I used thinner or smaller wrong sized battery for the key fob

Mon Jun 04, 2018 5:17 pm

The manual says CR2025, I used thinner, thicker or smaller battery for the key fob, it worked. Anyone tried the "wrong" size yet?

There is a topic on this. Sizes CR2016 through CR2032 will work, although some people have trouble with the 2032 being too thick.

what about smaller in diameter? for example the 16mm diameter battery.

All you need is appropriate Pos/Neg contact since those batteries are the same voltage. They are NOT the same CAPACITY, and obviously not quite the same size. The smaller one will not last as long. If you 'stuff' a larger one into a smaller space, that may or may not work. If it does, it'll last longer.
2016 > 20mm diameter, 1.6mm thick
2032 > 20mm diameter, 3.2mm thick
That's how the sizing is determined.

How well that works depends entirely on the device you put it into. Some can be forgiving, others...not so much. I have a dive watch that has a VERY weird battery size. I put a smaller diameter but same thickness coin cell in it and it's been working fine for a loooong time.

a question, I know the capacity is specified by the mAh, but can you guarantee that a 2032 has higher capacity than a 2016?

maH is capacity. 2032 is a bigger 'bucket' than 2016. All things being equal, 2032 absolutely has more capacity.

Having said that.....there can be a LOT of different qualities of batteries. I use a lot of 2032. I try to get devices that use those rather than have a dozen different cell sizes for devices. So, I bought a bunch of cheap ones off eBay, like $0.25/cell. They were complete and utter crap lasting 2 weeks in devices that would go 6-12 months with a decent 2032.

Age, and brand DO make a difference here.
The drug store and hardware store are usually easy but expensive places to get decent batteries. You can often get exactly the same cells for 1/4 the cost with a bit of searching. I needed 1632 for a fob. Drug store = $3.95 for 1. Amazon = $5 for 5 of the same brand. Shelf life is pretty good. Date them, keep them cool, and store them. But if you haul them out 8 years from now you may be somewhat disappointed.

One decent cell beats a half dozen junk ones.

It should also be noted that Ebay and even amazon.com are known for having counterfeits for sale. This is one instance in which it's best to shop locally, so you can return them if crappy, and to lower the likelihood of counterfeits. I've had good luck with Dollar general: great prices and they seem to be the actual name brands.

yes, that $5 for 5 was what I got, it has been good.

Don't know how to spot the counterfeits. The cheap ones I got were pack of 5 and they were not name brand, so at least they were not pretending to be counterfeits for name brand. They lasted for a year, so not too bad.

Did you have concern of counterfeit for bad quality? or just you don't want to provide moral support for counterfeits?

there is no Dollar general near me. There are only Dollar Tree stores near by, but they don't have coin batteries.

Of course not. I can "build" a 2032 out of aluminum foil and peanut butter. It won't have ANY capacity.
I noticed you're still working with polymers.
