Apple Watch Battery Charge Cycles

Seem to take and hold a charge. It will take several cycles to see how they hold up.

After 4 years, thousands of photos and hundreds of charge - discharge cycles my original NB-13L battery was declining in capacity and needed replaced. Maybe I could have saved by buying a 3rd party battery but I figured the premium price over 4 years comes to about $5 per year and I can afford that for the premium Canon brand.

This battery has worked very well over a number of charge cycles. It is less expensive than the Canon branded battery and seems to have similar performance

Have used this battery pack over a few charge; use until near depleted and recharge cycles, and have found it to be as good as the original battery shipped with my X-T2. Mirrorless cameras put a high drain on the batteries since their rear display, imaging sensor and eye-level display together consume lots of power. Since this is the case, I want to carry two batteries. Personally, I rather pay the premium price for a manufacturer battery and the quality control that comes with it. This battery is worth the price. However, that's just my opinion, as always YMMV.

I've been using Eneloop batteries at work and home for years, with dozens of batteries in service, and they always get the job done. As far as meeting advertised claims: They do indeed hold charge as advertised (never tried for 10 years, but if I charge a batch up they will still be in good shape after sitting around for months). I periodically run batteries through a 3-cycle refresh to confirm they're still healthy, and I have only ever had one battery out of several dozen in heavy use fail after a year or two of use (by fail I mean it was only 60-70% of the original capacity without having gone through a large number of charge cycles). The up to 800mAh is unfortunately the same as other Ni-MH batteries, which is to say probably only accurate if you bleed the battery absolutely dead at a very low discharge rate. On my tester, being drained at 200mA (similar to a moderate-drain application), they clock in at about 730mAh when new, which is about the same 90% of rated I've come to expect. On the plus side, after at least a couple hundred charge cycles, they still measure at essentially the same capacity as when new.

what's that saying? you get what you pay for. I had a couple aftermarket batteries I used with my A6300 and after about 5 charge cycles, they started showing a severe drop off in capacity. Yet the original Sony battery is still chugging out better than 90% capacity after 100+ cycles. So I recommend a bit more coin for a reliable battery that will not let you down.

It fits fine, even in my underwater housing. I have only had the battery a short, so no idea how many charge cycles it will hold, but I bought a spare at the same time.
