Just my 2c but I have 15 year old Eneloops still going. They do have a lower voltage output which isn’t good for certain applications, but they are great for kids toys, remotes, flashlights/headlamps in my experience. Of the probably 60-70 I’ve bought, the only failures I’ve had are with the Pros, don’t waste money on those. I’ll have to check out Nitecore though.
