CR1620 discrepancy

[Keat63]

We sell coin cell batteries at work, so I purchased a pack of CR1620’s to replace the one in my plip.

It didn’t work.

Thinking maybe it could have been a duff cell, i tried another, that one didn’t work.

Tried a third, that didn’t work either. I obviously have a bad pack.

Refitted my original battery, and it worked, but lazily.

 

So the next day, i took from stock a different brand of CR1620.

The first one I tried, didn’t work,  what the heck !!!

With my voltmeter I measured it and the ones from the day previous, all 3.3v

 

In the end, it turned out to be the side contacts, the one which which sit alongside the cell (not the ones pressing down).

I bent them out a little, and now the new cells work.

Strange that the old cell must have been a micro millimeter wider than the new cells.

 

I’d replaced one in an MX5 plip for a lady at work about 3 weeks ago, she came to me this morning saying the battery had gone again.

Exact same issue. Bent out the side pins a tad and it worked a treat.

We had a member recently with dodgy battery connection issues, he/she had purchased new batteries and even a new button fob, couldn’t get a peep out of it, I wonder.
I think they were advised to twiddle the contacts, could be the issue you mention, who Knows/

I know I did my own fob, I bought a cheap replacement from ebay and had to fettle it a bit to make it work, new batteries etc. Still working ok more than 2 years on.

Sadly ,as with most coin cells you buy these days,most of them are junk.My Focus used to consume remote key batteries every 2- 3 months.I then switched to Duracell and haven’t had a problem since.Btw,for those who do or do not know,the battery number refers to the actual size of the battery.So a 1620 will be 16mm diameter by 2.0 mm deep.

Just replaced the remote battery on my Santa Fe, after 3 and a half years and 64k miles. It flashed a warning on the dash - " remote battery low" and gave a warning bong or two.
We were sat on Sainsburys car park so I trundled over to Timpsons, and after a quick call to the dealer to see how to open it -(remove the key blade and insert a screwdriver and twist) - 3 minutes and £9 later I was on my way, a quick test all OK.
Bit expensive, but I would have had to open it to check the battery type, then a 24 mile round trip to Halfords, we might have ended up stuck somewhere as the spare was in the safe at home!
I then spent 10 minutes searching for Mrs M in order to take over the trolley pushing duty!!

Just before reading this I tried to turn down the volume of our bedroom radio, using the remote. It wouldn’t. Having removed the battery to check the type, I wiped it with my fingers and put it back only to find the remote works perfectly.

As far as MX-5 key remotes are concerned, I’m glad that my “poverty spec” NB doesn’t actually have one. Only a key and no central locking. Less to go wrong on a twenty year old car… The only downside is that almost every time we go out, I have to keep reminding my wife to wait till I’ve unlocked the passenger door from the inside before she tries to rip the door handle off…!

I never knew that? Thought it was just some random set of numbers used by manufacturers? Every day is a school day

It’s like that with my wife, my daily driver has the key fob opening buttons. One press for drivers door, two presses opens everything else. I always forget and give one press, she’s there trying to wrench it open whem I forget to do the second press, grandkids the same and they are pulling with both hands though

Ah the fairer gentle other halves.  They are a lot tougher and stronger than they care to admit.

When we bought this house a couple of the doors were sticky, but they would open if given a little wiggle.  And I could only sort them one at a time because of work commitments.  There came a day soon after we’d moved in when I heard this frantic call from upstairs “The handle’s come off in my hand!!!”  She was trapped in the smallest room.  Until then this door had never stuck!  And I couldn’t open it from outside because the spindle was now on the floor inside.  It took a while to calm her down enough to look for the spindle and put it back in so I could turn the handle to open the door - which was not stuck at all, just on the catch.
