AA Battery leakage.

AA Battery leakage
Probably alkaline batteries.

Suggestions for neutralising/dealing with resulting white goo?

Body of torch is aluminium. It is a very useful 3watt Aldi LED torch that they have not had in for a while.

Vinegar to neutralise, wash well in water and detergent, rinse with water (preferably de-ionised), rinse with clear methylated spirit or IPA, dry, contact spray or Contralube770.

Its potassium hydroxide ( aka caustic potash) similar to caustic soda

Wash with water, neutralise with vinegar and rinse again. It may well have attacked the aluminium.

Keep a look out for the next time Aldi or Lidl have them or something similar again or buy a new one from somewhere else http://www.google.co.uk/#bav=on.2,or.r_qf.&fp=cd63140a0e8cac70&q=3watt+Cree+torch&tbm=shop

dont forget the 'marigolds'

Thanks for the info.

I have hopefully saved the torch. Aldi have not had them in for a year or two when I have been around.

I was surprised that it was Duracell batteries dated 2019 that had leaked.

I'm not surprised at all.
Google duracell battery leak
There are numerous threads on this subject, overpriced JUNK!!!

So what in the firmsare the better makes of alkaline batteries?

I do use GP batteries in equipment where the batteries are used hard for short periods and removed/replaced.

A few months ago extensive testing was done on AA alkalines
Duracell faired badly
Surprisingly, a lot of supermarket brand batteries were better value for money.

Duracell went down when Proctor and Gamble acquired them. They are marketing company, selling mediocre products for maximum profits

Maplin's own brand out-performed Duracell in a test I saw - at less than half the price.

I never leave any battries in anything these days, don't ask!

This was an on board torch in frequent use.

I certainly now take batteries out of all occasional use equipment such as my radio mics and test equipment.

Are Varta batteries any good?

"Which?" tested alkaline batteries quite recently, and Lidl Aerocell batteries (£1 for 4 AA/AAA, £1 for 2 C/D) performed so astonishingly similarly to standard Duracell that I suspect they are the same thing. I've been using them for ages without problems.

GP are the only alkaline batteries I have used that leaked.

I have gradually replaced all of my (many) AA batteries with eneloop rechargeable batteries. Unlike NiMH rechargeables, they don't self-discharge, but can be recharged, so useful for things like torches and remote controls.

Eneloop batteries are NiMH.

OK in remotes perhaps, but the low voltage of rechargeable batteries makes torches very dim.

I know the voltage is lower, but I hadn't noticed a problem with my torches.
