Whats better for charging & conditioning

[PEU]

Im trying to decide which charger is better for conditioning old cells and charging new ones (eneloops) the Maha C9000 or the Lacrosse BC900.

Whay do you guys suggest?

I'd like to know too.

I've heard that the Lacrosse BC900 works very well (when it's not busy catching on fire )

I own both and prefer the C9000 as it has more charge/discharge rates to choose from.

You would benefit from doing a search for "C9000" . The are several threads which have the answers you are looking for.

FWIW. I have both and much prefer the C9000.

I read most of the long threads on both chargers, my problem trying to decide is the information overload...

The user interface on BC-900 is better IMHO. Also, the current x time comes together on the BC-900.

My MH-C9000 right now has significant discrepancy in displayed value and what it shoiuld be.. (charging for 10 hrs at 270mA should be 2700mAh, displays 2410mAh cumalative)

For another option look at

The C9000 never stays at the exact ma input setting anyway.

That's understandable, but what's bothersome is displayed current x time not being close at all to what is displayed.

Do you mean timer if off too or mAh?

Hello Pablo,

Here is a comparison of the two.

I would suggest the C9000 because of the Break-In mode.

Concerning the questions above on MH-C9000:

1) The displayed charging/discharging rate does not include a ~10% off-time. For example, when you set current to 2.0A, it will charge at 2.0A for 90% of the time and rest for 10%. Of course, the capacity reported includes this effect.

2) Time base is quartz based and is not a significant source of error (for comparison, BC900 uses RC circuit which has a substantial errror).

3) Capacity is calculated by integrating current over time.

BTW you can find these answers on the other C9000 threads.

Well, in true CPF spirit I purchased both, they will replace my two old & trusty maha204F's

i would choose the 9000, but run slower than FUll rate, cause it can run a bit faster with approx 50-50 type pulsing. like at 1000ma the 900 is mostly ON pulses. At the same 1000ma, the 9000 should be 50-50 pulsing.

has more space between the cells, and the "improved" programming sounds like it would be more sensitive end detection.

but Mostly cause it can be set to discharge at something more than 1/2 the charge rate. sooo slow sometimes on the 900 argg.

I just got a few AA and AAA Eneloops and the Maha C-9000 charger. So I take it you recommend running the Break-In mode for the Eneloops?

This issue was discussed in a number of the previous threads.

Can you give me some links? I have searched for "eneloop break-in" and "eneloop new" and "eneloop setup" and "eneloop conditioning" and this thread was the only thing close.

Sorry to bother you old hands, but I am fairly new to this, but am not lazy and have searched all I can on CPF and Google in the wide, wide internet world. I bow to the knowledge here. Links would be nice and not just "previous threads" condescension, or maybe share the correct "key words" for my searches???

Again, I am not lazy and have searched for about 6 hours over the lost three days.

Thanks.

Hello Mtn Dance,

The Eneloop cells are new, and they don't seem to benefit from the "Break-In" charge. It doesn't hurt them, but I have just been using them right out of the package. When we finally get enough cycles on an Eneloop cell to run it down a little, it will be interesting to see if the performance improves with a standard charge.

HI Tom,

Thank you for the direct reply, I really appreciate it. I will continue to search your posts for information on the Eneloops in particular, as well as your battery and charger analysis. You directly influenced my purchase of the Maha C9000. Thomas Distributing should be paying you a commission!

I'd like to add my voice of thanks for the vast information service you contribute to CPF community. :bow:

Tim, I put "eneloop break-in" in the "Google-CPF Only" search box on top, and got this string of replies. If there were not at least 20 immediate responses, I could understand your not being able to find it.....but come on man....at least try to make an effort.
