3.7V 400mAh 701250 Lithium Battery

The 3.7V 400mAh 701250 Lithium Battery is a compact rechargeable cell designed for use in small electronic devices requiring a stable nominal voltage and moderate energy capacity. Its 3.7V nominal rating and 400mAh capacity provide a balance between runtime and size for portable applications where space is constrained.

This battery is suitable for low‑to‑moderate drain devices such as wearable electronics, small sensors, backup memory modules, compact medical instruments, remote controls, and other lightweight consumer electronics. It supports standard charging procedures for lithium‑ion/lithium‑polymer chemistries when used with an appropriate charger and charge management circuit that limits charge voltage and current to safe values.

Safety and handling: store the battery in a cool, dry place away from direct heat and sunlight. Do not expose the cell to fire, puncture, or mechanical shock. Use protective circuitry to prevent overcharge, overdischarge, and short circuits. Dispose of or recycle the battery according to local regulations for lithium batteries and follow manufacturer guidance for end‑of‑life handling.

Installation and operation: confirm compatibility with your device’s voltage and connector requirements before installation. Observe proper polarity when connecting and avoid mixing with cells of different types, capacities, or states of charge. If the battery shows signs of swelling, leakage, or elevated temperature during charge or discharge, discontinue use immediately and handle per safety guidance.
