battery speil from canon

[jann1033]

i bought some additonal batteries for my rebel but now see canon basically won't cover any damages to the camera if they blow up or something and hurt the camera.
so how often would that happen? they are 7.4 volt the new cheaper ones are higher for the other number( i think it's mAh.) 1000 vs 720 which i thought was just basically capacity? both look identical, cheaper ones say for can-nb2l 7.4v li-ion battery on the back...

That is a standard industry disclaimer. Sony camcorder warranty is void if you use other brands of media. Just do not tell them you use anything but authorized accessories.
I have never had a battery melt or leak in a camera. Let me rephrase that, never a rechargable battery. I am sure almost everyone has left alkaline batt.s in a flash and they go bad and leak corroding the end plates contacts.

Some aftermarket batteries have caught fire, melted, outgassed, etc. Most of these were for cell phones, not cameras, but that is probably because of the sheer numbers.

Some aftermarket batteries are very good, some not so good. Some do not have the same protections built into them as the factory batteries do. Which ones is almost impossible to determine.

Battery capacity can be measured in different ways to come up with about any capacity desired. Then there is the old standby, lie about it. A 10% difference porbably makse no difference anyway.

I do not like paying Canon's prices but consider it insurance. If my camera is destroyed by a battery Canon may cover it if it is their battery, but I hope I never find out.

Canon has every right to not honor the warranty on your camera if it is damaged by an aftermarket battery. And you have every right to chose to take the chance of voiding your warranty to save some money. That said, battery failure of a type that would damage your camera would be very rare. Most failures of rechargable batteries are charging related, either over charging or charging too fast. Your camera would only be at risk if you took a hot battery off the charger and put it into the camera immediatly. The chemical reaction that allows the battery to store electricity continues for a while after the battery is off the charger. This is indicated by the heat you feel when you touch a charging battery. The other issue with cheap batteries is false peaking. In other words, the charger thinks the battery is charged before it actually is. Then when you go to use the battery it doesn't have the juice to run the camera because it never truly got charged.

These stories are enough to convince me to use only Canon batteries in mt Canon dSLR. The problems *are* very rare but they appear to happen at any time, and most are due to counterfeit batteries.

buy the battery from Sterlingtek. My entire company (no, I don't own the company) use them and we've bought maybe about 20 sets of them (1 set = 2 batteries) for all our cameras and none of them had any problem whatsoever. We've been buying from Sterlingtek for the past 3 years. They are the more-expensive after-market battery seller.

There is no way I'm buying the overpriced original Canon batteries

the issues with some cheapy, noname, made overseas lithium ion batteries is they lack the circuitry that shuts off the charging and also when emptying. decent name brands, such as the Sterlingtek Kelly mentions above are high quality and have the appropriate circuitry. they are less expensive, generally slightly higher capacity, and i have found they have a better life. given that it's so easy to kill a lithium based battery through over depletion, it makes good sense.

for 1 series NiMH batteries, the few third party batteries that are out there don't always completely fit. since the battery contains a weather seal, i wouldn't risk it to save $50. i bought one and now only use it in emergencies. given that i generally carry 2 batteries with me and each one is good for a few thousand shots, emergencies seldom crop up.

in some states that type of warranty is not legal, they can not invalidate a warranty because you use 3rd party aftermarket parts...

 

[boBQuincy]

The Magnuson-Moss Warranty Act of 1975 states that a manufacturer cannot void a warranty simply because aftermarket parts have been used in the product.
The manufacturer may charge for repairs if they can prove the aftermarket parts caused the failure.

good to know..they said they'd take them back but i think i threw the box away....not too smart of me as far as made overseas,,Canon is made in Japan, other made in China...you know the same place where the counterfeit ones were made in the articles

 

[Kelly Grannell]

most of the battery cells are made in Japan but then assambled (put into the plastic case/bosdy) in China.
