Do slim rechargeabble AA batteries exist?

N0bodyOfTheGoat

I've received a Crops NRX35 front light as part of a good bundle deal from Planet-X (2x Crops MX1 rear lights; Cateye LED hi-vis vest; Vapextech quicker charger with 4x 2700 mAh AA batteries... all for £60), but I have a slight problem...

The AA battery compartment has very tight clearance, preventing both my Vapex AA rechargeables and hybrids from being used, as they are ~14mm diameter (rather than the ~13mm diameter of non-rechargeables).

Does anyone have any ideas about brands that do slimeline AA rechargeables, ideally > 2500 mAh :?:

My uniross hybro seems to be 13mm.

Peel the plastic off the outside?

Aren't they called AAA batteries? /smartarse

AA batteries are either 13.5mm or 14.5mm wide.

Google didn't help, but I'm sure if you just go and buy a few different brands you'll find something. :?

ask in maplin, they'll probably know and may stock them

Is that a technical spec? It is a pain that all of the new Smart lights I've bought have thinner AA openings than in the past. None of my 2900mAh Vapextech fit But my old 2700 mAh Vapextech did, so I assume they are of the thinner variety.

It was this that made me surprised that the 2500mAh ones mentioned above were too fat, as I would have hoped that it was only the 2900s where they were trying to pack in more material.

@NO: If you do find some high capacity small diameter ones, please report back - I will want to order some soon as my 2700s are quite old.

@Biondino: :P

Just because they say they are 2900 mah doesn`t mean they are, what`s wrong with uniross?

True.

Why not Uniross? Well, Vapextech get reasonable reviews and the distributer lives about 400m from me, so it is more convenient

But don't worry, if Uniross fit and do a reasonable job, then I'll get them.

Annying isn't it. The girlfriend's cateye rear light won't take the new AAA batteries I bought, but some older maplin own brand AAAs do fit. How abou thaving a standard and sticking to it? :roll:

Yep. Funnily enough, I was in uni doing some CAD. I had just looked up the sizes of batteries two minutes before opening this thread. Even more ironic; I was making a light.

I just got some 7dayshop Hybrio-equivalents that seem to be marginally slimmer than the real Hybrios, so they may be worth a punt.

N0bodyOfTheGoat

It looks like there may be hope then!

White Line: Just unpacked the new Vapex 2700 mAh that came in the bundle, but sadly they are too wide also.

I had a quick look on the Uniross site over the weekend, but I did not see any 13mm AAs rated over 2000 mAh... Might have been blind, will double check.

Will google 7dayshop as well.

Cheers all!

I have uniross 2700`s and also have uniross hybrio 2100`s which hold their charge much better. I only measured the hybrios as the others are in the freezer.

Ah! :idea:

So that is why the rechargeables in my Cateye LD1100 are so "snug"!

Weird.
