The Streamlight 78105 rechargeable SL-B26 Li-Ion battery pack is the power solution serious users need for their Stinger 2020 flashlight. A pair of 2600mAh batteries keeps your light ready to go during extended field work, tactical operations, or emergency response—and this bundle includes a charger and micro USB cord so you're fully equipped from day one. Li-Ion chemistry means fast charging, longer lifespan, and no memory effect, making these batteries far more practical than disposables for anyone who counts on their light.
Stinger 2020 owners already know their flashlight delivers on performance; the right battery keeps that promise intact. At 3.7 volts, these cells deliver the voltage spec your light expects, with enough capacity to handle extended runtime without dropping your brightness when you need it most. Having a pair on rotation means one charges while the other works, so you're never waiting around for power. The included micro USB charger is the same standard connector found on phones and most modern gear, so travel and field charging are straightforward.
Whether you're running a Stinger 2020 professionally, in the field, or for emergency backup, this two-pack with charger removes friction from your power management. Keep one set in your pack, one at the ready, and you've covered your bases without fuss.
