Its 3500mAh capacity supports runtimes of up to 13 hours in the MegaStream, and it recharges via USB-C in or outside the flashlight without a separate smart charger.\u003c\/p\u003e\n\n\u003ch2\u003eExtended Runtime When It Counts\u003c\/h2\u003e\n\u003cp\u003eThe SL-B34's 3500mAh lithium-ion cell delivers up to 13 hours of runtime in the MegaStream flashlight. For professionals who carry a light through a full shift, that capacity means fewer interruptions and less time managing power mid-task. Keeping a charged spare on hand extends operational readiness without requiring a dedicated charging station.\u003c\/p\u003e\n\n\u003ch2\u003eCharge Anywhere, No Extra Hardware\u003c\/h2\u003e\n\u003cp\u003eThe SL-B34 charges through a USB-C port, so any USB-C cable and a standard wall adapter, car charger, or power bank will do the job. Charging works whether the battery is seated inside the MegaStream or removed, with no proprietary smart charger required. A built-in indicator light shines red while charging and green when the charge is complete, removing any guesswork about readiness.\u003c\/p\u003e\n\n\u003ch2\u003eKnow Your Power Level at a Glance\u003c\/h2\u003e\n\u003cp\u003eA built-in battery indicator shows remaining power, so there is no need to guess whether the pack is ready before heading out.
