I was very absentminded when packing and forgot the battery charger. In fact I have 2 battery chargers at home (Australia) but NONE here! (Whistler, Canada). Anyone knows where can I get a cheap one here? Any good online shops with fast delivery to Whistler? I am on my second battery now and soon will be cameraless!! :(

if you are really bummin for a charger.... You could DIY yourself one from a cellphone charger.. just pull the phone end off the cord, make sure you correctly id the + and - wires, and fashion them to the battery. I would only charge for 10 minutes at a time. checking the condition of the battery in the camera. I'd also check the battery temp very frequently.
This my be a death sentence for a battery, idk for sure if it will work.
NOW, this is purely an idea of mine and i have no idea if it would harm the battery. It is just what i'd do if i were in a huge bind... with my spare battery.
just a macgyver try.. (i have lots of those) |

550D uses 7.4 volt batteries. Most cell phones these days use 5.1 or so for their 3.7 volt batteries. The charger wouldn't even have the voltage to accomplish the job. Some Li-Ion battery's charge controllers will also refuse to charge without a signal from an "authorized charger".
Mind you I have actually taken apart and jumped dead cells before :-p

I can't comment on the charge controller issue, as i have no idea about it. But the low voltage issue would just make it charge slower, not, not charge at all. |

This being DPC and all, maybe you could have a GTG with  ryanwest? He's less than 60 miles south of Whistler and has the same camera. ;-) |

| Thanks! I walked to Photo Source and they have a universal battery charger that will do the job. Not cheap ($59) but I guess that's the price to pay for not having itemized list of my photo gear! |

Wouldnt an uncharged battery create an undervolted load if its still above the charger voltage. If it try's to draw a higher amperage than the charger is rated for you might actually burn up the charger. I am no electrical engineer. But low voltage trickle charging is for cells that already have a pretty high charge.

I am not current (sorry) on the newest battery types/chemistries but I would be cautious about applying a charger for one type of battery to another. Some batteries will overheat if too much current can be drawn. I also don't see any way that a 3.7 volt output from a cell phone charger would charge a battery up to anything more than 3.7 volts (so a 7.4 volt battery would not get fully charged). You would have to probably tear into the battery packaging itself, separate out the two 3.7 volt cells connected in series, charge them individually without starting a fire, then reassemble them back into the package, connected in series again.
McGyver himself might just say screw it, and move on to Stargate SG1.... |
