Battery grip and chargers

[jalafer]

I'm considering buying a battery grip for my 10D, but i have one question before. The grip uses 2 battteies and my charger only charges batteries 1 by 1. So, what do you do ? Did you buy another charger for charging 2 batteries at once ?
If yes, I have to buy the grip and the new charger, also 1 new batteries and another 2 for the back up.
Am I right ? If all this is required it would be a lot of money all together.

i usually throw a battery on the charger before i go to bed and then another as soon as i wake up, by the time i'm ready to take the camera out both are charged ;-)

yeah the charge quickly
and if you ever have just one battery just run on it
altho i've slowed down taking pix this month I've had to charge my batteries twice. So you rarely need to charge.
I have 3 batteries so i can cycle thru them.

dont mean to hyjack your thread, but its on the same topic of batteries and charging.

Is it ok to leave the battery on the charger over night? will it overcharge it after the light on the charger is solid?

Also in the manual it says to keep the battery on the charger for 1 hour after it reaches a solid red light? is this necesary or do you do this just the first time you charge the battery?

Thanks

I do them one at a time and it takes some time, but then again so can processing several hundred pics!

Leaving them on charge overnight, I just did that last night (read 7 hrs) and no harm seems to have come of it yet. Once the light goes solid you can leave it on there for another 90 min to really charge it. I don't see any harm being done. If it is anything like the batteries in ham radio equipment, you can leave them on forever and they trickle charge after a certain amount of time.

The chargers are "smart" and will not overcharge a battery.. so yes you can leave them overnight.

I'm a heavy believer in redundancy. I have a DRebel and a 10D, each have a grip, each grip has two batteries, so I currently have 4 batteries and two chargers.

However, this only results in one set of spares, and I'd much rather have redudant spares, so I have four more batteries and two more chargers on order.

The chargers aren't that smart: they don't know warn you
when you need to clean the contacts. My charger behaved
erratically one day, and turns out the contacts were dirty.

Unlike battery and camera contacts, which remain concealed
most of the time, the charger contacts are open and constantly
exposed to dust, moisture, spiders, etc. Make sure you clean
the charger contacts frequently or else they might strand you
powerless one day, when you're least expecting.

I hate it when spiders go mucking up my battery contacts :lol:

What do you use to clean electrical contacts?

Also, how do you remove corrosion from a battery compartment (not related to any of my photog equipment). This question comes from having a 3-yr old that left a toy under the deck.......
