Spare battery for 40D

[LongLensPhotography]

This winter is very demanding for the battery life. Yesterday my fully charged battery was drained in just 2 hours.

I am considering getting a backup battery that would stay warm in my pocket (no underpants comments please :nono.

Is a 3rd party job good enough? Are there any specific ones to look for or avoid? I doesn't have to be perfect, but should allow me to finish the job and do not explode or ruin the camera.

I use the Canon Battery grip on my 40D with
1x Original Canon Battery (shipped with body)
1x Aftermarket Battery

Never had any issues with either of them.
Even with out battery grip, the aftermarket one performs great!

Cheers

I have never had a problem using either cheap or genuine batteries when there is a "standard" type lens on the camera: Any will give me over a thousand shots without giving out. (I recharge my batteries at the end of the day so am unsure exactly how long they last.)
When I have found a difference is when I use the 600mm lens: Canon batteries will last me over twice as long as the cheapies.

for the non canon batteries.

I shuddered at buying non manufacturer ones at first but now I live on them.

7dayshop batteries last longer than the genuine Canons & are a shed load cheaper.

What about ebay ones? They have 2000mAh at a better price

I always use Ansmann and they are great. Get more shots out of them as well. Usually get them from Battery Force.

Just ordered 2000mAh ebay one from another guy for £5.49. I will see what happens.

Out of 7 ebay ones I have bought I have only had one dodge one.
Good luck - I am sure all will be well and you have just saved a packet!
