High quality Canon NB-4L replacement lithium-ion rechargeable digital camera
Better than expected!, 2008-11-02
I bought one of these as an emergency back up for my Canon Ixus 70 before going to Glastonbury this year, thinking that worst case scenario I would get enough battery life to take a few pictures if the original battery gave up on me after a few days.
I actually didn't need to use it on that occasion, but I have since and I can assure anyone who's wondering that it is just as good as the original battery packs Canon provides (and sells as replacements for £20). The battery achieves a full charge from empty in about 2 hours, and then lasts just as long as my original Canon (for me this is usually a matter of weeks, but obviously it depends on your usage so may be a longer or shorter length of time).
Overall I am very impressed with this as a back up, especially when one considers the difference in price between this and the 'genuine' Canon products.

best batteries ever, 2008-12-23
Found these batteries to be much better than the rivals, when using with my digital camera I rarely need to change them. Also work fine with a different brand of re-charger. I can find very few places to get them other than Amazon.

Battery for Nikon Cameras..., 2008-08-22
"Spare" battery. Pretty much essential for all but the most casual of users. So, if you're using the likes of a D80 and above you're probably a "keen amateur".

Battery. Extra. Genuine Nikon Brand. Good price.

Done.

Cheaper alternatives available, 2009-01-03
There are a few high quality alternatives to this battery manufactured by Energizer and Uniross that are significantly cheaper. They might be worth a look. While this Canon replacement is no doubt of a high quality it, like most other own-brand replacement parts, is over-priced! Try Google Product Search.

• safety due to heat and overcharge protection
• real lithium-ion rechargeable battery, more power than the original rechargeable battery
• no memory effect ? recharge your battery whenever you like
• excellent fitting accuracy, certified quality merchandise, not an original accessory
• the standard battery charger can still be used

OK as backup, 2008-11-29
First thing that struck me about this battery was its weight - the original lumix battery weighs 24 grams this one weighs 16 grams: fits perfectly, seems to work fine, after 15 minutes continuous video recording the batt indicator on my DMC-TZ5 had gone down one bar, two thirds the weight - lasts about two thirds the time of the original, for the price a good backup battery.

Spare battery....nuff said., 2007-10-23
I bought a spare one of these for my 5D.

It's rated at 1390 mAh and 7.4V. As it's an official Canon product it won't invalidate your warranty if that's a consideration.

These battery packs give a very high number of shots and I feel confident with two of these fully charged I can shoot all day, review photos to my heart's content and use battery draining IS lenses without worry. In fact I've only had to change batteries on one occasion and by that time I'd had enough anyway! I think they are rated to give around 800 shots.

Highly recommended.

Definitely worth the money, 2009-01-09
These batteries are great - I combined them with the Duracell Value charger to save money overall and can definitely recommend this method - far better to have great batteries that charge in 6-8 hours than a one hour charger and not such good batteries!!
