it completely killed one of my canon batteries.  will not charge anymore.  I suspect it pulled the power from on battery to charge the other when I put two batteries in the charger.  I don't dare use it again.  Replacing a canon LPE6 with another canon battery is very expensive

I bought this as a back-up battery to the official Canon one I received with my Canon 6D camera because I had read good reviews about it on this site but the battery stopped working about 11 months into its life. It just stopped getting fully charged one day, not going past the initial low battery indication and when I inserted it into the camera in its not fully charged state,I saw scary error messages, so I immediately  discarded it. I probably had fully charged it less than a dozen times as I was using it as the back-up for the included Canon battery which, by the way, is still going strong. I ended up buying another Canon battery to replace this one.  To be honest, I probably did get $13 worth of use out of it but it's not equal to a real Canon battery, by any stretch of the imagination. Yes it works in a Canon 6D but not for long. It's a good thing I wasn't planning to rely on it on a night shoot in winter or something. So, in this case, you get what you pay for.

I purchased these batteries as backups for my new Cannon Vixia HF R200.  The camera did not recognize either battery, rendering them completely useless.  Spend a little more money and buy a battery from a more reputable dealer.

One of the battery ports won't hold a battery anymore. Causes problem with the camera. It ends up only being a different handle.

This product lasted until the initial battery charge was depleated.  Camera never did charge the battery and will not play nor record off the plug-in cord for power.  Call canon and they want me to send the faulty product back at my expense so they can fix it.  It's only two months old and should not break down ... actually it was already broken when I got it ... just didn't know until the battery went dead and so did the camera.  I find it troubling that I have to pay for shipping and insurance to have a bad product that was sold to me just so I can have it fixed.  This is the second and last time I will buy a canon product.  I previously bought a high dollar Canon EOS 5 and it also had to be fixed.  Guess Canon doesn't have a quality control program in place.

This bad rating isn't against the merchant that sold me the faulty product, but rather it's against CANON !!!

Batteries will not charge easily.  Have to fool with the in several different chargers to get them to work.  I have several canon bodies with both canon and third party chargers and it is the same no matter what charger I use.  No problem with wasabi or canon batteries

Did not work with my Canon Camera (mentioned on the tem description). Avoid Buying it !!

These batteries are crap.  I have a Canon Rebel T1i.  For 18 months I have been using one Canon battery and two Vivitars.  All will let me take a minimum of 1000 pics.  One of the Maximal Power batteries only holds a charge for about 300 pics and the other goes to half charge after about 5 photos and then starts to flash like it's almost empty after just a few more.  So it basically doesn't hold a charge at all.  I wasted $20 and I still need batteries.  I'm not a happy camper.

My experience was after recharging the battery provided on this deal 2 times it will no longer power my camera. When installed camera says low battery and shuts down but in the charger it show battery is fully charged. After many tries it will no longer power my camera.  It worked fine at first try burnout now

Bought this three years ago when I bought the camera.  My Canon stock battery won't charge and won't turn the camera on, this battery will.  What more can I say?  Buying another one I guess!

This time I got a dud.  I have always used Canon Brand batteries in my camera's and have been very pleased.  But this time I got a dud.  Worked initially, but now 3 months later with light usage, won't even take a charge.  Sending back to Canon and hopefully they will replace it as these batteries do have a 1yr warranty.

Charged battery in new Canon charger. Put in camera when fully charged, Canon 7D registered it as a dead battery. Repeated. Same result. Original Canon battery works fine. Camera works fine with Canon battery. This was defective out the door. What a hassle to have to return. Best to stick with Canon. How many times do I need to learn that lesson?

I wrote a review earlier that said basically, its "OK" as a back up", but it is not even close to the canon OEM battery.  Now I am convinced that it is not even that good.  Don't believe the reviews that says its great.  Mine does not even function as a decent back up.  It has no shelf life.  I think I had charged it only a couple weeks before my last trip.  Then when I went to use it, it was completely dead.  Last night I charged it fully and when I went to use it today I got the low battery warning after about 10 minutes of use.  Next time I will buy the OEM.  I am now skeptical when I read positive reviews of products.  In some states, here in the US, they are starting to go after companies that post false reviews of their products.

I use this as a backup battery for my Lumix DMC-1.  I have charged it probably 4 or 5 times to take along on trips so that I can switch out my battery without needing to find an outlet for the charger.  This last week I charged my primary battery (that came with the camera) and this battery, packed this into a waterproof bag with spare memory, and packed my whole camera rig into my backpack for a 3 day backpacking journey into the wilds of Wyoming.  When I got to the first scenic view I grabbed my camera to shoot and realized I forgot my primary battery.  I smiled, realizing I had just charged this backup battery and had it.  I put it into my camera, turned on my camera, and nothing.  This had no power, in the middle of nowhere, with my primary battery many hours of travel away.  I was completely out-of-luck.  When I finally got home I confirmed that this battery started "charging" again, and that my camera was still working fine with the primary.

The most important feature of any camera battery should be reliability.  This battery screwed me over pretty good this weekend.  Please consider this before you trust it.  I am putting in an order for a Panasonic Lumix battery.

Both of the batterys started to melt inside the camera. Now the camera is broken. If I left the 2nd one on the camera pretty sure it would of caused a fire. The first battery (The left one bearly melted) one made the light flicker on the go off.  So I tried the 2nd one nothing. Then I smelled the burning plastic and found the problem.  Do not trust this battery in your house.

I purchased from Eastcoast Servs. I received two genuine Canon batteries in original packaging with manual. Both batteries were fully charged upon arrival.

If you are thinking of buying cheaper batteries by another brand DO NOT DO IT! They may be cheaper, but don't last long at all. Canon batteries slowly die off over the years which is expected. All others I have tried slowly die off for a few months then one day completely stop working. It sucks to charge the battery and the next day go to use it and you get nothing!

Item came via USPS and signature was required so I missed the delivery and had to pick them up at the post office. It wasn't a problem, just check to see if signature is required when you order.

I bought this ink and it locked up my Canon printer.  I've now had to spend $100 plus to try to fix it and when my specialist could not fix my printer, I had to buy a new printer.  I installed this ink into a perfectly good printer and it locked it up.  Do NOT buy this ink!!!
