How to Choose TYPE-C Rechargeable 1.5V Batteries: Match Size (1/2/3/4) to Capacity & Use Cases
Upgrade your home battery routine with TYPE-C rechargeable 1.5V cells. Learn how to pick the right size (1/2/3/4) by capacity and everyday scenarios, plus quick guidance on charge indicators and safe handling.
Why size and capacity matter for 1.5V devices
Even when the voltage is 1.5V, different battery sizes deliver different runtime. This product line offers 1/2/3/4 sizes with distinct capacities, helping you match batteries to how often and how heavily your devices use power.
1/2/3/4 size guide with practical mapping
Use the capacity table to decide: 1號 (12000mWh) for longer runtime needs, 2號 (5000mWh) for general daily use, 3號 (2600mWh) for AA-class devices, and 4號 (750mWh) for AAA-class devices. This reduces overbuying and improves convenience.
Charge indicator and safety checklist
During charging, the indicator blinks green; when fully charged it stays green. For safety, avoid short-circuiting by keeping terminals from touching, do not charge inside devices, and stop using batteries if leakage or deformation occurs.
Quick FAQ before you buy
Common questions include how to read the LED, which size corresponds to AA/AAA, whether bigger capacity is always better, and how rechargeable cycles depend on proper usage.
