 90 minutes to two hours of standard use, which includes filming of course, standby, occasional zooming, etc. That is just an estimate, and I have not actually timed it. But either way it is a lot longer that what the included battery offers.

Hey Derrick... I charged it when I received it on April 30. I use it on average 2-3 hours per evening. I use the back light function every 30 minutes or so and the unit is in standby during the 2-3 hours of use. I turn the unit off each evening. I have not yet had to charge the battery.
