Canon 30d and Battery Life

Recommended Posts

I have the Canon battery and a Stirling Tech 1800ma battery. Probley only about 30 hours total on each. With the Tamron 28-75 lens, the batteries would last for several hours of "continuous" use. Maybe the Canon 100-400 IS lens is a battery blaster...it seems like I can only get about an hour or less of "continuous" use with that lens (I'm certainly not complaining though cool.gif). Is this normal?

Swimmer, that's not normal at all. IS lenses take about 30 percent more battery power, but I shoot the 20D with two batteries in the battery grip all day long with the 100-400L IS and often don't need to change batteries at all. If, however, you're staying focused on a subject for a long time with the IS engaged, you'll use up battery a lot faster than if you don't keep the IS going. Maybe that's what you mean by "continuous use." There are times when a person has to lock focus and compose the image and keep the lens ready and IS on in order to wait out a bird or animal to turn just the way you want it, but unless that's the case, I don't keep the shutter button depressed half way for any length of time at all between shots.

IF you were engaging the image stabilization a lot and IF your batteries were short of full charge already and IF it was quite cold out, which drains batteries, then with all those factors combined I could see the scenario you presented. Other than that, I don't know what it might be.

I'm pretty obsessive about my batteries. Even if I only shoot for half an hour, I pull them from the camera when I get home and charge them fully. Many types of batteries, if run down and not charged back all the way, will never achieve their maximum charge again, and I've never wanted to take that chance.

Since the SterlingTek batteries are so inexpensive, Swimmer, it might not be a bad idea to plop down the extra $30 for the set of two and make sure they're totally charged after you get them and then see how things go. Totally flat batteries for the 20D/30D will recharge completely in 3 hours on the Canon chargers. I always leave them in longer, just to be sure, which doesn't hurt them.

    • I bought my first boat last September and I have a question about weight distribution. I was warned that it's a heavy boat by the seller, he called it a tank. In a good way. It's very sturdy in big water. So that's cool, but the first time I had a third adult hop in, the boat basically turned into a barge and just plowed water. With two "hefty" adults, gear and a cooler I have no complaints. It gets up on a plane no problem and scoots along just like you'd expect it to. Adding a third, non-hefty adult and gear was too much for it though. It couldn't get up on plane and the front end just plowed water.    It has a 24v trolling motor on the bow. The two marine 12v batteries for the trolling motor are also in the front, not all the way in front, but close. A buddy said he'd try moving the batteries to the rear. So what I'm wondering is, how much weight can you put in the rear of these boats and is this a good idea? Assuming they'd even physically fit. The main battery is already in the rear.    As a comparison, I have a 17' with a 60 HP 2 stroke and my dad has a 16' with a 50 HP 4 stroke, both tillers. My dad's boat slows down a bit with all of us in it, but easily gets up on plane and operates normally. His boat is a little more on the bare bones side and his motor is a good 10 years newer, but otherwise it's basically the same setup, but smaller, and it moves all of us around very well. This makes me wonder if my boat is or should be capable of more.    I also thought of the possibility that my old 1997 2 stroke is just tired (is that a thing?), but it seems to run very well. I also took it to what I think is a good repair shop and they assured me that I have the correct prop.    Here's all the info I can think of and a few pics.   1996 Alumacraft Competitor 170 1997 Mercury 60 HP 2 Stroke (60 HP is the max HP rating) 85" Beam (or close to that, can't remember for sure)   Try moving the batteries? Save up for a new motor? Or that's just the way it's going to be? Any advice from the community would be very much appreciated!  
    • Hello from the NW Angle! Areas of slush on trails in Minnesota are refreezing overnight and are still in good condition if well-traveled.  Walleye action is getting better every day, with mornings and late evening being best.  Rippin’ raps and buckshots are enticing violent strikes; 18-22 ft of water is key. Big northern pike are hitting jiggin’ spoons and tip ups with large baits. Anglers venturing into Canada continue to find schooled Crappies and big walleye deeper into 30+ feet. A slow presentation is most effective for catching crappies.  Until next week, Sunset Lodge
    • Yesterday the exterior lights under the side mirrors, all pick up bed lights and the tailgate light would intermittently turn on and go off.  I checked to make sure all doors were shut and checked all the lighting options in the vehicle.  The light issue killed my battery and it is very slow to take a charge.  Has anyone seen something like this?  I checked on line and didn't see any mention of an issue like this.   My truck is a 2017 Ford F150 Lariat with the 3.5 ecoboost.  I called the dealership and they said they could get it in the week of April 22.  A lot of good that is going to do me when the vehicle is dead.
    • Thanks guys, looks like I need to give it a try!
    • Last summer my son caught a 30.5" walleye on a local lake. It was a hot day so we put it back pretty quickly. We decided to surprise him with a Replica. Fiber Tech out of Nisswa did an amazing job! Only took 6 weeks once I made the call. I will use them again.
    • Parise and Ek hurt, slowly fading in the standings and in the midst of a rebuild, the golf clubs aren't out yet but the boys have been thinking about getting them out and dusting them off.
