Good OEM Battery [Posted on 2008-07-06] I found the Ultralast battery to work well in my Canon SLR. I have only put it through a couple of charge cycles, but it seems as good as the original.
Good batteries for the price. [Posted on 2008-07-07] Bought two of them for vacation to DC. When they arrived one was dead and would not even charge, contacted the seller and they sent a new one in 3 days. Both batteries work great, hold a long charge, and took the DC heat walking the streets for 7-9 hours a day for the entire week. Only had to recharge one time for each battery all week. Would buy again no issues or reservations!
More capacity than expected [Posted on 2008-07-14] It says that they are 1200mAh, so it would be below the 511A (1390mAh) batteries.
However, I was pleasantly surprised when the battery, still at 7.4v is actually a 1600mAh files.
It seems to hold well, but I'll update the review later when I've used it more.
What's good:
- 1600 mAh (400 mAh more than Amazon states - that's a lot of photos! - 33% extra battery life)
- Works when Canon's charger included with 40D. The connectors on the back are exactly the same as Canon branded batteries.
- Cheap - buy 3-4 of these instead of 1 canon branded one - and get more battery life as well.
What's not so good:
The battery cap on canon's batteries is a little too big for this one, it 'fits' but falls off extremely easily. I was hoping to use the cap as an indicator of a charged battery, or empty battery, but cannot do that with this one.
We'll update after more months of use:
How well it holds the charge. So far, so good.
Doesn't last as long as original [Posted on 2008-07-20] Doesn't last as long as the original. It probably last about 300 pictures on my 30D (with review off the battery is shown low after 200 pictures or so, I guess it can still go on for a short while)
specs changed [Posted on 2008-08-01] Cheaper and it worked on my camera but be aware that the specs are slightly different from the advertized value. Voltage is 7.2 instead of 7.4
