solution - overheating

I was talking to someone today and the subject of overheating came up and they
were saying how they had to wait around for 10 maybe 12 minutes.

I was shocked, then I realized that he thought the overheating was from the sensor.

It's not. (And maybe I thought there might be some dvxusers who don't know this as well so here I am posting)

I told him the heat is from the battery. All you have to do is have another charged
battery with you. Switch batteries and you can keep shooting. The one you remove
from the camera will be hot but still have a charge so you can put it back in when its cool.

So you will still get overheating warnings but at least you are only out of action for as long as it takes
to change a battery.

Just keep switching them or just use the canon power adapter/cable

Ever since I put my Canon to shut off automatically every minute when not in use I have never gotten the overheating signal again.

Also I noticed after I bought a battery grip it helped as well
 
Thanks for the tip, J. :thumbsup:

I will offer a word of warning to T2i users and potential buyers…..my camera has been flashing the overheating warning lately. (It's been like 90-100 degress in Connecticut) Just be prepared if you're out in the field shooting important footage. I would hate to see anyone lose anything good cuz their camera died.

Yes the battery is part of the problem from what we've experienced. Here in Florida it's pretty much hot 24/7. Swapping batteries and to leave the battery door open has helped, but after the inside has been heated up it's best to just leave it off for a few minutes if you're shooting outside or in hot environments. We've also used ice packs wrapped with a towel.

this is a crazy idea but maybe you could try keeping your batteries 'on ice' or at least
colder than normal so when you do a swap they take away heat even more
 
Not sure if I buy this. I had one overheat warning at a studio shoot and I was using the power supply, not the battery.
 
This might be a pretty silly question, but you can plug the 7D directly into an outlet for power? I don't recall seeing any power supply or anything when I bought the camera. Do you have to buy it separately or something? Thanks for the info.
 
ACK-E8 and ACK-E6 are the power adapters for the t2i and the 7d

I have shot a 7d under 2.5k of hot lights with a power adapter for two days straight (20hrs) with no overheating warning. Maybe I had a lucky camera. Tomorrow I have a long day shoot on a power adapter with a t2i but cool lights not hot lights so I guess I'm going to find out how well it handles on a tether.

It may be situation dependent and maybe one camera overheats more easily than another. But the battery swapping trick has worked for me.

Sorry a little off topic but anyone find a cheap-o chinese ac adapter for the T2i?
 
I've done the battery trick as well.

Shooting on a hot day (100°F) in the direct sun, my T2i started overheating. I turned it off for 30 sec, let it rest and tried again. It over heated in less than a minute. So, I popped the battery out (it was hot) blew some air in the battery compartment to cool the body down some and let the battery cool for about a minute. Since it was the only battery on-hand, I then put it back in was was able to shoot till I filled up my card. I did turn the camera off when not in use.

So, pulling the battery out does help cool down the camera.

I don't think putting the batteries on-ice is a great plan, most batteries perform badly when cold (maybe they would warm up and be fine). Keeping the batteries cool sounds good, just not ice cold.

Note: Turning down the brightness of the LCD also helps keep the camera from over heating. I keep mine set like 2 clicks below medium.

The batteries are part of the problem, the other is that it's weather sealed and I think the camera's hardware also increases the heat. Not sure if the battery on ice next to my blue moons would help or not. :)

Or a camera that might not be completely sealed...

just finished a shoot with a t2i that overheated on a power adapter
I switched to a cold battery and kept shooting, only downtime was 2 mins to change to batt

just thought ya'll should know
 
I've been using a bottom grip and haven't overheated yet. I imagine it helps keep some of the battery heat away from the cam's guts.
 
oh this thread popped up on my radar again

I'm using the cold battery trick on every shoot now for my vampire short

it's in an apartment so we have the fridge off but its still cool

swapping batteries on every card dump

when I say 'cold' battery I should really say 'cool' its not like they have condensation on them !
 
also using some kind of support system where u dont have to hold the camera i hear helps. duno how true that is but....
 
Heat warning came up on my 7D under partial to full sun in 80 degrees-ish temperatures. Took the battery out and stuck a fully charged one in that was from my backpack.

Heat warning was back within 1 minute. Battery I took out wasn't that hot anyways...

Obviously removing things that have absorbed the heat might mitigate it some, like the battery, or the CF card, but the heat itself is not caused by the battery I don't think. I'm fairly convinced it is the live view that causes internal heating with the external conditions being the deciding factor on if the warning comes up. Hot weather/direct sun/hot room full of people or similar will likely invite the overheating warning.
 
Hey Ryan, I think if you are in a situation such as you describe where direct sunlight is causing the heat issues then swapping batts will not help.

But I assure you, after 8 shoots in the last two weeks, indoors with AC running between takes and using flos and LED's (no hot lights) the cams overheating is caused by the battery.
Without a doubt. 100%. Taking them out they are so hot almost uncomfortable to touch.
