Got this two months ago when it was this price, very nice battery. Been trying to use it every day since lmao. Will try to cycle it at least 500x, most standard Lion chemistries will show extremely noticeable degradation by that point.

Let's see how it performs long term. The only issue is that it has no percentage indicator. The 4 dots are very outdated

Just a heads up if you're clueless like me, this won't charge when you use bands that can't be split in half, like the Sport Loop, Solo Loops, Milanese Loop, etc

can you not flip the sports loop inside out?

It has been this price since at least July 2025. Not a slick deal.

This isn't necessarily a slick deal as compared to previous prices but it's actually a good value over all.

Correct.

However, this site isn't called: standard pricing with good value.

This item is standard price at $18.

The mfg plays pricing games with coupons and promotions to make this look like a really good deal.

It shouldn't be posted, here, again unless the price is below $18.

Getting posted here repeatedly for $18 is just product promotion.
