This battery is made from top quality JAPANESE CELLS and is FULLY DECODED allowing your camera to correctly display the battery level on your camera LCD. Lithium-ion batteries do not suffer from the adverse memory effects that are normally associated with other battery types (meaning you can recharge a Lithium-ion battery from any level without affecting its battery life). STK BP-511 is a rechargeable Li-ion battery providing 7.4 Volts and 2200mAh of power to select Canon digital cameras. STK's BP-511 battery can be charged using the orginal Canon charger or the STK Canon BP-511 charger. Compatible Models: Canon 10D, 1D, 20D, 300D, 30D, 40D, 50D, 5D, D60, Digital Rebel, G1, G2, G3, G5, G6, Pro 1, Pro90.

Review: Excellent quality, unbeatable value. I am an OEM-Only kind of guy, but I am now re-thinking my position when it comes to STK. - These batteries are awesome. SterlingTeK has a quality reputation for a reason. These last for twice as many shots than my original Canon batteries, with flash on and LCD at the highest setting. They are solid, sturdy and are of quality construction. The price is unbeatable and I would recommend them to my friends and family. The product is excellent, and the value is unbeatable. That being said, here is a small course on rechargeable batteries and how to get the most out of your batteries for all of your devices: ----------The rest of this review is more of a guide to rechargeable batteries---------- I recommend charging them fully as soon as you receive them (this is common for battery break-in procedure, as sometimes they discharge while on shelf and during shipping). Then after you've fully charged the battery, allow the battery to get to zero bars before charging the battery again, for proper battery conditioning / break in / calibration. HOWEVER, NEVER LET ANY BATTERY COMPLETELY DISCHARGE to the point of your device turning off! This is horrible for battery life. If you accidentally allow this to happen to any battery ALWAYS charge the battery IMMEDIATELY. This way you will extend the life of the battery. I have done many hours of research pouring through battery testing PDFs for all types and variations of batteries, for all kinds of devices. Yes, I know that many manufacturers claim that this is not necessary but I have found that ALL of MY batteries outlast those of my wifes and kids' devices where I had not had the chance to do this break-in for them. After this first battery calibration that I detailed above here is what I do, based on what I've found from extensive research: I always charge my batteries when they get low, but not dead. Between 10% and 20% remaining is the sweet spot, but 5% or 25% isn't going to make a whole lot of difference. Then, I charge the battery to about 80-90% percent, but not completely fully. Obviously not all chargers/devices show a percentage, so in those cases I just charge to 100% and take the battery off the charger as soon as I see that it is done. I NEVER charge batteries overnight or unattended. If you do, you will notice that you batteries will not last very long and will eventually not hold a charge much sooner than you would expect. With this method you will extend the life of your batteries of all kinds (obviously I'm only referring to all kinds of -rechargeables-). However it most be noted that once every six months, or 10 charge cycles, I repeat the original battery-break in that I detailed in the beginning. This re-calibrates the battery and in a way, REMINDS it of its limits. Again, I know a lot of manufacturers claim "our batteries do not have a memory". I disagree as my personal experience proves otherwise. Obviously, your mileage may vary. I can't stress enough, that completely discharging any type of rechargeable battery to the point of it being dead; will literally reduce the life of the battery drastically UNLESS it is immediately charged, no matter what brand or type, or style they are. One last thing: I only charge my batteries with the device off, as the heat from charging and using the device is extreme. (ever try to charge your cell phone and play a game on it at the same time? Big no-no). Further, Try to charge your batteries in a cool environment around 50 degrees fahrenheit OR put a small fan in front of them while charging. As most people know, HEAT destroys batteries, and charging them makes them heat up considerably. The less you allow your battery to reach temperatures that are too hot/exceedingly warm, the longer they will last. The same goes for allowing your battery to die. The less you allow your batteries to die completely to the point of your device turning off, the longer they will last.

### ⭐⭐⭐⭐⭐ Works perfectly with my camera
*by D***Y on January 4, 2026*

Works perfectly with my camera, no issues at all

### ⭐⭐⭐⭐⭐ Great Batteries and Great Price
*by J***. on April 17, 2013*

If you're expecting Canon performance go spend 2-3 times the money on the Canon batteries. But I just did a wedding with these beauties and they are amazing. They charge up quick and seem to hold their charge rather well. Having just shot a wedding and bringing these along was brilliant. They last about 75% as long as the canon battery I use, however, for the price you can't beat it. I have only owned them for a couple weeks now, but they continue to impress me. We will see if other reviewers were more accurate and they die after a few months of use. But so far so good. Even if 1 of the batteries die it's still a great deal. I would caution against using these as your only option, strictly based on other reviewers problems and the fact that they aren't OFFICIAL canon batteries. With the wedding I did, I carried 2 spare canon batteries just in case, but only needed to use 1 of them because of these.
