Fuji Enviromax AA battery, extra heavy duty, manufactured to be eco-friendly and powerful, LR6 Carbon Zinc - (48 pack)

good value for money

Claimed to be better constructed and more environmentally-friendly than their equivalents of years ago. Personally, alkaline batteries have been the personal default for decades originally for photographic equipment but latterly for remote controls, audio equipment and much else, several portable alarm clocks included. Superficially, their construction appears very similar in execution and standard of finish to the more expensive alkaline alternatives.Several repeated incidents with two battery-powered alarm clocks were batteries were replaced almost at the same time and with similar battery types has proven that the 'wisdom' of using alkaline for everything may not be advisable. An article found claiming that many clock movements can be 'over-driven' to the point of total failure by some high power batteries was noted and specifically the failure by their manufacturers to recommend them for use in clocks; zinc carbon batteries are said to be far safer to use although less readily available than they were.The manufacturers claim that "Fuji Enviromax, Eco Friendly Carbon Zinc Heavy Duty Industrial Batteries, AA, Pack of 12" are especially well-suited for use in clocks and other equipment where the potential for leakage and consequent internal corrosion would have once resulted in a recommendation to use alkaline only. Fuji think differently about these.It may be worth accepting the recommendation especially as these are substantially less expensive than alkaline batteries size-for-size and often a direct alternative.

If you as me to much toys this item is compulsory in your home.

All ok

Bought for our smoke alarms. Only complaint is they came in a multipack, but not with a great best before date (we only have 2 alarms and they're the only thing we own that requires a 9v). We gave some to family and friends, so even better value really if you wanted to split the pack with some people!

I'm using three of these at a time, to power a medium length string of low powered, outside, Christmas lights. I could have used re-chargeable batteries, but they don't always work well with some products. And, as I had some of these Fujji batteries from a packet I had got from Amazon for a clock that needs low power batteries, I have tried them in my outside Christmas lights. Three have so far lasted five night, powering my modest length string of outside lights. For a minimum of four hours a night; sometimes for six hours. I have turned the lights' brightness down to about two thirds full strength, but they still look good. PS. These lasted circa 7 nights, so a bit more than 30 hours. Considering the low price I felt that was ok.

I bought a new clock and was advised to use this particular type of battery. Having bought them the clock did not work anyway so do not know how long they would last in use. The number you get though is, on the face of it, good value for money. Service was good and would recommend the seller.
