How long do the batteries normal last on heavy usage?

It depends a lot on the project...7" screws into landscape timbers take it down a lot faster than 2" screws into decking. I also have an 18 volt Ryobi with Ni-cad batteries that I use and would say that, under most situations, the Hitachi 12 volt lith. does as much work as the Ryobi on a battery charge,,,sometimes it even lasts longer. I always have a second battery charges before I start any big projects.

I have this set, two chargers and 4 batteries. I can say I beat the crap out of these for the last 6 years doing home projects, subjected them to things I probably shouldn't have, and they're still going strong. "Heavy usage" is difficult to judge, but I'd say I'd could kill a battery in an hour with my heavy usage, maybe less if I really tried. I just leave a battery on the charger and swap them whenever I need to. I'll add that for my usage, battery life has never been an issue (but if I'm going up on the roof I do bring a spare battery). However, I wouldn't recommend them for a pro.

You'll need to define heavy usage. However, I have personally drilled 18 holes in RCC walls (to put up grills), before the battery died on me.Also, there are 2 batteries in the set, so double the fun.I've been using this kit for 3 years, and never got into a situation where I was left without the battery juice. The charging only takes a couple of hours.

I use mine a lot. What I have seen is the more I use them the better the battery seems to hold up. I never have to wait on a battery

I personally do not knwo as I used them for a teaching aid in a project but depending on what batteries you use they can last anywhere from 24-48 hours continuous (LEDs on). The consumption on it in standby mode is very little (~70 micro Ah) so depending on if it is placed in a high volume traffic area or not will also determine how fast the batteries deplete. The consumption when it is on and lite is ~70 mAh.

Bought mine last fall & batteries are still going strong. Don't use it every day but it is over 6 months. Bought it for my mom & we both love it!

I have mine set to power - saving mode and I can get three and half days of normal use. An average of 5hrs a daily.

I've been using mine off and on for a couple of months now, daily as it is. And I haven't replaced the batteries yet, I think it takes triple a though! Just use it and see for yourself. I wouldn't use it for hours at a time, my main usage of it is minutes here and there!! Hope this helps ya!!!

Wel we don't run the lights all the time so I only know that I have only changed the batteries once so far. We run them when we have guests over. It appears that they last pretty long though.

I do not have an exact time that the batteries last. I can tell you that I've used it numerous times and haven't really had any issues with battery life.

I've had mine about 4 years and am still using them. they seem to not hold charges as long. And I am thinking about replacing them. I use mine a lot as I have 3 appliances, 2 saws and a weed trimmer. I keep them plugged in all week and use them pretty heavy most weekends.

I am going to say probably 4-5 hours on average if they get a good charge during the day. I now need to replace the battery in one of them, but I have had them for about 4 months. The others I have are still going strong.

I does last for a long time....I bought mine in Feb. and it is still going strong...normally they are supposed to last 50,000 hours and I am still counting.

Depends on how much you use it. I use it every weekend and the batteries last for about three weekends of steady use.

It depends on if you're using them continuously. I would say you can get about 8-10 hours (though this varies). You can extend the life by removing the batteries when you don't need to use them. You can also buy replacement batteries, but they tend to be expensive so I would recommend buying new ones.

Usually around 6-8 hours. I've never had the battery die on a full days use.

Generally lasts about 20-30 minutes of continuous use with fresh alkaline batteries. If you switch it off when not in use, you can get as much as 40 minutes out of it total.

I use mine almost every day, and haven't changed battery yet. Bought mine eight or nine months ago. :-)

the battery life lasts approx 4-8 hours...sometimes longer if not used continuously.

I''ve had mine for 5 months now. Batteries still indicating more than 50%. I don't think battery life will be an issue.
