I've got a PowerStation TC Max from <a style='text-decoration: underline;' href="http://www.Hahnel.ie" target="_blank">www.Hahnel.ie</a> that came with 4
2000mAH NIMHs in a set (a slow 10-11 hours charger w/t timer).

Will it charge their new 2350 mAHs properly when I see the new
charger is 230mA and not 200mA as my charger is? Or will I have to
get a new charger if I get the 2350s?<!-- ~MESSAGE_AFTER~ -->

As for original question goes - it's perfect. It doesn't matter, which
capacity you have, it's voltage which matters, but this is always 1.2 Volts
for rechargeble and 1.5 volts for Alkalines. It's just higher capacity,
longer shooting time without recharge.


To Rolf:
new batteries with 2350 mAh will be just fine, they will however need a bit
more time to recharge. Normally you calculate charging time as capacity /
charging current and add about 40 %. Which for 2000 mAh set goes 2000/200=10
hours, plus 40% is 14 hours. Your batteries (2000 ones) are not fully
charged after 10 hours, if charging current is 200 mA, even if it says
so(note that they get warm, which means that some amount of loss is
present). Leave them in at least 14 hours . While 2350 ones will take
2350/200=appr.12 hours plus 40%=appr. 17 hours. It's just when you charge
batteries with high current, you must monitor voltage and temperature, while
all this is not needed if charging with low currents.
However, note that NiMH batteries quickly self discharge - about 1 % per
day, which means that if you leave them for a month, they will have only
about 70 % of charge left. So, it's better to get yourself some smart
charger, which after set time switches to "trickle" charging (slow - 50 - 80
mA), so, in such charger you can keep batteries in all the time and they are
always full. Like one slow charger from GP, which has 18 hours timer and
after that switches from 150 mA to about 60 mA (i have 1800 mAh batteries).
In such state i can leave them connected for month or longer. When i need
them i take them and they are for sure full.
But, at the end, some quick charger can at the end of batterry life
sometimes extend their lilfe, since hi current can wake-up dead batteries
back to life for a while, so maybe you should consider to get some quick one
(like 3 hours or 1 hour type).<!-- ~MESSAGE_AFTER~ -->

I forgot to mention... Since you have this camera, you probably already
noticed that it's hard to focus in low-light indoor conditions. I solved it
with small hand-held laser pointer with filter attached (some heart or
flower will do). Try it and see. Result is excellent. Just watch out where
you point it!!<!-- ~MESSAGE_AFTER~ -->

Hi Sleeperman,

Could you please explain in more detail about how you use a small
hand-held laser pointer with filter attached (some heart or flower
will do)??????????????/

Thanks.

Bill, this was posted back in 2004, so you may not get an answer..

But what he means, I think, is that you can buy little laser pointer
things that project a pattern (eg heart or flower), instead of just a
fine point. By having such a device to point at your subject when
autofocussing in low-light, you give the AF something much easier to
'see'. Sony cameras use such a system for their 'laser assist'
focussing, instead of the usual pre-flash or red-led.

This makes sense to me. I might try it sometime. Thanks for explaining
it to me.
