FAQ
Q1: What is the difference between Button Top and Flat Top?
A: Flat Top has a flat positive terminal, compatible with most modern devices (flashlights, DIY packs). Button Top has a raised positive terminal (like a standard AA battery), required for older devices and certain battery holders with spring-loaded contacts. Please select your desired version when placing your order.
Q2: Why should I buy a 50-pack instead of single cells?
A: Buying a 50-pack offers significant cost savings compared to purchasing individual cells. It also ensures batch-matched consistency across all cells, which is critical for building battery packs and ensuring uniform performance in mass-produced devices.
Q3: What devices is this battery suitable for?
A: This 1200mAh battery is ideal for low to medium-drain devices such as solar lights, headlamps, remote controls, mini fans, small toys, and clocks. It is not recommended for high-power applications like vaping, power tools, or high-lumen flashlights.
Q4: 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. This provides maximum flexibility for use in devices with built-in protection.
Q5: How many times can this battery be recharged?
A: This battery can be recharged approximately 500 times, depending on usage and charging habits. Proper care (using a quality charger, avoiding full discharge, and storing at moderate temperatures) will extend its lifespan.
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 do I identify positive and negative terminals?
A: The flat top (or the raised button on button top version) is the Positive (+) terminal. The bottom (the side with the shiny metal casing and a slight indentation) is the Negative (-) terminal.
Q8: How should I store the 50-pack when not in use?
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.
