MASS ORDER: Sanyo 2100mAh batteries and charger

I have a source who told me rechargeable batteries should be drained off completely before recharging. No matter what trickle charge mode, it will still hurt the batteries if they happened to be not discharged. I can't vertify the claim. So I rather be on the safe side, have standby spare batteries. Once one set is flat, I'll charge it. And also I charge it slow e.g. 5 hrs, to prolong the battery life.

to complicate matters further, i've read off some site, saying that discharging the batteries to a minimal point, batteries may become d-e-a-d.
the same problem as deep cycling of car batteries.....
no MO for this uh...Im more interested in Sanyo's Super Quick Charger, and sure many others do also

MAHA is superior to the Sanyo 2100 charger in many aspects
- charges the 2100 mAh batteries in about 100-120 mins (that is twice as fast as the Sanyo charger which takes 4 hours)
- 4 individual charging circuits compared to Sanyo's 2 charging circuits. That means the Maha 401 charger can monitor and charge each battery individually providing a more accurate and optimal charge. The Maha 401 charger can also accept any number of batteries (1 to 4). You have to charge batteries 2 by 2 on the Sanyo.
- Negative flex pulse charging algorithmn which only the Maha 401 charger possess which does conditioning (elminating any battery memory effect) whilst charging. Sanyo charger does not have any conditioning function.
- Maha 401 uses negative delta voltage detection which is currently the most accurate method for detecting if a battery has reached full charge.
- Maha 401 has cool charging function (which charges at room temperature, hence prolonging battery lifespan as excess heat can damage batteries)
- Maha 401 has 2 charging option to cater to your charging needs. Either fast charge at 100min or slower but cooler charging at 5 hours.
There's a reason why Maha 401 has been called the "near perfect charger" by a review from imaging-resource.com and being named one of the TOP 25 photographic products by PCPhoto magazine . Dpreview.com also constantly feature Maha battery product more than any other battery brand. The Maha brand in the United States is always associated as the top brand for battery solutions.
i'm not too sure if my previously-in-use charger (olympus quick charger) is designed similarly to the sanyo quick charger, but they look pretty much the same to me.
as for my olympus BU-200 charger - i read the specs at the back -
460mA x 4/920mA x 2. that means when i plug in two batteries, the charging time is probably over 2 hours to fill up 2 2100mAh batteries. but if i were to charge 4 batteries, that would take up twice the amount of time...
so guess what? i got the maha.
4 channels of 1000mA, all independent of each other.
say, any current owners of the sanyo quick charger, please post the specs of the charger up here as well, can?
here's the details for the olympus BU-200 charger unit:
Input: AC100V-240V 50-60Hz 8W
Output: DC1.2V 460mA x 4 / 920mA x 2

Charging 2 pieces of 2100 mAh takes 105 mins."
Dun have enuff tech knowledge to comment on the other pts
That's only for 2 batteries. Most of the time, ppl charge 4 batts at a time. For 4 batts in the sanyo, it will take much longer (4hrs?).
But maybe that's why the 401 costs twice as much as the sanyo 2100 charger.
Go check http://forum.clubsnap.org/showthread.php?s=&postid=238830 for the Last MO we are organising.
Forgot to mention that the Maha 401 also has trickle charge function which helps to "top-up" cells once a normal charging cycle is complete. Most other brand chargers will simply cut off the power once charging is complete, causing batteries will start to self discharge after power is switched off.
Quote from Imaging-Resource.com Maha 401 Charger Review
"The C401FS is a "smart" charger, which means it applies a high rate of charge to the batteries when first inserted, then cuts back to a "trickle charge" when peak voltage is reached. Fast-charge current is 1000 mA per cell (500 mA for AAA cells), about as fast as you'd want to dump charge into typical NiMH batteries. Once maximum charge is reached, the charging current drops to 50mA, a nice, gentle level that can be tolerated for long periods by most good-quality NiMH batteries on the market. - It's thus save to leave batteries in the C401FS more or less indefinitely, helping avoid the "self-discharge" of NiMH cells that would otherwise severely limit shelf life."
