Hi folks
what sort of battery life do you get from the stock t2i while doing video?

Dave

About an hour to an hour and a half.

in a typical day of shooting, it costs me one battery charge to fill a 16gb card, and sometimes a little more than one battery charge

I will be filming 16 hours over 2 days, I am buying a battery grip can anybody tell me how many batteries I need and how long they take to charge? I will be shooting full HD video. Thank you.

Thank you.You would be better off starting a new thread on 60D battery life rather than tagging on to a discussion on 550D/T2i batteries. The 60D uses the same battery as the 5DII & 7D & in my experience I get through 6-8 batteries for a long day's shooting with the 5DII but I have no idea whether battery life is similar for the 60D.

I also use T2i/T3i with battery grip. Didn't really time it.. but if I start shooting in the morning, I will need to replace battery in mid afternoon.

One thing to notice is, when you see the battery gauge showing half gone, it's time to replace the batteries in the grip.

I also have 1400mAh high capacity LP-E8 for T2i. The one comes with the camera is only 1120mAh.

Hi,

I am about to buy a battery grip from amazon and looking to buy some extra batteries on ebay but not sure if anybody has come across them before

New Battery for Canon EOS 600D 550D LP-E8 LPE8 T3i UK | eBay (http://www.ebay.co.uk/itm/New-Battery-Canon-EOS-600D-550D-LP-E8-LPE8-T3i-UK-/290583189398?pt=UK_Camera_Batteries&hash=item43a81b9796) They are only £4.79 with a capacity of 1350 mAh which seems great.

The alternative is on amazon Maxim - 1350mAh Battery Pack LP-E8, LPE8 for Canon EOS: Amazon.co.uk: Electronics which is £11.25

I have never purchased from ebay before so I can't see reviews of people who have purchased this item.

Try the cheap one, if they are OK, result.
This is a good buy http://www.ebay.co.uk/itm/BATTERY-GRIP-CANON-Rebel-T3i-EOS-600D-SLR-4x-LP-E8-/200594217751?pt=UK_Camera_Batteries&hash=item2eb458db17
I have purchased from them before, found them very good

You can get a cheap battery grip that has an LCD clock & has a built-in interval time which is handy if you want to do some time lapse sequences.

I would try a couple of the cheap batteries too. If they work then great, if they don't last as along as a proper Canon then you have still only spent less than a tenner.

I have four of these batteries which are claimed to be 2000mAH but I can't say that I have noticed that they last any more or less than the proper Canon batteries that cost three times the price. Opteka LP-E8 2000mAh Ultra High Capacity Li-ion Battery: Amazon.co.uk: Electronics

Hi,

Thanks for this, I am having real trouble getting a decent reviews for any battery. The most popular replica battery on amazon only has 7 reviews and even they are mixed. I contacted the ebay seller but reading a few other forums I see that those batteries give people real nightmares. It seems like most people just go for the original to be on the safe side.
