Works exactly the same as the canon battery as supplied with my 60D, and lasts as long, so far, although not used it as much as original as this is my secondary backup battery.
This did work without any problems the first time I charged and used it, but since then I have taken it away on holiday for a week and it did not function at all.
Fully charged (left in charger for 24 hours) prior to the holiday and it functioned for 10 minutes at most allowing about 5 shots to be taken.
I would recommend a Canon product only, don't use these inferior products.
Trying to return this item for a refund is a nightmare, the company want me to return the item to them at my cost and then they will send me a replacement product which I do not want, the other option is to refund with a 20% admin fee. Why should I pay for the return and have a 20% admin fee?
OK at the end of everything, Amazon trying their a-z guarantee to try to help me with no success as the product was delivered correctly more than 14 days ago.
Fair play to Amazon they have tried but it is down to the seller to give me support and replace or refund, they have offered me 3 options;
1. You return the battery at your cost, and we replace with another Energizer battery as previously discussed.
2. You return the battery at your cost, and we replace with 3 Dot.Foto LP-E6 batteries (B003P58MHA
3. You return the battery at your cost, and we refund less a 20% admin charge (refund value £21.19)
Cost of returning the battery is between £6 and £18 depending on level of tracking and insurance.
I have decided to take option 4. Give up and never trade with this seller or any other seller on Amazon other than Amazon themselves.
I will never be buying unofficial batteries again, from now on it will be manufacturer products only. I have learnt my lesson, fortunately this lesson has only cost me £26 and a few phone calls and emails.
