Featured Not resolved

I have just opened my expensive LED LENSER flashlight to change the batteries (the Duracells it was supplied with). The light was still working, the beam just did not seem as bright despite not being used very much. The flashlight is less than 1 year old and the batteries have leaked inside. The expiry date on the batteries is March 2018

I have recently had to replace a Coleman lamp which was destroyed by leaking Duracell batteries.

Why waste money on so-called "top of the range" if they are no better than cheap no-name brand products?

I will never buy Duracell batteries again

Monetary Loss: $150.

Had an Experience with Duracell?

Perhaps it's a bit late but Duracell has a guaranteeprogram: http://www.duracell.com/en-us/battery-care-and-disposal/duracell-battery-guarantee

(found on http://www.flashlightuniversity.com/cleaning-a-corroded-flashlight/).

I have had a similar problem but trew the batteries away already.


Batteries which are drained of their energy will start to leak.Dropping electronics, moisture, a lot of other things can make a battery leak.

This happens to cheaper brands too, hits all of them. €150 in loss, have a great tip: contact cleaner. Buy a can, clean your electronics of the corrosion/ corrosive fluid. As Flashlights are simple electronics, the only "damage" is a corroded battery lip/ contact surface- which can disrupt the electric contact.

Clean it, instead of throwing away your flashlight.

Buy the cheaper brands, since they can be top notch, you just have to try some brands for good results.Think, research, and spend less time pissed off about a tiny first world problem.

Are you kidding?I've been an electronics tech for 35 years.

More often than not, the corrosion is so thorough, that it strips all the plating off the battery terminals. I have seen the corrosive leakage damage the traces on circuit boards and affect membrane switches. Sometimes the batteries short out, and swell so much that you can't get them out.

Duracell and other brands of alkaline batteries have been leaking during normal use for years now.

It is NOT just when they are drained. When I was a kid, batteries leaked all the time, and battery manufacturers replaced the damaged equipment. Then in the 70's, 80's and 90's they appeared to have the problem licked. Now however the problem has returned with a vengance.

And the companies don't care.
