At higher ambient temperatures, the rating decreases: 10A (35–45°C) and 7.5A (45–60°C).

Ultra-high capacity cells like the M58T are not designed for the high current demands of sub-ohm vaping.

Fast charging at 2.7A (4.20V cut-off) or 5A (4.0V cut-off) can reduce charge time significantly. For longest cycle life, stay at or below 1.12A.\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003eQ: Are these protected cells?\u003c\/strong\u003e\u003cbr\u003eA: No, these are unprotected flat-top cells.

The 5800mAh capacity will provide significantly longer runtime than standard 5000mAh cells.\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003eQ: What is the cycle life of the M58T?\u003c\/strong\u003e\u003cbr\u003eA: Under normal usage with standard charging (1.12A) and moderate discharge, the M58T retains ≥80% of its original capacity after 500 cycles. At higher discharge currents (7.5A), cycle life may be shorter.\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003eQ: Does the M58T work in cold weather?\u003c\/strong\u003e\u003cbr\u003eA: Yes, the M58T can discharge down to -20°C, though capacity will be reduced. For best performance in cold weather, keep the battery pack above 0°C when possible.\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003eQ: How does the M58T compare to other high-capacity 21700 cells?\u003c\/strong\u003e\u003cbr\u003eA: Independent testing shows the M58T is a very good performer, equal to the Vapcell F58\/F60\/F63, and offers longer runtimes than the Lishen LR2170SK at moderate discharge rates (5A and 10A).
