18650 Batteries for Flashlights
The best part about 18650 batteries is that they're a rechargeable alternative to the standard store bought batteries we use in our flashlights.
That means that you won't need to buy boxes of AAA or AA batteries to power your flashlights and wasting lot of money in the process.
18650 batteries provide enough voltage to power your flashlights for hours and when the batteries are depleted, just charge it up and continue to use it.
18650 Batteries Guide
The 18650 batteries are a Lithium-Ion Battery that typically provides 3.7 volts 2600mAh of power.
They're compatible with most household electronic devices so they're easily interchangeable between devices when batteries run out of power.
Storing 18650 Batteries
When using, handling, and or storing 18650 lithium ion batteries, there are a number of safety measures that should always be followed in general and according to the manufactures instructions.
- 18650 batteries should be stored in temperatures between 32℉-110℉ for best results. Heat and cold temps will cause batteries to age quicker.
- Charging the batteries requires the right equipment. Only use the manufacturer recommended charger and the charging rate. They build chargers with proper protection circuitry to protect the battery.
- Do not let the battery deplete down to 0%. This will increase the stress put on the battery and decrease the life expectancy. Keep it charged according to manufactures recommendation.
If not stored properly, the batteries could potentially explode and catch on fire! Store them according to the manufactures recommendations.

Alternative to Lithium Ion Batteries
The safer alternative to lithium ion batteries is the lithium polymer battery.
What makes this battery safer is that it does not use liquid chemicals, but rather a more solid alternative.
However, availably of these batteries for everyday household devices such as flashlight is limited.
These batteries are typically reserved for use in compact electronic devices such as cellphones.
