Batteries and chargers

No. Green light indicates that the battery is fully charged. You shouldn't take it out.

Well, I think the answer is in the question...

Either the charger is bad, or the batteries are. Have someone qualified check the charger voltage.

Replace whichever is bad.

Thank you for such a detailed description, wishing others would take your lead. To the problem camera designated batteries (other then AA rechargeable) have always been a bit of a sore spot for me because the user is compelled to purchase a specific battery. As much as I prefer the name brand accessories for the camera there come a point where you just gotta venture forth with third party accessories. There is nothing wrong with using an "off" brand in fact what I've found is that is some cases they are a better battery. Again back to the problem. I grasping thoughts on how to word this but, here goes. As much as the manufactures would like you to believe that these batteries do not form a memory they do. Also the battery can trick you into thinking it's fully charged when in fact even though the charge light is saying completed it's only got about 1/3 charge. I've worked with Canon's BP 511 and now the "new" BP 511A for many years The BP511A or equivalent is the better battery. What needs to be done is to drain those batteries down until they stop, let it cool don't take it from the camera to the charger. Time the battery when you put it on the charger, meaning not to the second but what you would "normally" do is plug the battery into the charger and leave it right. Well what's possibly happening is that within ten minute the ready light is coming on, (something stupid going on in the battery) So check the battery stat of charge after say 15 minutes and if it says it ready (drum roll please) remove the battery unplug the charger for a few seconds and place the battery charger back onto the wall outlet and plug the battery back into the charger and look at your watch again. I've had to do this as much as three times until the thing would get the idea it was to take a charge "normally" about 2 hours will bring it back up. There is no device I've found to completely drain one of these batteries so over a period of time in your case one year the batteries begin this fit. I've since replaced the BP511 for the better BP511A's or equivalent. I'm not pointing a finger because myself and staff do the same thing and pull the battery before going to a shoot if it's showing partial discharge and the thing gets put onto charge and we start this cycle all over again. Be careful of the charger as well meaning don't just disconnect the battery and put it back on charge when it's going the cycle thing disconnect the charger from its power source as well because it holds a memory for a few seconds and will just shut off in a few moments if you don't.

Long story but I've been doing this now for 9 years since the dawn of Canon's 30D Cheers

The flashing red probably means that the charger is working correctly and is indeed charging the batteries. The light should turn green when charging is complete after anything from 1 to 16 hours depending on how this charger works.

Do the following test: Fit the charger with your batteries and connect it to the mains. After 1 hour check if there is a detectable temperature rise in the batteries. You can do this without interrupting the charge cycle by touching the cells with the back of your fingers. If the temperature is still low, let it continue for another 15 hours or so, checking every now & then for any temperature increase. Should the temperature rise more than a few degrees, then stop the charging by removing the charger from the mains. Should the red lamp remain flashing after 16 hours, then I suspect you to have a defective charger.

You can find a new charger by searching for your camera's model number (add the word "charger") on Amazon, but it might be better to get one of the "universal" chargers instead. There are several makes of these, that will charge any of the small lithium batteries used in cameras and phones, so you won't have this problem again. And the universal chargers are often cheaper than the ones dedicated to a single battery type.

If your camera came with a charger for the battery, then it is unlikely that it will charge from the USB lead.

You may want toget a battery that "New Canon BP-808 Equivalent Li-Ion Rechargeable Battery. Rated with 900mAh, the battery is made with info-chip, which can show remaining time on camcorder LCD. It also can be charged by Canon original charger and camcorder. It works wonderfully for and is 100% compatible with:

You really don't need to buy Canon batteries. Any replacement AA rechargeable batteries rated at 2300 mah or better should work with your charger.

A few solutions for you:

1) The batteries that you are using may have reached their end of life.

2) You are using higher capacity batteries in a charger that was designed for lower capacity batteries. The charger may be a 1 hour charger that was designed for say, 1500 mAH. If your batteries are 2000 mAH, then after the same hour, the batteries may not have a full charge, and will be damaged if this were the case, and the practice continues.

3) You are using a combination of batteries and charger that isn't compatible. For example, NiCD chargers cannot charge (usually) NiMH batteries, and vice versa.

4) There is always some drain by the batteries themselves, just being rechargeables. Though, this is usually on the order of 5-10% per month, and probably is not the issue.

I would put my money on saying that the batteries are worn out. Try a new a new charger / battery combination. If that works, then either the old batteries or old charger are defective.
