Interesting that people have found Varta OK. I bought some recently from my local B&Q, for my Bosch electric screwdriver which only gets occasional use. (4 AA)

After only 1 month and very little use, the screwdriver stopped running and I found the batteries were leaking heavily. Won't be buying them again. I normally use the cheapo ones from Lidl's and have never had any problems.

I rate Varta as good is this respect, but i have seen two of their AAA's leak. One was in a batch of many hundreds of 'in date' cells still in their wrapping, the other was in a remote control that demands a small quiescent current from it's cells. I find this low trickle to be a problem for some alkaline AAA's- they don't like it up 'em, for some reason.

I would check the electric screwdriver itself for issues (if it hasn't been killed)

Luckily I spotted it in plenty of time and it has been fine since.

I agree with others about very low current draw seeming to be an issue for alkalines, in remote controls etc. I still happily use Zinc batteries for this application. Never had a problem with them.

Coincidentally I have just had a blue Varta AA that was in a Maglite torch leak. Fortunately the leaky one was at the screwed end cap and corrosion wasn't bad enough to prevent removal. They were well within date and "Made in Germany".

About zinc-carbon batteries, I haven't seen any for sale in years here in Sweden. Even the cheapest odd brands are alkaline now.

I donít use zinc-carbon anymore, just Alkalines (with some Lithium AAís as backup to NiMH for a digital camera). I used to use Duracell for high drain applications, and cheaper brands for everything else, but then I saw the light.

Well, 2 lights really, one was that Duracellís seemed more likely to leak than other brands, the second was that the discount supermarket own brands (Aldi were best, Lidl not far behind) had very similar run times to the premium brands (according to a consumer magazine, and my own experience in some heavy use applications), but at 1/4 or 1/5 of the cost (25p/cell).

On leakage, I have been checking used cells for leakage for several years now, and found 17% of Duracellís had leaked (1 in 6) vs less than 2% for Lidl, Aldi, and Panasonic cells (less than 1 in 50). Iíve seen a few other brands, but not enough cells for a statistically significant conclusion (actually, none out of a small number of cells had leaked), but leaky Varta cells have been mentioned on here a couple of times - has anyone used enough Varta cells (a few dozen?) for comparison?

I brought some Agfa Photo branded zinc/carbon AA batteries from local Boyes which were terrible for leaking, especially towards the end of the battery's life. Although it wasn't a major lost, I made the mistake of leaving them in a cheapo battered transistor radio I had in my shed over winter. When the radio wouldn't work this Spring, checked the battery compartment and they leaked so badly you'd of thought the radio had be sitting at the bottom of a pond for years.

I'm trying some of the Poundland Kodak Xtralife Alkaline AAA's currently with my personal FM radio I have for when I'm on my walks. These ones have a 10 year guarantee which expires 08/2030(mfd 08/2020). Alright so far no leaks and lasting well, that is using the radio 4 to 5 times a week at an hour at a time for the past 2 weeks, still on the first of 2 AAA's.

I have always found the Poundland Kodak Alkalines to be excellent batteries.

I've always found over the years that Asda Alkaline do not seem to leak/ have a comparable £ for £ value with most of the best (considering they were used in test kit which could be left on), so I always bought two sets of each. Otherwise, for remotes in the house I buy pound land/Aldi rechargeable(NI MH of course as they are 1.5v)
