Do these chargers have a shelf life?

I have been using the same box for years and not once have had a dud. I do not think they have a shelf life.

I'm not sure about that. I've had some for over a year and they were just fine.

Its a solid state battery, and the shelf life is at least one year in dry storage.Manufacturer recommends on trickle charger when not in use, however.

Yes. I never had any problems with them and the expiration date is about a year in the future.

Not yet. I have 3 and so far so good. I've only used them once each, but I did check them pretty often during use. I don't think I'd recommend going off and leaving them charging. Probably good idea to monitor them until you get a feeling as to safe or not.

I don't know. I use them within a week of charging. Some that have set for 6 months still have a bit of charge to last at least an hour probably, but I didn't pay attention.

They are dated with a time stamp saying how long they will retain the full charge they were shipped with. Upon inspection they needed charging when I received them....

Not sure about the shelf life, but I've had mine up to two years if stored in a cool dry place .. maybe even longer, asthey are sealed in plastic....

I don't think there is a shelf life. I keep these in my garage in three-digit weather in the summer (Sacramento) and have not had any issues with spoiling or degradation due to the heat. There are a few left in the box and they have been through one summer and one winter so far with no issues.

I had mine on a shelf for over a month and they were still fine. I would imagine they have a shelf life of at least 6 months or longer.

My experience is that these batteries last about 2 years in use. I don't know about shelf life but I wouldn't take the chance on it.

Yes, just be very careful that you put them in correctly. Otherwise, any remaining charge in the battery will melt the charger.

Yes, there is a shelf life. The box I bought in May, 2013 has an expiration date of 02/2017. Since each tablet is foil wrapped, they should last that long.

As I recall, the shelf life is one or more years. I was pleased with the inks and will purchase more when it is time. I'm on my 9th printer since my first computer in 1987. I have purchased after market inks before and these are as good as any I've ever had. You can't tell the difference when oprinting.

No problems so far; mine are 7 mos old. I noticed that Amazon sells a replacement charger, which I don't recall having seen being sold for other units. Maybe these units have short lived chargers. Only $10 with free shipping. Considering the cost of the units compared to other brands, it is still a bargain.WALL CHARGER WITH USB DUAL CHARGING CABLE FOR ALL MODELS OF AETERTEK DOG TRAINING SYSTEMS/FENCE SYSTEM,GROOVYPETS GP001B,GP002B,MAGIC E COLLAR MEC-1

Yes, I'm using them in mine for about 3 months now. They seem to be holding a good charge. Time will tell if they continue to perform well.

I am not sure the shelf life all raped up I would not trust to be more then 6 months. I know they don't last longh after you install them even if you don't print anyting.
