Short answer: most people will not notice. Against the original at about 1040mAh the difference is negligible, and against 950mAh it is usually under fifteen grams, roughly a coin or two. Inside a body weighing more than four hundred grams that is under four percent, and it does not produce a clear “this got heavier” sensation during normal handling. What actually gets amplified is not absolute weight but the center of gravity and the way you hold the camera.
Let’s get the numbers straight
The original Canon LP-E17 weighs on the order of forty-five grams, on the light side for its class. Third-party high-capacity versions carry more cell material and therefore weigh a little more, but the spread is limited: from 750mAh to 1050mAh the difference for the whole battery is usually under fifteen grams, never a doubling.
A common misunderstanding is that a forty percent capacity increase means a forty percent weight increase. In practice most of a battery’s mass is the shell, the protection board, and the tabs; the cell is only part of it, and higher-capacity cells also tend to have better energy density. The weight penalty for added capacity is therefore non-linear and flattens out as you go up.
For any individual product the rated weight is whatever the maker publishes, and batches and protection-board designs will vary by a few grams. Thinking in terms of “under fifteen grams” is enough; there is no point chasing single digits.
Absolute weight matters less than proportion
The same battery feels entirely different depending on the body it goes into. The lighter the body, the larger the battery’s share and the more noticeable the shift in balance. A rough comparison by body weight follows.
| Body | Body weight, order of magnitude | Battery share | Perceived weight difference |
|---|---|---|---|
| EOS R50, M series | Just over 300g | About 15% | Fairly noticeable |
| EOS RP, R8, R10 | Just over 400g | About 10% | Mostly imperceptible |
| EOS 850D, 77D | Around 500g | Under 10% | Almost imperceptible |
| With a battery grip fitted | Clearly higher | Further diluted | Imperceptible |
The pattern is that lighter bodies and smaller lenses make the battery’s weight easier to feel. Fit a fast zoom and the body-plus-lens combination passes a kilogram, at which point fifteen grams is completely submerged. Any discussion of whether you can feel it has to start by naming the body and the lens.
Three situations that magnify the difference
Carrying the camera on a strap for hours. With the camera hanging from your neck, the strap carries everything, and any increment accumulates into soreness over a day. Fifteen grams is no longer fifteen grams; it is fifteen grams times a whole day. Hiking, street shooting, and trade shows are where weight savings pay off most clearly.
Shooting one-handed with the arm raised. With the arm extended, torque scales with arm length, and a battery sitting behind the body’s center of gravity produces a lever effect that tires the wrist sooner. On a small body like the 200D with a pancake lens, the difference is perceptible.
Portrait orientation. Rotating the camera moves your grip, so weight on the battery-compartment side sits farther from your support point and the body feels more lopsided. This is one reason many portrait shooters add a grip to bring the balance back.
Conversely, on a tripod, on a gimbal, or carried cross-body on a sling, the structure absorbs the battery weight almost entirely and the question is moot.
How to check for yourself instead of guessing
- Weigh both batteries on a kitchen scale and write down the grams. This establishes the real difference and keeps you from being led by the assumption that more capacity must mean more weight.
- Set the camera to the same state, fit the 950mAh, hold it out one-handed for twenty seconds, then repeat with the 1050mAh. Do it with your eyes closed to avoid priming yourself.
- Walk around for ten minutes with the camera on a strap and note whether the pressure points behind your neck and on your shoulder change. This is the closest test to real use.
- If you cannot tell the two apart either time, weight is not a selection criterion for your body and your shooting style, so choose on capacity and price.
The value of this routine is that it removes the psychological factor. People instinctively pay more attention to something new, more expensive, and higher-capacity; closing your eyes and fixing the duration cancels part of that bias.
One more thing to remember: weight can be managed with a strap, a different grip, or a lighter lens. Capacity cannot. A battery that runs out a few dozen frames early may cost you a shot. So the order of selection should be to decide the total runtime you need, then pick the lightest tier that meets it, rather than the other way around.
YO’s LP-E17 splits capacity into 750, 950, and 1050mAh. The 750 tier suits light travel where you shoot mostly stills and can recharge at the hotel that night; the 1050 suits long days away from power. For the exact body list, see the capacity and compatibility guide, or compare the 750mAh category with the 1050mAh category directly.
FAQ
Will 1050mAh make the camera heavier or more tiring to hold?
On bodies above four hundred grams, essentially no. The difference is under fifteen grams and sits near the center of gravity, so the lever arm is short. It may register on a body just over three hundred grams, when carrying on a strap, or when shooting one-handed with the arm raised.
Why doesn’t weight scale with capacity?
Because the shell, protection board, and tabs weigh the same regardless, and the cell is only part of the total. Higher-capacity cells also tend to have better energy density, so weight per unit of capacity falls; a forty percent capacity gain often brings only a ten to twenty percent weight gain.
Does the weight difference affect gimbal balancing?
Slightly. Gimbals are sensitive to balance, so if the rig feels nose- or tail-heavy after a swap, rebalance once. Fifteen grams normally falls within what the motors can compensate and will not prevent balancing.
For light travel, should I take the 750 or the 1050?
It depends on whether you can recharge that day. If you are back at the hotel and shooting at a moderate pace, the 750 is lighter; if you are out all day with a heavy shooting load and no fixed charging point, the 1050’s extra runtime is worth far more than fifteen grams. For a middle option, see the 950mAh category.
