How often do the batteries require replacement (relative to frequency/intensity of use)?

Don't know since I used it only once. Looks cheap, but works great. Sorry, I can't give the information you are seeking.

I have used it successfully for three months, approximately running 15 minutes a weekend and the D batteries are still running. Will change them out once a year for sure.

It depends on how high it has to lift. When i sat my gas can on the floor and pumped gas into my car it is about a two foot lift and the new batteries will pump 125 gallons before it would not pump any longer. When i put the gas can on a saw horse and it has no lift i was able to pump over 250 gallons before it would not pump any longer. One tip is spend the extra money on good batteries because it pumps faster and the batteries last a lot longer. I hope this helps.

I'd estimate they start declining after about twenty uses for me. I typically transfer 15 to 20 gallons at a time.

The batteries will have a longer life if you remove them when not in use. After a month of usage, I'm still using my original batteries.

Haven't changed them yet and been pumping fuel all summer, probably 40 gallons.

I have used this to empty the gas from a snow blower at the end of the season. It worked very well. When I was done, I took the batteries out to avoid leakage, so I cannot answer your question about battery life with repeated use.

Most of the time they last me all summer. The ones I put in when I got the pump are still in there so that is at least 3 months now. I hope that helped you.

ive yet to need to do that. ive had it almost 2 months. am quite pleased with how quick it is as well.

Good, I assume. I have been using it 8+ hours/ day for 5 dats a week and I've had it over a month now and haven't had to replace the battery yet.

A LONG time. It was years before I had to replace mine, but I don't use it every day. Maybe a couple times a week is all.

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.

Depends on the frequency of use. Have had mine for a year or two and still on the original battery. It's used a couple of times a day and every now and then about 20 times a day when the kids play with it.

This calculator has a dual power source: a photovoltaic cell used when there is sufficient light, and a battery for use when the light level is low. The battery is a LR44 (or equivalent) button cell. You have to remove the back of the case (seven philips-head screws) to get to the battery. The recommended replacement interval is every three years. This information is on pages 14 and 16 of the "User's Guide 2 (Additional Functions)" manual that comes with the calculator. By the way, I have had mine since July 2005 and I still use it regularly.

I suppose It depends on the amount of usage. But I have had mine since November 13. Used moderately but not heavily. A couple times a week for 30 min to 1 hour each time. I like them. If I could afford the $40 a piece ones I would get those over these any day. But for the money they do what I need them to so and so far no sign of wear.

I've never had to replace it and use it constantly (1+ year I think). It's one of the few things that I don't have to recharge nightly! ;-)

I have used mine 8-9 times each time was about 30-45 minutes. I have not replaced the batteries yet, but I do keep an extra set in my truck. I use lithium, due to the cold weather.

I have had mine for 3 months and have used it once or twice a day since then. I just changed the batteries in it today. So depending on you use I would say 2 to 3 months.

We regret to inform you the battery can not be replaced. Battery life will vary according to the frequency and length of use. If the battery is charged once every 2 weeks, the service life will be approximately 3 years.

Not very often. I can usually get through a couple long days of shooting before having to change them. I just use the basic Energizer or Duracell batteries too, nothing fancy. I've really enjoyed the mic, works great.

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

Mine about every 24 hours of use but that was with regular battery. Better ones would last longer.

I haven't timed them. I use it for about 10 or 15 minutes per day, and I have to change the batteries on average once a month.

Battery life is fine, I've only had to actually replace them one time since my purchase. Checked the mouse with new batteries to make sure the issues weren't battery related, but they persisted so I stuck the old batteries back inside every time. So one battery change after ~4.5 months of fairly heavy daily use.

I wish I could be specific about exact usage rates, but I use the light sporadically and do not keep track. I use Duracell Alkalines and so far have had no unusual usage issues, and I am still in fact on the original set of batteries.
