FAQ
Q1: What is the capacity of this battery?
A: This battery has a 3500mAh capacity (minimum 3400mAh), offering significantly longer runtime than standard 2600mAh batteries. This makes it ideal for devices that need to run for extended periods without recharging.
Q2: What does 10A mean?
A: 10A refers to the maximum continuous discharge current of this battery. This means it can safely deliver up to 10 amps of power continuously. This makes it suitable for medium-drain devices like flashlights, headlamps, and solar lights, but not recommended for high-power applications like vaping or heavy power tools.
Q3: What is the advantage of buying the 2-Pack?
A: The 2-Pack offers two main advantages: convenience and value. You get two matched cells in one package, saving time and effort. You also get better value compared to buying two single cells separately.
Q4: How long will these batteries last?
A: With proper care, these batteries can be recharged over 500 times. For a typical user, this means several years of reliable service. The 3500mAh capacity also provides extended runtime between charges.
Q5: Is this battery protected or unprotected?
A: This is an unprotected cell. It relies on your device's built-in BMS (Battery Management System) or protection circuit to handle overcharge, over-discharge, and short-circuit protection. Most devices with 18650 compatibility have built-in protection.
Q6: What charger should I use?
A: Use a dedicated intelligent Li-Ion charger designed for 3.7V/4.2V cells. Do not use universal chargers designed for NiMH batteries. Look for chargers with overcharge protection and temperature monitoring features.
Q7: How should I store these batteries?
A: Store at a partial charge (around 40-60% capacity) in a cool, dry place away from direct sunlight and extreme temperatures. Do not store fully charged or fully depleted for extended periods.

One cell gave 3380mAh, the other 3410mAh. Still very high, but not quite 3500. Performance is good.
My Zebralight SC64 now runs for ages on these 3500mAh cells. 10A is plenty for up to 1000 lumens. Highly recommended.
I replaced the cells in my smart doorbell chime box with these, no more frequent charging. 3500mAh is a huge upgrade.
Arrived well-packed, charged to 3.5V. Capacity meets expectations. Used in my LED lantern, lasts a full night.
Using in a WiFi door sensor, this 18650 lasts months. 10A is unnecessary but capacity is brilliant. EVE quality.
