【Frequently Asked Questions (FAQ)】
Q1: What is the difference between the five terminal options?
A1: Flat Top fits most modern devices. Button Top is for older spring-loaded devices. Nickel Tab is pre-welded for DIY pack assembly. Protected Top adds a safety circuit board (longer length). Pre-wired with Leads comes with red/black wires for direct replacement.
Q2: Do you offer wholesale/bulk discounts for 50+ pcs?
A2: Yes! Our pricing is designed to reward bulk buyers. Automatic tiered discounts apply at higher quantities (50, 80, and 100 pcs), making it cost-effective for businesses and project builders.
Q3: What is the continuous discharge rating?
A3: The official continuous discharge rating is 8A. Short-duration pulse discharges can reach up to 15A, but it is not designed for continuous 8A+ operation. For safety and longevity, we recommend staying within the 8A continuous limit.
Q4: Does this battery have a protection circuit (PCB/BMS) built-in?
A4: No, standard cells are unprotected. However, we offer a Protected Top variant that includes a built-in safety circuit for consumer electronics. If you are building a battery pack, we recommend using a separate BMS (Battery Management System).
Q5: How do I identify positive and negative terminals?
A5: 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.
