Product Description
This is a high-performance Lithium Iron Phosphate (LiFePO4) rechargeable battery in the standard 14500 size (AA battery size). With a nominal voltage of 3.2V and a typical capacity of 600mAh, it delivers reliable and long-lasting power for your compact electronic devices.
Renowned for its superior safety, exceptional cycle life (up to 2000+ cycles), and excellent thermal stability, LiFePO4 chemistry makes this battery an ideal upgrade replacement for AA-sized Ni-MH/Ni-Cd batteries. It is widely used in emergency lighting, solar garden lights, smart door locks, RC models, vape devices, and various DIY projects and emergency backup power applications.
1. Unmatched Safety: Emergency lights are often installed in public spaces (hospitals, shopping malls, subway stations) where safety is paramount. LFP batteries have an intrinsic chemical structure that resists thermal runaway—even under extreme conditions (e.g., overcharging, short-circuiting, or physical impact), they rarely catch fire or explode. This eliminates the safety hazards associated with other battery types (e.g., lead-acid batteries, which may leak acid, or LiCoO₂ batteries, which are prone to thermal runaway).
2. Long Cycle Life: High-quality LiFePO₄ batteries offer a very long cycle life. Well-maintained cells can achieve over 2,000 cycles (to 80% of initial capacity). This translates to over 4 years of service with one cycle per day, making them cost-effective in the long run.
3. Stable Discharge Performance: During power outages, emergency lights require consistent brightness to guide evacuation. LFP batteries maintain a flat discharge voltage curve (typically 3.2V per cell) throughout most of their discharge cycle, ensuring the light output remains stable and does not dim prematurely. In contrast, lead-acid batteries experience significant voltage drop as they discharge, leading to reduced brightness in the later stages.
4. Wide Temperature Adaptability: Emergency lights may operate in harsh environments, from cold warehouses (-20°C) to hot industrial facilities (60°C). LFP batteries perform reliably within a temperature range of -20°C to 60°C, whereas lead-acid batteries often lose capacity in low temperatures and degrade quickly in high temperatures.
5. Environmental protection and ease of use: They are free of heavy metals like cobalt and lead, non-toxic and non-polluting, making them more environmentally friendly. They have no memory effect, allowing convenient recharging at any time without needing a full discharge.
● Do not short-circuit, crush, or puncture the battery.
● Use a compatible charger to avoid overcharge or over-discharge.
● Do not use or store the cell above 70°C or below -20°C.
● Keep away from fire or water.
● Check the cell for damage or swelling before use.
