cheap batteries on ebay

[skimmilk68]

i didnt want to buy a big bulky batter grip so i wanted to buy extra 300d batteries on ebay. Compared to what I've seen in other stores, they're WAY cheaper...

the one on ebay is 1800 mAh and the 300d battery is 1100 mAh.. would that cause any damage on my camera?

The original Canon BP-511 battery was rated at about 1100 mAh. The newer ones and BP-511a ones are 1500 and 1800 mAh.

There is no problem with using one of 1300 or 1500 or 1800 in any camera that calls for a BP-511 or BP-511a pack.

On the other hand, the bigger capacity batteries might have to stay in the charger slot for a little while longer to store up some extra charge.

The extra mah just mean that they have more power and should last longer. What mah stands for it milli ampers/hour, or how many milli ampers it can supply continuosly for 1 hour. So 1100mah is 1100 milli ampers for 1 hour, 1800 mah would be 1800 milli ampers for 1 hour of continuos power draw. With batteries the thing that will cause damage is if the voltage is incorrect. you wouldn;t what to use a 9 volt batter on something that was only suppesed to you 2 AA's since 1 AA is only 1.5volts or 3 vlots for 2. But if you could fit 2 D size batteries in something that was only supposed to use 2 AA you wouldn't have to change them very often because AAA, AA, C, and D size batteries are all 1.5 volt batteries. The difference is the mah they can output. Hope that helps.

I have these batteries, and have been using them for seven months. They rock. They hold a bit more of a charge, than does the 1100 battery, and just as Bob said - it won't hurt your camera.

I haven't noticed them taking any longer to charge than the BP-511 that came with my camera, but then again, I haven't checked... but then again <grin> when I want my battery, I want it now! So they must've been pretty quick to charge.

I do have a battery grip for my camera, and I also have six batteries. Four from Sterling Tek. I've recommended their products to others in my photo society (those N*kon people hahha). We've all been using them, and I've had a ton of people thank me for turning them on to the batts! Btw - if you don't want to do the Ebay dance, just go to http://www.sterlingtek.com/.

In my battery pack, two batteries. I have shot a county fair from 0800 to evening, flash on/off... and an entire rodeo (2.5 hours at night, lotsa flash). Over the course of the day - probably 2 - 3 gigs of high res jpgs. Lotsa families, kids, inside barns, action, etc.. My battery pack level seems to not even have been touched.

In London last month, I shot for two days (2 gig per day of high res jpg - yes, I have a trigger finger, but I'm also a voracious learner) - and again, my batteries were still showing no sign of waivering. I charged them at night after day two because I didn't want to gamble and suffer because of lack of power.

I shoot every day, and charge all the time... no sign of failure. make the purchase, you won't be sorry.
