18650 High Drain Rechargeable Batteries

I'm very happy with these 18650 batteries.

I use this caddy to hold 18650 batteries. This sturdy plastic caddy keeps these high-amperage batteries apart from each other and also protects against other metal objects contacting the terminals. The batteries are recessed and securely held when placed into the caddy yet can be removed with just one hand. Very handy and well thought-out.

Nitecore 18650 Li-Ion Rechargeable Battery is a great source of stored energy. Being rechargeable makes this battery cost effective. This Nitecore Li-Ion battery has demonstrated its dependability in a flashlight over a period of seven hours of intermittent use. Great product!

I have several 3rd party batteries and they drain way faster than the Sony. I will only use these batteries going forward.

take a bit of calibrating - it reaches further and less drain on flash batteries.

Quality rechargeable batteries.

Great so far... A little weird behaviour with AAA and AA batteries but perfect with 18650 batteries.

These are the best high-current non-rechargeable AA batteries on the market (effective capacity of up to 2x that of recheargeable Eneloops). B&H had the best price, and delivered them fresh (they were made in August 2011 and guaranteed to last till year 2026 in storage).

This was definitely a lot smaller than I thought it would be but it's honestly not terrible. Price could be lowered for how small this flash light is. $39.99 does seem pretty high for a flashlight that's only 3 5/8" long in my opinion. But it is pretty bright and definitely good quality. Pros: - Really bright for it's size - Has three settings of brightness (low. medium, high) - Compact for traveling - Has the flood and focus feature - Has a decent battery life with the rechargeable battery that comes with it Cons: - You have to click it on and off to cycle through the settings and it wont stay on the setting that was last used (defaults to the medium setting) - No external port for charging so you have to plug into the port of the battery or replace batteries if you are not using the rechargeable batteries.

Very high-quality headlamp. Really like the fact that it is rechargeable as I throw away a lot of batteries with my old lamp. I also have the H15R and like the tighter focus on the H7R Be nice if Ledlenser would make a bicycle light.
