how many & which ones.

Hi all,

I need batteries for my 40D from a u.k site.

I can't afford Canon at the moment.

I am going to trek base camp Everest in 2 weeks for 19 days so i need spares.

My questions

1, how many?

2, which ones?

3, how to store them during the day.

I appreciate any feedback.

Thanks guys.

I've never had a problem with 7dayshop ones but then I've never used them in extreme climates like Everest.

How many? Depends how much you're going to use your camera and whether you have access to power supply. At £10 for 2 7DS ones its up to you.

Storage. I'd store them near your body so that your body heat keeps them warm.

Not much help I know but good luck anyway

Thanks Neil thats pretty much how i have been thinking.

I will take about 6 i think and i have 2 already from 7day shop

When I went treking in Nepal it was back in the days of film, so things where pretty straightforward. Though some of the fancier electronic cameras did die in the cold.

But from my skiing experiences, modern cameras shouldn't have too much trouble with the cold at and below base camp. But if there are cold days, it would be worth keeping a couple of batteries inside an inner layer of your clothing and swap them in and out of the camera. The cold will shorten the life of your batteries. But put an apparently dead battery inside a pocket next to your body for an hour and it will magically come back to life.

You are unlikely to find much electricity for a recharge once you leave Namche Bazar, though things may have changed since I was there 10 years ago.
