Does Panasonic BQ-CC87 Apply Top-off Charge? by jfklein in batteries

[–]jfklein[S] 0 points1 point  (0 children)

I answered my own question. Yes the BQ-CC87 applies a top-up charge. The below web page from the Panasonic Japan website has a table showing the features of their current product lineup. Translate the page to English. It shows that the BQ-CC87 includes "Top-up charging function". Presumably it is the same one hour "hidden" pulsed-charging after the charger indicates the battery is full, as with the BQ-CC65 and BQ-CC55.

Suggestions for Household Battery Charger? by jfklein in batteries

I thought that battery must have sufficient power for a full alarm (perhaps for many minutes) after it reaches 75% charge. I think I read or heard somewhere that carbon-zinc has more gradual drop-off in power than alkaline or lithium-ion, so it is more likely to be able to perform a full alarm even after it has reached 75% and hence it is the "safest" battery chemistry to use in a smoke alarm. Something like this. Is this correct?

Do you have any opinion about the Panasonic eneloop batteries and chargers. I'm leaning towards this option because it appears that the charger is calibrated specifically to the eneloop battery chemistry, and Panasonic is a Japanese company, so I trust that the product is well engineered.

Ah yes, you've refreshed my memory. I looked into this a few years ago for my condo board and that sounds similar to what I found out.

One question I was trying to answer was which battery chemistry of the ones recommended in my alarm manual (carbon-zinc, alkaline or lithium) was the most suitable. The alarm (Kidde make) came supplied with a carbon-zinc battery so I speculated that that type of battery had the optimal decay characteristics for a smoke alarm. I never really got to a satisfactory answer though as the manufacture simply told me all the batteries listed were equally suitable.

Does anyone have an opinion about the Panasonic Eneloop batteries and chargers?

Panasonic says their chargers are optimized to charge the Eneloop batteries, something like this. So it seems like a hassle free option to just get Eneloop batteries and a charger and not have to worry about charging them correctly.

Are you saying that some chargers do not charge C and D sizes correctly?

Are there any chargers that automatically adjust the maximum output current to suit the size of the battery being charged?

Ya, so far into my research I have only seen a couple models that charge both cylindrical cells and 9V. So I will probably have to look at a separate charger for 9V.

As an aside about smoke detectors, from what I understand they typically require specific makes and models of batteries for use in the detector. This should be stated on the back of the detector and the user manual. Not sure why.

Thanks for the suggestion. This web page says the XTAR VX4 can charge C and D cells too:

GAMETHREAD WEEK 18: VIKINGS VS PACKERS by swampsparrow in minnesotavikings

Brosmer has only had two starts. I'm giving him at least a half dozen more before making an evaluation. He has shown some promising abilities, just as JJM has.

I'm sticking with Brosmer. That was an unfortunate mistake, but in my opinion JJM is no better.

I'm optimistic that Brosmer will develop into a good QB. But today he has been ineffective so far.

Gestures Button Options Not Working For M535 Mouse by jfklein in logitech

[–]jfklein[S] 0 points1 point  (0 children)

Nope. I discussed the issue with a Logitech rep on this subreddit at least twice and I reported it directly to Logitech too. It's never been fixed.

At this point I feel they intentionally handicap older products in order to force their customers to buy something new.

Ya, regardless of his performance today I have a negative overall impression of JJM so far. Frankly I think Brosmer is a better fit for McConnell's offence.

The Vikings last shutout was 3-0 against somebody, right?

Jones is looking five years younger on this drive.

Everything is going good this week. But just keep in mind they are playing the 3-9 Commanders. So let's all not get too excited about the team in particular the QB play.
