Has anyone tested if installed batteries can last for a year while being stored? Replacing a product that drained batteries in less than 6 months.

Obviously having this item with dead batteries is the same as not having them at all. What I did when I install fresh batteries is to take a short piece of cellophane tape folded in half along its length sticky sides together placing it between the tip of any battery and its respective contact. If you do this and stick the end out of the battery cover when they're needed you only have to pull the tape out and your still fresh batteries will be ready for work. My daughter used her set to help a stranded motorist recently with batteries over 2 years old but still fresh.

I disassembled an old unit that failed to charge after a year or so and removed the batteries. They would not charge with a "hobby" charger designed for electric RC cars and such. I then discovered that storing the unit in the charger when it is plugged in was overcharging the batteries. I have another unit about 4-5 years old that is still going strong. I charge the batteries overnight when they will no longer last a full brushing cycle. NiCad and NiMH batteries have a very limited life when charged to 100% capacity repeatedly.

Secondary batteries are rated in charge cycles not years. How long they will last will depend on how often you charge them and to what degree they are discharged before charging.

We have not changed our batteries yet. It is rather new...from a June-July purchase. We don't look for this to be a problem. Had another brand and it wasn't a problem. This brand and unit was rated higher than our ten-year-old wireless weather temp. I just don't expect to be disappointed with this brand....

Yea, I noticed the same thing. I got a unit in September and a month later in October I had to replace the battery. I thought that perhaps the original unit sat on the shelf for a while and that the battery was bad. Unfortunately the weather turned for the worse since October so I have not used it since and I do not know how this next battery is going to hold up.

It has been 6 months that we have had it. While it is not an item that is used everyday, we have had no problems with it. We still have the same batteries in it too!

I've had this for a little over two years. Battery "tests" OK, but it's hard to know how accurate that really is. In my experience all batteries test well until they suddenly stop working. I'm guessing I wouldn't get the time out of it now, that I would of gotten out of it two years ago. I will probably replace the battery in a year as preventative maintenance. I had purchased the Wayne branded battery they offer for this unit.

The expiration on my batteries is October 2016. I have had some new batteries that didn't work however which made me wonder how long that actually keep.

Thanks Phil. I was concerned that these batteries that are factory pre charged have not been on the shelf for months. There is a limit to shelf life on these batteries.

Hi Lyla, Sorry to hear that. I share a box with my dad and we go through a box (60pc) in about 5months time. We have never got a dud. I have bought the iCellTech from 2 different vendors though. They might let you send the duds back, not sure. Shelf life does make a battery go bad. As a matter of fact, the ones I own are supposed to be good till 2017. imho, they should last longer than what you have experienced.

I can speak to the battery life. I installed the base unit and one remote (outside) on 2012 Dec 2. I'd ordered lithium batteries for it (good for temperature extremes), but they hadn't arrived yet, so I loaded them up with some AA Duracell alkaline batteries I had. 472 days later, the main unit started losing contact with the remote, and I noticed its low battery indicator was on. The remote was still going strong. I replaced the alkaline batteries in both units with the lithium batteries that I'd ordered back in 2012. That works out to 15 months (over two winters and one summer) on just regular alkaline batteries. I'm expecting longer life from the lithiums.

I used to work for a battery company. If you keep them charged you should get 3-5 years out of them. Store them in your basement or somewhere cool. Do not freeze them ever

I wish I could answer your question. I only kept the machine for about a week. I did use it with the batteries for about 8 hours each night. As far as long term life of the batteries in the unit, I am not able to answer. Sorry, I am not much help.

Oh, thanks for clearing that up for me. But I'm kinda worried that they aren't replaceable. I've seen a few batteries die completely in a state where they aren't even rechargeable anymore. I hope these lithium batteries last if you can't replace them.

Batteries are not permanent storage devices. Due to their chemical properties, any battery discharges over time, even if not actively powering a device. If you want your batteries to last longer, take them out and keep than cool.

The rep at Cyberpower instructed me that the batteries have a typical shelf-life of about 3 years. I would presume that when your power-supplyied outlets stop functioning, that's when the battery has failed/died. Mine just happened to get hit by a power surge and hastened the process a little bit. I noticed this when the items plugged into the power-supplied outlets just stopped working, while items plugged into the regular surge-protected outlets continued to work (e.g., lamps, speakers, etc.)
