Looking for the cheapest 18650 LED light I can find. We are standardizing on them for our heavy use lights here.... Why do I want cheap? OK you busted me. The real reason is that my 3 year old daughter has recently become obsessed with flashlights and has blasted through a small mountain of AAs in our cheapo LED lights. She's getting upgraded to rechargeable and all my rechargeable flashlights use 18650s.

Amazon has a bunch under $10, but battery and charger are extra.

AA Eneloops
18650 are too dangerous for kids. Especially in a high power light. Eneloops won't explode when discharged too fast. |

I don't see many 18650 lights that put out less than 500 lumens on the top end. Lots of them are close to 1000. At that level the light puts out a huge amount of heat. Enough to burn someone. Unprotected cells would be extremely bad for a kid. You would ruin them as soon as they were over discharged the first time, if it didn't burn. |

Can you charge them and leave them charged for long periods (6mo-year)? Can they be substituted for any device that would normally hold the particular size? Are they damaged by leaving them discharged for a prolonged period? Any catches other than cost? Also I appreciate the replies. I honestly had not thought about the safety aspects of using the lithium. She likes to turn the light on and then forget about it until it dies which I could see being a fire hazard if she dropped it into her toy box or something and it overheated. |

I don't know about leaving them discharged but they are famous for holding a charge over years. They have very low self discharge rates. Use them in place of any AA battery. |

Cause 3: Over-discharged.
Applications without over-discharge preventing device can cause batteries to over-discharge. For example, use low current draw LED light until battery runs out, it cause over-discharge and later cannot charge the battery correctly. Recharging battery 2-3 times solves this problem but if the problem still persists, It is considered battery’ s life span has ended and please stop using. Continuous over-discharging causes damage to the batteries. We recommend to recharge the battery, once luminous energy become low or battery energy become low during using LED light they will maintain 75-80% of charge after 3 years if no use. http://panasonic.net/energy/eneloop/pdf/eneloop_handbook.pdf |

for her just getting the cheapest nicad rechargeables you can find might be best. they are not that expensive compared to alkalines and if you get 20 charges out of them before she kills them you come out ahead.
would also be a good time to teach her about responsibility such as turning thigs off properly and taking care of it. |

With multiple cells and discharging to zero volts, one of the cells with go to zero first and other(s) will reverse charge that cell as the load current runs thru it. This will damage the zero volt cell. There is no reason to discharge a Ni cell much below 1.0v. At this point something like 95% of stored energy has been used. Anything further is waste of time and risks damaging the cell if used in a series application. |

Most of my cheap 18650 lights get pretty hot.
I usually give my kids some AA or AAA lights that they can play with. Go to lowes and buy a mega pack of their off brand AA or AAA batteries. Those last a LONG time. Plus, I find my rechargable batteries to be too expensive for the kids, as they have a tendency to lose the lights.
