FAQ
Q1: What is the difference between Flat Top, Button Top, and Nickel Tab?
A:
-
Flat Top has a flat positive terminal, compatible with most modern devices (flashlights, power tools).
-
Button Top has a raised positive terminal (like a standard AA battery), required for older devices and certain battery holders with spring-loaded contacts.
-
Nickel Tab comes with nickel strips pre-welded to the positive and negative terminals. This is ideal for DIY battery pack building – no soldering required, just spot welding or direct connection.
Q2: What is the capacity of this battery?
A: This battery has a 2000mAh capacity (minimum 1900mAh). It prioritizes high power output over runtime, making it ideal for devices that need short bursts of intense power.
Q3: What does 20A mean?
A: 20A refers to the maximum continuous discharge current of this battery. This means it can safely deliver up to 20 amps of power continuously. This makes it suitable for demanding applications like mechanical mods and power tools. However, its lower capacity (2000mAh) means it won't last as long as higher-capacity cells.
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 1000+ 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 3.6V/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 this battery 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.
