Note: I'm not a flashlight geek, just lurking - but I feel compelled to point out some things from that perspective...

You're talking about an AAA pen light (1 or 2 AAAs, right?) so there's pretty close to zero chance of it being what anyone would consider "high performance." If you want maximal light output you'd be way way way better off picking a different type of light with a more robust power source.

But for AAAs it's really not too hard : Alkalines for cheap, LSD NiMh for a rechargeable option, or Lithium for special use cases. Ignore "Heavy Duty" batteries except maybe in desperation or for nostalgia. There really aren't other options readily available for AAAs.

FWIW, I'm currently using a Coast G19 which I like a lot compared to the generic crap I've previously used. It's bright enough and well focused (almost zero spill), tough enough to get stepped on etc. - and I've even managed to get it back from everyone who has borrowed it. (so far)

Battery-wise, I took a coupon to the local Harbor Freight store and picked up a pack of $3.99/24 AAA alkalines. I used two in a wireless mouse. When it reported a low battery level I took them out and put one in my light. It's been working for occasional use well over 6 months, with no signs of giving up yet. I think it'll be hard to beat that. (except maybe for using the 9Volts I remove annually from smoke detectors with one of these

If I was in very-low-temp conditions, cared a lot about saving weight, or couldn't easily replace the battery and needed high reliability (long wilderness trips?) I'd use a disposable lithium AAA - like these from Energizer … at about 10x the cost of alkalines.

Using NiMh, I've had "mixed" experience with performance, but that's probably because I was using super-cheap lights. If my light happens to disappear after being "borrowed" I'd just as soon not lose a good battery too. But if I used my light super frequently, and wanted to give two shits about the environment, they'd probably be a decent choice.

Anyway - hope that helps some.

The AAA is the better option. You still get pretty much the same battery life and you save weight.

Here’s what I believe are the lightest AAAs you can buy and here’s the adapters you’ll need to use them. I like that kit because it comes with 12 adapters (so you can also switch things like your TV remotes and household wall clocks over to cheap AAA and save some cash in the long run) and also the storage case that’s included is actually pretty nice.

If you’re in the US and you’re interested in swapping the shell over to a 3D printed version with honeycomb holes then let me know and I’ll share the link where you can buy them already printed.

FIX FOR HEAVY WEIGHTED PEN: =============================

Since most of the pen weight is comming from the AAA battery which I'm assuming is an alkaline cell, you probably can reduce pen weight by getting a lighter Lithium Ion battery.

There are two assumptions that I'm making here: pen battery is regular alkaline rechargeable and the voltage is 1.5v. If I'm wrong and it's actually Lithium, voltage could be as high as 3.4V. Someone with a multimeter can check this out. If I buy pad, I'll update.

So, supposing my assumptions are correct, you need to make sure that you have the right voltage before looking for lighter battery as lithium AAA comes in 1.5 and 3.4v. You also need to make sure the lithium AAA is 44mm high because.

Looking into it, I found typical LiIon weight was about 33% to 66% of the weight of the typical NiMH/alkaline ones.

Pack of 5 duracels non-rechargeable alkaline weigh 114g including packaging (home depot). Pack of 5 energizer non-rechargeable Li-Ion weigh 41g (amazon).

duracel alk AAA weight/cell = 18-21g (depending on packaging weight) energizer Li-Ion AAA weight = 5-8g (depends of packaging) rechargeable Lion weight = 9-12g (found on Amazon)

These don't state whether they are rechargeable or not but could be worth it if they don't drain too fast just for the light weight consideration (5-8g 1.5v):

Sunlabz Rechargeable (8-11.3g/cell, 1.2v) https://www.amazon.com/SunLabz-1000mAh-NiMH-Rechargeable-Batteries/dp/B00J18PFIO/ref=sr_1_3?ie=UTF8&qid=1478843835&sr=8-3&keywords=AAA%2Blithium%2Brechargeable&th=1

Seems to me the lower the capcity, the lighter it's going to be.

YOU'RE WELCOME!

The lightest one with the best battery life would be a A675 Hearing Aid button cell. Such a Buttoncell with 660mAh should last 110 hours on paper and a otherwise stock G305 weighs about 70g with this mod.

Soldering would be required though since you would have to replace the AA Batteryholder.

EDIT: No, using other batteries does not affect the performance of the G305 and it does not harm it. I'd recommend going for a Lithium AAA battery since it's the lightest AAA afaik.
