Torches with built-in battery

Built-in battery

— a non-removable battery makes the housing more sealed and sturdier, and the flashlight lighter and more compact. Pros: better water protection (IPX ratings), a charge level indicator, fast charging, and sometimes a power bank mode. Cons: you can’t pop in a fresh cell on the go, and the cell inevitably wears out over charge cycles. Compared to replaceable batteries/AA, this kind of flashlight is more convenient for EDC, cycling, and camping where you have access to a power bank, but worse for long off-grid trips in freezing weather or expeditions. In practice: everyday pocket light, fixing a car in the driveway, an evening run. For longevity, it’s recommended to avoid draining to zero, store at 40–60%, and not charge in severe cold.
