Warning:

Pay attention to these critical safety alerts to prevent fire, explosion, or severe chemical burns.

1. Do Not Recharge or Short-Circuit: This is a primary lithium cell; attempting to recharge, over-discharge, or short-circuit it presents a severe fire and explosion hazard.
2. Heat Restrictions: Never expose the battery to extreme heat above 100℃, and never attempt to dissect or incinerate it.
3. No Direct Soldering: Do not weld directly on the surface of the battery. Only use a battery pre-equipped with a guide lug or lead.
4. Do Not Mix Batteries: Do not mix old and new batteries, batteries of different models, or batteries from different manufacturers together in the same device.

Precautions:

Keep these handling and maintenance guidelines in mind for long-term operational safety and battery life.

1. Storage Conditions: Store unused batteries in a cool, dry, and well-ventilated area, preferably below 30℃ to maintain the <1% discharge rate.
2. Limit Operations: Operating the battery closely to its limit temperatures (-60℃ or +85℃) may lead to reduced capacity and a low voltage plateau reading.
3. Proper Disposal: When the battery reaches its end voltage, remove it from the instrument promptly and bury it deep underground or dispose of it strictly according to local hazardous waste regulations.
4. Short Circuit Prevention: Never carry loose batteries in a pocket or toolbox with metal objects like coins or keys that could bridge the terminals.
