Question: How long does it take the canon battery charger CB-2LY to charge a NB-6L battery?
Document: Canon CB-2LY OEM Battery Charger for NB-6L Li-Ion Batteries. PowerShot D10,...The battery charger Works like a charm, great item
This sure came in handy on vacation. It didn't take very long to charge the battery and I always had a spare with me. Worked out great!
The charger worked perfectly with my camera. I does not take a long time foe cameea to charge. I received it quickly.
I have multiple different Camera. You need an extra charger for each camera. Love the product because I had batteries go out on Canon. I like the peace of mind to be able to charge the battery with this extra charger rather than not take a picture.
It's sleek and small, and the plug folds in for travel. It charges the Canon NB-6L battery in a short amount of time. Indicator lights tell you when it's charged. It does what it's supposed to do, and there really isn't much more than that to say.
This was bought to charge a camera battery. It works just fine and will hopefully continue to work as long as we have the camera.
I purchased this battery charger for my Canon PowerShot 1300IS and am returning it as of today. When I inserted my battery, it took about an hour to &#34;charge&#34; and showed a green light indicating the battery was full. However, when I put the battery into my camera, IT DOES NOT WORK! !I've tried this charger with my other Canon battery and it doesn't work either. This is a faulty charger. DO NOT BUY! !
I used this to charge a battery once. The camera, and battery, is a back up. When I went to recharge the battery a second time, after a year, the charger no longer worked.
This product is a knock off. It stopped working on the first try! It's misleading because according to the title it sounds like an official Canon product but it is not. Just submitted a return request...we'll see if they take it back. DO NOT BUY!! Mine did not work at all.
Didn't work at all. Tried to charge battery- never got it to work. Lights never lit up, battery never charged.
Answer: I usually give it 3-4 hours ahead of when I'm going to be taking photos...it's more of a "play it safe" thing I do.  So sorry, I can't give you the exact time it takes.  Normally, I plug it in the night before I need it.
