I am selling Original Li-ion battery Panasonic NCR 18650 B 3400mAh PCB rechargeable battery, 3.7V, (Made in Japan), Year of manufacture 2023, Capacity 3330-3400 mAh, does not suffer from memory effect or self-discharge, discharge current up to 6.5A (protection more does not release), size 18.5x69mm PCB is protection against excessive discharge, excessive charging and excessive current. suitable for headlamps, led flashlights..., weight 49g, (unused) price for 1 pc - €7 6 or more pcs €6.75 box for two 18650 - €0.50 Price for postage: 1 pc battery +3, €50 (€2.20 payment on account) 2-9 batteries + €4 (€2.50 payment on account) the ad is valid until deleted. Some manufacturers even state 6800 mAh and more on their products, which far exceeds the parameters of li ion batteries. Well, the truth is that their capacity is at best 1200mAh. From my experience, batteries with a capacity of 4100 to 12000 mAh have at best 1200mAh, but more or less they have around 350-600mAh. These batteries weigh around 22-28 grams. or the voltage on the battery starts to drop sharply. Durability is questionable. And above all, batteries must weigh 44 grams or more (eg 2600-3400 mAh have 45-49g). Contact email: 2626@centrum.sk Phone: 0949369637
