notification of dangerous product from eBay after a while
So, eBay spams with messages after your purchase of button cell batteries?
Is this specific to this seller as I have seen such notifications for past button cell battery purchases?
Same.
I believe there are plenty of fakes around…
I bought 20x same model from the same seller and it worked a lot better than my genuine Panasonic on Tuya Zigbee sensors. Though it doesn't work as well on Xiaomi BT thermometers. YMMV but this is genuine stuff.
Yep. You can test them by sacrificing one with a 1k resistor across it's terminals for a ~3mA draw. Takes days or weeks to complete, but it's informative. Some of the fakes were barely a quarter of the capacity of the genuine articles
Good price on eBay from a reputable seller. Though it used to be $25 for 20x delivered on their own website, with (resonable) markup on their eBay store. But it seems now only 100x box in bulk is selling on their own website now.
eBay Plus members may have a $20 off for $100+ voucher - use it against https://www.ebay.com.au/itm/296499444294 would bring price down to $114.95, or just buy 10x of this listing for $114.50. Not sure how the seller would send you, whether 20x5 separately or a box of 100x LOL
(100x button cells for 7 year shelf life is not bad - especially if your home is flooded with Zigbee sensors)
what is the packaging on these look like?
thanks, might as well
Anyone know if the $8.99 for 10 packs of generic ones at Supercheap Auto any good?
They don't last long according to previous comment.
Which is the reason I went to look for better alternative even if paying slightly more.
Good to know, thanks!
At that price they are actually expensive. Bought them several times for $2 and less. Their voltages vary widely, but for non important items they are OK. For airtags i use other brands. Including these
Out of stock
There are a few links for the same product with same price as each listing come in and out of stock.
I've added additional links
Thanks, need some of these!
Just in time when my car key have started showing signs of weak battery.
Anyone remember the early viral meme about AA batteries just being a big stack of button cell batteries with a wrapper around them? Had me fooled, back in the day.
I find that the Kmart 2032 batteries work way better than most that I purchase on eBay, including many big names like Sony or Maxell, suspected most of these online ones are fake
yes….
Do these have the bitter coating?
Waiting for JV to bite….
These are my go to brand and seller.
I stress test button batteries with a 30mA pulse and <1mA constant load to see what will hold up. The voltage during the pulse drops fast for poor quality cells, but these hold up right through the discharge so you can use most of its capacity.
Only these and the anko 4 for $5 last, everything else I've tested including Energiser and Duracell fade quickly at high pulses
Does being able to hold constant load mean it is not suitable for low draw devices like key fob or kitchen scale? Things that are infrequently used.
No, good lithium batteries are supposed to maintain voltage until close to 0 capacity left. It is just a sign of poor quality if they do not.
Low draw devices use a low amount of current, but they expect to be fed the voltage on the label of the battery
The small constant load is so I can discharge it completely within a couple of weeks, minimising the data I'm logging. It doesn't mean it's not suitable, they all should have good shelf life but the ones that hold good voltage during the pulse will be able to use more of the battery capacity if the load requires it. A key fob is a fairly mild pulse load, kitchen scales should be a constant drain during use, for very low drain devices there may be benefit using a battery that prioritises capacity over power output, though the highest capacity I've found is only marginally better than anko and Maxwell anyway
Just a warning that you tend to get a notification of dangerous product from eBay after a while
