I use plenty of rechargeable batteries, but I also use disposables. Disposable batteries hold significantly more charge and sometimes that matters. For instance my smart lock if I fill with rechargeables I find myself having to call a locksmith. I think that might be not only due to the lower capacity but that it holds closer to voltage until completely drained so it prevents the lock from giving me adequate warning. I also have a property that’s an AirBnB and I’m sure those tenants are animals, so I leave the disposables for things like remotes. They would just dispose of rechargeables if I let them.

> Disposable batteries hold significantly more charge and sometimes that matters. Not really true but also not wrong. Disposable batteries tend to be on par with rechargeable when it comes to charge. Disposable AA 2850mAh [1] Rechargeable 2000mAh [2] What you are (likely) experiencing is that rechargeable batteries tend to have much higher self discharge rates than disposables. The end result is the rechargeable feel like they have less capacity as they seem to last for a shorter period of time. Further, the lower voltage tends to also push you to need to recharge them because your devices fail to work at the lower voltages. The dastardly part of rechargeable is you can get like 3500mAh AA but you shouldn't because those tend to have absurdly high self discharge rates. (AFAIK) The enloop batteries tend to be the best when it comes to self discharge, but at the cost of lower total capacity.

  Ummm 2850 is significantly higher than 2000. 40% is significant.
