Question by Mentalbox: 1.2V AA batteries on Flashlight that specifies 1.5v AA batteries?
I’ve ordered a Fenix LD20 flashlight. But as specified on amazon.com, “Uses two 1.5V AA (Alkaline, Ni-MH, Lithium ) batteries”.
I need/want rechargeable AA batteries, preferably that can be recharged with a USB adapter.
So what I have looked up is, amazon-title: “Sanyo Eneloop 2-AA NiMH Pre-Charged Rechargeable Batteries with USB Charger”. From what I understand, these are 1.2V. Will my flashlight work and omit a sufficient amount of light (i.e. not less than 80% of normal) anyway with these batteries?
Note: I am Norwegian – non-US, so whatever optional item you consider better must be available to me via eBay or other services with low shipping (Amazon has changed to extremely expensive, 100$ ish shipping to Norway). And again: remember I need the USB charging option (I will be hiking for a long time, and I have an external battery with USB port + solar panel)

Most primary (non-rechargeable) cells are 1.5 doesn’t matter if they’re AAA, AA, C, D.
“Most” rechargeables are 1.2. There is a slight difference in diameter usually (larger) – this normally has no effect, but I have one flashlight that rechargeables get stuck in – almost impossible to get out – don’t force rechargeables into anything.
Most anything a non-rechargeable works for a rechargeable will too. They have a shorter run time than a non-rechargeable. I don’t see any difference in the brightness although common sense would tell you there should be some.
I have 100s of rechargeables that I use for everything from power tools to flashlights, guitar tuner to digital voice recorders, digital cameras to portable jobsite radios, and my mp3 player.
I do suggest you get an extra set of batteries – and yes any rechargeable battery will charge on any charger designed to recharge that model (AAA, AA, C, D) and chemical makeup battery – you must use a lithium battery charger for lithium batteries. My lithium chargers will charge NiMh and NiCad (don’t use NiCad if you can avoid it – I have to for some power tools) – I’m not sure if all will or not – they’re a bit hard to come by as are the batteries. A NiNhd charger will also charge NiCads but it will not charge Lithiums.
Lithiums are much better (longer runtime, longer shelf life) than Nickel Metal Hydride and are coming into the market place. I have a rechargeable lithium battery pack for a camera that is really just two AAs – but they cannot be taken apart. I also have some rechargeable CR123 lithium. So far they’re hard to find and expensive (but still worth it).
I don’t understand the “whatever optional item you consider better” thing – sorry. You stated that you “have an external battery with USB port and solar panel” – don’t know what optional item you would need besides that.
You can order rechargeables/chargers off of eBay. Most any brand. There are also many cheap(er) Chinese made ones – I have found them to be good batteries but it takes a while to get them here (U.S.). Shipping was very reasonable and there were no customs charges (sent as “gift”).
