What size batteries does GearLight S1000 use?

The GearLight S1000 uses either AA batteries or an 18650 rechargeable lithium-ion battery. This flexibility allows it to cater to a wider audience, as AA batteries are widely available and easy to replace. However, the 18650 option can provide longer run times, especially for those who use the flashlight frequently. To maximize performance, consider opting for high-capacity rechargeable batteries if you choose the 18650 route. A Pro Tip is to keep a set of spare batteries on hand, especially if you plan to use the flashlight for extended periods or in emergency situations. While the availability of these batteries is generally good, it's always wise to stock up, particularly with rare or specialized batteries.
