Here's a practical way to think about it: protections are 40% of the decision, battery brand/capacity 25%, indicator 15%, charging habits 10%, and removable vs. sealed 10%. That's not a scientific formula, but it reflects real risk.

You can trade off capacity for a better brand—a 500 mAh Samsung cell is safer than a 1000 mAh no-name. And don't skip protections for a sleeker design. A device that's pretty but has no overcharge protection is a ticking clock.

For most first-timers, a sealed device from a known brand with listed protections and a clear indicator is the sweet spot. If you're unsure, check the product page or ask in the community.
