Overview: All Eneloop batteries 2005-2024

ChibiM,
Can you tell me anything good or bad about the eight bay Panasonic charger for envelops? Thanks.

Hey 264, no, I can't unfortunately. I haven't really looked into them.

I will soon run out of alkaline batteries and would like to replace them with nimh or the like. Some of the nimh will be used in a marine environment. The Coast Guard and others entities warn against using lithium rechargeables in this environment. A closed boat in the sun can generate a lot of heat. I’ve never measured it but it can get quite hot inside. Question: Are nimh batteries any more or less susceptible to heat than the usual lithium’s? Are nimh any different about excess heat than alkalines? I’m trying to make things as safe as possible on the boat. Most marine recommendations are to use alkalines, though I wish to get those out of my routine as much as possible. Thank you.

Oops.. didn't notice this question, but I think I answered it, maybe on Facebook?

Been out of touch of NiMH chargers for a while but looking to get a portable one. Anyone know if the BQ-CC87 is indeed a smart charger? The product page shows an image of the box stating quick charger.

The little light attachment looks cool. Anyone know where to buy one? I couldn’t find any info on it.

Edit: In the description it says “Charging times shown in the table are only indicative and can vary depending on temperature and battery status” so I guess it is smart?

I also found a photo of the back showing output as 0.5A x 4 (AA) and 0.25A x 4 (AAA). Anyone know if those currents apply regardless of the number of cells? e.g. if populated with only one AAA will it be charged at 0.25A?

Good question, as far as I know this is a smart charger

Thanks ChibiM. Done a bit more research and does look it is smart in that current is varied “depending on temperature and battery status”. I’ve edited my post above.

I don’t really need another charger but the powerbank feature is interesting and looking to put all the Tones I’ve accumulated to good use.

Good stuff!

I have it.

It is totally smart.

But with old batteries (high internal resistance) it has a bit of problem.

When using as charger… It reports them as “batteries should be replaced”.(but it charges them… Other chargers simply refuse to charge them)

When using as powerbank… The output current is not 1Amp… More likely 500-700mA.

If you want full 1Amp output, you must use young/new batteries with low internal resistance.

With my old eneloop XX( with a few cycles) it shows that behaviour.

With my white eneloop (with many cycles) it works like a charm. No yellow led indicating batteries should be replaced and full 1Amp output

Ah good to hear! Shame to hear about the output but I guess I could just keep some new cells with me if I need to use it as a powerbank.

Did you look into the little flashlight attachment?

Based on the charging time table, it looks like those current values apply if you charge all 4 cells simultaneously. If you only charge 1-2 cells, charging times are cut in half, which would indicate that current is doubled, so a single AAA cell would be charged using 0.5A current.

What flashlight attachment? I am not seeing anything on that page, unless I missed it or my ad blocker got it.

Are you referring to something like this?

Hmm ok, makes sense. I’ll take another look through the manual.

Here’s the attachment which I mentioned and also ChibiM posted a few pages back.

There’s probably nothing special about it and a 3rd party USB light would probably be just as good or even better.

Any way to get that led light attachment? Can be purchased separately?

EDIT: the led usb light attachment is included only in japan version. Eu version dont include

Correct, only available in Japan as far as I know. Still a fun attachment. I have one personally.

XTAR sell a little USB light as well, if it’s any use:

I don’t have one myself, though, so that’s all I know.

All aneloop and nihm type batteries are overrated and overhyped if you need run device with minumum 1.5 voltage battery. I’m really disappointed.

NiMH are nominal 1.2 V and they excel for their purpose.

How many devices out there require 1.5V minimum?

Most standard or alkaline batteries do not stay at 1.5V very long. For those applications, something like Tenavolts (1.5V Li-Ion) may be best.

Not many that I have personally, but my current clamp ( uni-t 210E) starts reporting wrong numbers when the cells are under ~1.45V, it’s really bad. My meteo station modules seems to have a high cut off, although not as bad.

I’m wary of the potential self discharge rate of a li-ion cell coupled with a voltage converter, but more importantly they are extremely expensive.
