3 FAQs about 10440 solar container lithium battery pack
What is a 10440 lithium ion battery?
High-Capacity Design: 10440 lithium-ion batteries, each with 350mAh capacity, in a compact AAA-sized form factor (10mm x 44mm) but with a higher 3.7V output. High-Voltage Compatibility: These 3.7V batteries are specifically for devices that require high-voltage 10440 cells and are not compatible with standard AAA devices.
What is the difference between protected & unprotected 10440 lithium batteries?
Protected 10440 lithium batteries include a built-in circuit board that prevents overcharging, over-discharging, and short-circuiting. These are ideal for beginners or anyone using them in sensitive or expensive devices. Unprotected 10440 batteries, on the other hand, lack this safety layer.
Is a 10440 a good battery?
Despite its small size, the 10440 lithium battery packs an impressive punch when it comes to capacity. Most high-quality models offer between 300mAh and 600mAh of energy. That’s lower than the capacity of AA or even some AAA batteries, but the tradeoff is a much higher energy-to-size ratio and voltage.
