Could this work - heated gloves off several AAA batteries?

[trevor saxe-coburg-gotha]

Would it be possible for, say, 4 AAA batteries to generate enough current i.e. warmth to heat gloves for use on a bike? If so, for how long? Perhaps a small 9v battery like those used in guitar effects pedals might work (or two of them). This wouldn't be too bulky or heavy - and would mean that if your bike didn't have a battery (like my old CRM), you could still have warm hands.

I haven't googled this - they may already exist. I'm thinking such small batteries couldn't really generate enough useful warmth for a sufficiently long enough time (e.g. two hours or more).

I'm no expert but, to generate heat uses a relatively decent amount of power. It would probably work but I would have thought you'd run out of juice quite quickly.

Four AAA batteries would appear to give an output of 5000mAh, if buying top brands. I would suggest something like this would be better, as it's rechargeable.

For a heat source, you can get heat mats for snake tanks with an output as low as 10W. Wouldn't take much work to fit inside a glove or mitten and the insulation should retain the heat quite well.

Should be pretty simply electrically too, bonus points if throw in a thermal cutout to avoid cooking your hands.

They do work, to a point. The idea is they heat your hands up, and you turn them off, letting the insulation do it's job. Designed for walking about in snow, not griping bars at 60 in the winter.

I can remember my das instructor had a set, had a pair of heated socks too. The other instructors took the mick out of him for it.

Sportsbikeshop.co.uk do both the socks and gloves.

We've had this discussion before on BCF.

IIRC Maplins used to sell a pair. They were not for constant heating though. You were to turn them on for a minute let them heat up and take the edge off the cold.

They were OK for walkers. There is a ethanol fuel version you see in military surplus stores too.

The problem is they're deemed not very useful for bikers primarily because while you're being heated you're also being cooled by the wind and even if you seal it up the stored heat won't last long against the wind cooling so you'd need it on constantly which the batteries can't take.

The heat jacket type brands make a battery pack for remote power.
I would look at that.
The AA home improvement would only last as long as the battery. Which would possibly be half an hour.

You could use solar.

Slightly OT, but I bought a battery powered heated vest in Maplins (in a spring sale), and wired it into the mains my bike, via a 10V converter screwed onto a heat sink. 3 x 1.5V AAAs per side = 9V total, drawing 10V it runs warm without too much nipple scorching.

You could likely ghetto up something similar with battery powered gloves.

I diy'd a set of liner gloves from a pair of Aldi windproof running gloves in the sale bin and some beadalon stainless wire. Connectors at the cuffs, and a wire that runs up each arm and down to the waist. Cable runs on to a din connector.

It is bit of extra faff, but toasty warm hands (especially inside muffs) and cost me less than £15, some time and a bit of internet research. Been in use for three years.

Maplins were selling AA battery powered heated gloves a couple of years ago. (Snowie tried a pair on & got an electric shock off'em )

Why try making something that already exists, you can buy off the shelf?

Bound to be some on e-bay, some-where!

Eh? Now I am even more confused.
Not trying to piss you off, trying to understand what you are about!
On the topic of 'current' affairs, my top ponder of the day is why my range-rover appears to go from 0-140mph, when I turn the ignition on, and then slows to 90 when I close the driver's door....all without budging an inch on the drive I 'think' the answer is something to do with it being built in Birmingham..... but beyond that, it's got me mowing the bald-spot.
So, Yes, AAA's could power a pair of heated gloves; Maplin used to sell'em... why do you wonder? Seems to be more behind the question than in it.

I find it amusing that we're sitting above a hot block of metal with wheels attached yet have to meddle with heated gloves and the like to deal with an old problem.
