    Default anyone using tis sanyo rechargeable charger too?

    does anyone kow about how long can this model batt last after a full-charged but doesnt in used at all... thanks ya!

    -------------------------------------------------------------------------------------------------------------------------



    i am really wondering how long does it take to be full charged?
    coz that two lcd lights are always on....
    if charge too long, i think the batt wil be spoilt... isnt it?

    and when i buy tis, i asked for extra rechargeable bat
    then that boss said tis panosonic's is compatible... isnt it?

    It would be helpful if you indicated the the type of charger. Guessing electrical specifications from the shape and colour of the case is not a sound method.

    If you turn the charger around, you should find the type designation. Not only that, the specifications (charging current) should be printed/molded onto the case.

    A good way of spoiling your batteries is to charge different types (particularly batteries of different capacity) in series, like what is shown in your photo.

    hahah.. thanks...!!
    Hahah! Isn't that funny!

    ooko... next time i will sparate them.. thanks ya
    coz when i bought it, i did read the guide carefully but it din stated normally take how long... and it is mentioned about the fully charged and low bat, the light will on or off (as wat i remm), but when i charging, the lights are always on...

    So, have you checked whether there is a model number or any specifications on the case?

    I have an el cheapo (freebie) Sanyo charger that looks like the one in your photo (type NC-MQN04B), but that one doesn't seem to have any battery-full detection or the like. Also, it definitely doesn't charge 2.7Ah AA cells in two hours, as its specified charging current is only 250 mA. But chargers with a similar case may have quite different specifications, so what I know about my charger may no apply for yours.

    yeah.. exactly the same model with urs... so... how many hours should i charge it (whenever 2 bat and 4 bat)? coz it doesnt have any notification when full charged as u know?

    thanks!!!

    That depends on the capacity of your batteries. Ideally, one would check the data sheets for the cells. As a rule of thumb, for standard charging with a current I=Q/10h (where Q is the capacity), it should take around 14 hours for empty cells. This would be the case for 2500 mAh cells. Cells with significantly lower capacity probably shouldn't be charged using this relatively "dumb" charger, unless you know what you're doing.

    The charge current (and thus the charging time) should not depend on whether you charge 2 or 4 cells (according to the specs, but I haven't measured it). Only charge cells of the same type and the same charging state in pairs.

    You should also be able to tell when the cells are charged because they should get quite warm.

    i dun un =.=
    so i charged it when it shown low batt from my flash, i meant i used it till finished... so mine is 2700, it means it should take at least 14h to get it full charged?

    As a rule of thumb, yes. You'd get the best answer from the battery data sheet, although it may be difficult to find.

    However, be aware that the batteries may not be drained just because your flash unit says so. NiMH (and NiCd) batteries generally operate at lower voltages than alkaline batteries, so battery warning indicators designed for non-rechargeable batteries may be misleading. When in doubt, don't charge unattended and check the temperature every now and then.

    Ehs, some chargers hor, you must put the two same pieces side by side. For eg, yours in the pic is

    1221

    Better to be

    1122

    Emm, I think that model of Sanyo is designed for
    1221

    That's the one which can charge 2AAA batteries one right.

    No, it's 1122. There are separate contacts in each slot for AA and AAA cells, so every bay can take AA or AAA cells. The cells on the left are connected in series (sharing the same charge current, so they better be similar in every respect), and the cells on the right are connected in series.

    i using this charger too. the led light will only goes off after 16hrs of continuous charging. we have to take note of the charging hrs of each type of batteries to prevent overcharging.

    eneloop 2000mAh is ard 10hrs
    normal 2700mAh is ard 13hrs.

    I have the same charger ... although I really haven't clocked how long it takes to recharge.

    Normally, I plug in my batteries at night before I sleep (at around 10p or 11p) and then in the morning (at around 6a), the two green lights are already off, and the batteries aren't even warm. This means, after reaching full charge, the charging system switches off.

    So it's pretty safe to leave the batteries in (well, it has worked for me for the past 6 months now).
