Side-by-Side Comparison - Sanyo/Eneloop Chargers

[Bones]

At long last ...

The Sanyo/Eneloop website in Singapore has made available a .pdf document which provides a detailed side-by-side feature comparision for most of the chargers/boosters Sanyo currently markets:

It specifically details which chargers have which charging controls, which have independent or paired charging channels and what their respective activity lights denote.

Very Nice, thanks for posting. I missed it if it was posted in the past!

Thanks, very nice chart.
Much appreciated

cool beans!
looks like there are a few other charger options to add to my travel pack :thumbsup:

I agree lebox97...

In fact, I'm somewhat impatiently awaiting the arrival of a shiny new KBC-E1S USB charger and mobile booster as we speak:

I think this was asked before, but not sure how to search for it.
Why are many of these chargers NiMH *ONLY*????

I had MQH01 which had a switch for NiCd. I gave it away and now my newer MQH03 doesn't have the switch and this charts shows NiMH alone.
Same for MQN06. But even simpler MQN06 has -dV detection which NiCd are supposed to have a prominent -dV. Also MQN06 is lower rate 300mA, ideal for NiCd AAs.

Anyway I tried a few old NiCd AAs in MQN06 and it terminated well before time limt, so it must have detected -dV.

So why would a NiMH charger having a decent -dV not be able to charge NiCd??? Use the slower MQN06 as an example.

The only reason I can think of is the time limit is configured for 2Ah Eneloops while most NiCd AAs are much lower capacities, less than half as much, so time limit is too long.

WAG:

Just spouting numbers from memory, without actually re-searching for them, I (think that I) remember reading the -dV range as ~3-5mV for NiMH and ~20-30mV for NiCD. So, my guess is that the 'NiMH Only' charger is too sensitive - i.e. it sees a ~3-5mV drop and terminates prematurely, when it needs to wait for a ~20-30mV drop.

I think that if the charger is "smart" (using -deltaV) and it has appropriately low current you can actually charge NiCds in it. When I was looking at charging ICs, they were typically called "NiMH/NiCd", capable of charging both the chemistries in the same way. My Maha C9000 also claims to be capable of charging NiCds without any special procedure or precautions for them. I think that the drop for NiCds is simply more visible for NiMH chargers without affecting the charge procedure in any negative way. Of course if the charger is not smart the situation is different but that's not what the question was about.

Great link thanks
