Does Sony battery have not the limit of Rechargable times?

since I found my Canon camera's direction says that, there are around 200 times of rechagable limits for its Li-ion battery, it suggests that its user better use the % power to a low level before recharging, and if user does not do so, for example, recharge the battery when % power still has 50% unused, that is still counted as once of recharging, so that the battery will be dead sooner because of the 200 times rechargable limits. therefore, according the canon's direction, that seems its battery's longevity depends on the times of recharging.

that is so different from the info other people say here.
they suggest to rechage battery much earlier even the % charge at 40% or much higher,eg. 80% in order to protect the battery.

that is so different, I am really confused.
does sony battery have not the rechargable times limit?
or is there a totally diferent technololy between canon camera's battery and sony's?

thanks

 

As far as I know you have either misunderstood the Canon manual or the manual is wrong. For example: Using a Li-ion battery for 2% and then charging it 2% does not count as one cycle afaik.

Also I believe the cycle count is only an indication, it's not an exact measure for battery life time. Some batteries last 200 cycles, some 500.

Most guides agree that when using a Li-ion battery it's better to charge early and often, instead of waiting until it's almost empty.

PS. I'll move this to another forum where it will get more responses.

 

The cycles are cumulative % charged. So, say you charge it 50% one time, 25% a second time and 25% a third time, you would only have one full cycle and not three.

 

In answer to the OP's question, no all rechargeables have cycle limits.

The claims made by manufacturers often involve puffery and are unreliable. They have parameters and specs at their disposal. But, generally these manufacturers are not in the battery business. They're in the computer, camera, power tool, etc., biz and their batteries are buyouts. The recent battery recalls indicate this process since they invariably involve a specific battery supplier.

Look, aside from specs, batteries are like car tires or brake pads. Unless they're defective, a car manufacturer can't tell you how long they will last.
User feedback gives you a much better indication.
