How long do the batteries function well? I've been burnt by wimpy batteries. How much are replacement batteries?

The new 4.0AH batteries give you a true 45 minute run time of non stop usage. We tested these units out before we brought them in from our vendor to sell. Oregon has done a terrific job on this new battery. Replacement batteries of the 4.0AH will cost $199.00. Hope that helps.

Totally disagree with other poster. I've had these installed for months and I've never gotten more than a week out of a set of 18 AA batteries. Has nothing to do with usage. The issue is the Wi-Fi receivers are powered at all times waiting for a command from the controller. This kills batteries far too quickly. With new batteries, the system is wonderful, but that lasts only several days to a week or so. I no longer use them and will replace with wall-powered units as part of kitchen renovation. By the way, if you have to try these, get them from a warehouse club for about half the price asked here, and use them in time to return them for a refund when you see how short a time the batteries last.

Uncertain. A colleague of mine received two batteries and (knock on wood) they are still working fine. For now ... I have placed this in my lessons-learned folder labeled, "you get what you pay for". +++ Am in the process of returning them.

These Batteries will last a lot longer than 7hrs. when you get a good one, mine is still working very well. I bought mine a few years ago! I recommend getting them to replace yours! One question,How long did you charge your battery up before using? That might be an issue!

Dennis the simple answer to your question is these batteries are crap-however the seller is fast with their refunds in an attempt to cover their tracks- you get what you pay for there are decent replacement btteries. - just not from Onlite

Beware!! The batteries are only warranted for 30 days!! These are probably used. I got 60 days before they gave up. Neato doesn't tell you that the batteries aren't covered for 90 days until they die!

I have had no problem with mine they still work or recharge well and hold a charge when not in use. I really haven't recharged them enough to know how long "Normal" would be.

Don't bother. The batteries last a week. Maybe. Without ever turning them on. Have tried several batteries and even exchanging. I would turn them on once for 5 minutes, turn it off. Come back a few days later and they don't turn on and need new batteries.

Well... I can't say how many charges they'll take, but the first two charges of mine have lasted over 20 hours (I think the first charge was around 30 actually) so I don't think you'll have to worry about them dying on you anytime soon... at least I hope not. If you're really worried, just go and get the older glasses that use watch/button batteries... that's the safest bet, I guess.

We have never had issues with the batteries in the past and these have worked well. I can't even give a time frame on the batteries for these but if you shop on Ebay or Amazon you can usually find better prices. Sorry no battery problems so far.

Mine are still on the original batteries and I've used them through 3 dinner parties. They have run approximately 12 hours for me and there is still light. They are led lights so they pull very little off the batteries.

After about a year the batteries were still working fine. That said, I'm not sure how long they'll actually last because, for SAFETY SAKE, it is recommended you replace batteries ONCE A YEAR regardless if they're still working or not. I change mine every fall around Daylight Savings Time. (I keep the partially used up batteries, in a marked "Used" baggie, for toys or other odd uses; but never for smoke alarms!) Hope this helps.

These batteries will work but they arent the best. I have already burned through them and they aren't even a year old.

mine have worked very well,but they don't seem to last as long as more expensive batteries,so i keep extras on hand.

Stop buying crap batteries. I have one and they have lasted over 5 years. I change them yearly now that I started to use my fireplace.

I don't leave them on all the time but at least 20 to 30 hrs prob more. They are a common size flat battery easy to replace and has like 3 settings of flashing and one solid. My batteries havent ran out yet.

Hi W.J.Two thoughts here. First, I'm not happy with the performance of the battery's life -- seem to work OK for low power items (i.e. wireless mouse), but fall way short of the mark for higher demand items (flashlight) -- I'd guess 10 to 15% of an Alkaline battery life. That said, and in all fairness, it appears there were a number of 'knock-offs' introduced into the selling stream. I'm not sure if mine were part of the counterfit lot.The customer service group at Eneloop aren't the easiest to work with either. I invested about $350 in batteries, cases, charger, sleeves. I wish I could get my money back and move on.Sorry to share my disappointing experience. I hope yours is better. Hi W.J.Two thoughts here.
