Ultrafire 18650 Rechargeable 3.7V 3000mah Li-ion Battery Pair

Ultrafire 18650 3000mah 3.7V Rechargeable Lithium-ion Battery Pair + Free Battery Case 

Please note the listing price is for for a pair - 2 batteries
For every 2 batteries, we will add a 18650 battery plastic case (its a good quality plastic box for carrying batteries when not in use or extra batteries, each case will fit 2x18650 or 4xRCR123A). For example, If you order 4 batteries, we will add 2 cases in your order. 

Lightorati's Note: Ultrafire 18650 3000mah batteries are low end batteries. They do not come with any warranty. They are not as good as other battery options that we have but they just to the job. We have been using them since a while now and they are good for low end lights and rough usage like security, etc,. They do not have very long life like the standard 18650 batteries.  If you need great backup and full capacity, you can choose the UItrafire 2600mah Batteries which are full capacity. 

Buying: We would always advice you to buy batteries in sets of 2 and also use/charge in sets of 2 for optimal performance. Also please do not mix and match the sets. This way you can get the best battery life and performance. If one battery fails for any reason in a set of 2, buy another set and keep the single old battery as a spare. Practice this even for single battery lights. 

Charging: Initially do not use your batteries(rechargeable) uncharged even though the batteries come factory charged, they need 4-5 full charging cycles to give you the best performance. Meaning charge them to 100% when you receive them, let them discharge to about 90% when you start using, recharge 100% again, repeat this strictly atleast 4-5 times to make the most from the batteries. Quality batteries will survive a very long time for normal users - meaning till you forget when you bought them. Also make sure you are inserting the +/- sides in the right position, do that the wrong way and you are likely to blow the battery and charger. 

Usage: Handle batteries carefully, its easy to break batteries. We will check all batteries(for voltage condition) before sending them out to see if they are healthy or not. If they are dead on arrival, do let us know. But if you happen to drop them once from a considerable height like 3-4 feet on the floor, they will most likely die. So handle carefully. Once inside the light, the batteries are mostly safe. Most good lights protect the batteries will even if the light is dropped from a considerable height.
