Trouble reading details ?

Good deal OP, but do I really need to charge 5x 9V batteries at the same time ?

Guess your right. thanks

Or the more practical 2-slot charger with Li-on https://www.amazon.ca/dp/B01486761C/

I would buy if it was free shipping. Hope that this will still be live on boxing day when I can find other stuff to buy for free shipping.

I really want to use for smoke alarms in the house as am tired for having to buy 9V batteries each time weak signal beeps ọn However have been told in other threads not to use rechargeable batteries for smoke/fire alarms, however here the description says these batteries are good for such. What gives?

I would not use rechargeable in smoke detectors. It may not trigger the low battery warning sound. It is a safety issue and regular 9v is not expensive anyway. You can also get those 10 Year battery life smoke detectors.

Just a word of caution - while I have not used any of the chargers or batteries listed above, I have not had good experiences with EBL products (18650 Li-Ion & AA/AAA fast battery charger, both of which I had to return, and are currently no longer available). I'm not saying these are not good deals, but please test them properly & make sure they work as advertised.

Thanks. I will heed your advice.

Just was curious as they advertised: "BL 9V Ni-MH Precharged Batteries: Specially designed for household devices like smoke alarms,..." what is so specially designed for? False marketing I guess?

These may have high self-discharge rate, so they will discharge much faster than alkalines, not because smoke alarms will eat them but simply because of their nature.

According to this Web site, the EBL NIMH is 8.4 Volts.

"9V" is the physical size/shape, not the actual voltage. An alkaline 9V is really 9 volts, but a rechargeable "9V" battery is initially 9.6V, 8.4V, 7.4V, or 7.2V, depending on the model in question."

I would not use rechargeable in a smoke detector.

Some municipal bylaws (like in Montreal) now mandate a 10-year lithium battery equipped smoke detector.

This is the case with NiMH batteries in general. Each cell has a nominal voltage of 1.2VDC when fully charged. This is in contrast with 1.5VDC for alkaline and Li-ion batteries. The difference doesn't matter in most applications. But in some cases it's simply not enough to reliably power the device.

So as you point out in the case of "9V" NiMH:
9.6 = 1.2 x 8 cells
8.4 = 1.2 x 7 cells
7.2 = 1.2 x 6 cells

Some municipal bylaws (like in Montreal) now mandate a 10-year lithium battery equipped smoke detector.

Smoke and CO detectors have a service life of 10 years no matter how they're powered. After that they have to be replaced. So one benefit of a 10-yr Li-ion detector is that when the battery expires you automatically replace the whole unit, including the detector(s).

AAA don't seem to be on sale. Needed for new land line phones. Don't want to wait too long, so I guess I'm stuck with Duracell or Energizer from in town sources. Thanks though...

Yeah, that's why I went through all the bundles, tried to find AAA bundle with a charger, but had no luck.
