LiitoKala Lii-36S 18650 3600 mAh Battery — Overview
The LiitoKala Lii-36S is a rechargeable lithium-ion (Li-ion) 18650 battery with a nominal capacity of 3600 mAh. Manufacturer: Liitokala. This power cell provides a stable nominal voltage of 3.7 V, reaches 4.2 V when fully charged, and can be discharged down to 2.5 V. The battery's lifespan is at least 1000 full charge and discharge cycles, making it a reliable choice for long-term use.
Low internal resistance — less than 30 mΩ — contributes to efficient energy delivery without excessive losses, which is especially important when powering devices with peak currents. The LiitoKala Lii-36S design is reinforced with an explosion-proof valve to enhance operational safety in various conditions.
The battery is suitable for powering a wide range of devices: audio systems, dashcams, household massagers, cosmetic devices, and other gadgets that use the 18650 format. The model performs well under typical operating conditions and ensures stable operation under prolonged loads.
Operating Recommendations: Use a certified charger designed for lithium batteries to avoid overheating and over-discharge. It is recommended to recharge when the charge level drops to 10–20% to maintain battery life. At low temperatures, a temporary decrease in capacity is possible — this is normal; recovery of performance usually occurs after warming up for approximately 1 hour.
