they're good? do they spill acid or liquid over time that damages controls or electrical appliances?

I'VE USED THIS BRAND VONIKO FOR A WHILE NOW. LONGER THAN A YEAR... MAYBE TWO... THEY HOLD A CHARGE FOR A GOOD WHILE JUST SITTING IN MY BATTERY BOX.. LIKE, I STILL HAVE SOME YEAR OLD 9V'S AND SOME AA'S... AND THEY'RE STILL GOOD.. MY ONLY COMPLAINT IS WHEN I USE THEM IN HIGH DRAIN DEVICES, I.E. FLASHLIGHTS.. THE ONES IN MY TV REMOTE HAVE BEEN THERE FOR AS LONG AS I CAN REMEMBER... BUT THE ONES IN MY FLASHLIGHTS... NOT SO MUCH! THEY GIVE UP THE JUICE TOO QUICKLY IN THAT KIND OF APPLICATION.. I'VE ALSO TRIED THE ALL MAX( OK )_, SUNBEAMS ( SUCK )_, AC DELCO'S ( BEST VALUE: A+ ), RAYOVAC ULTRA PRO ( GOOD )_ & I'VE USED ALL OF THESE IN AA, AAA, C, 9V AND D SIZES... AND DURACELL IN D AND ENERGIZER IN AA, 9V AND D SIZES.... OUT OF THE CHEAP ONES, THE AC DELCO'S HELD UP THE LONGEST IN HIGH DRAIN FLASHLIGHTS... AND THE OVERALL BADASS IS OBVIOUSLY ENERGIZER LITHIUMS... EXCEPT FOR THEIR ALKALINE 9V... THE VONIKO 9V WAS ON PAR WITH THE ENERGIZER,...NOW, PLZ DON'T GET ME WRONG, VONIKO IS A GOOD BATTERY, IT'S JUST DEPENDS ON THE APPLICATION, TRUTHFULLY... FOR HIGH DRAIN DEVICES, I SHOULD BE USING LITHIUM AA & AAA BUT I DIGRESS... IM CHEAP CHEAP AND RATHER GET 100 VONIKO AA'S FOR $22 BECAUSE I KNOW MY KIDS ARE GONNA BURN UP 1/2 OF THEM EASY, WHILE I'LL DEVOUR THE OTHER HALF IN COMPANY USAGE.. GOOD LUCK!

Good cheap alkaline batteries

Seems to be a decent battery brand. I put a a AAs in a roku remote which gets heavy use and now over a week later it still shows 100%. When I test the battery with a cheap little battery tester it usually shows above 1.6 volts. They also look nice and it's easy to tell which way is positive and negative due to the blue and white coloring. And of course, the price is right.

Seriously Impressed – These Batteries Go the Distance!

I don’t usually get excited about batteries, but Voniko has completely changed the game for me. I bought the 24-pack of their Premium Grade AAA batteries a few months ago, and I’ve been blown away by how reliable and long-lasting they are.I’ve used them in everything from TV remotes and LED string lights to kids’ toys and wireless devices, and they’re still going strong. What really sold me is that they’re completely leakproof—I had a bad experience in the past with another brand ruining a remote, but these give me total peace of mind.The packaging is also super convenient, and the 10-year shelf life means I can stock up without worrying about waste. You can tell the quality is premium just by the feel of them. No issues with dead-on-arrival batteries either—every single one has worked perfectly right out of the box.Bottom line: if you’re tired of replacing batteries constantly or dealing with messy leaks, Voniko is 100% worth the switch. I’ll definitely be buying again if I ever run out of them that is…😉

Long-Lasting, Leakproof, and Eco-Friendly

These Voniko Premium Grade AAA batteries deliver impressive performance. They last longer than standard brands and are 100% leakproof. The 10-year shelf life is a bonus, and they're mercury and cadmium-free, making them a safer choice for home use. Great value for a 24-pack.

Good batteries.

I haven't done any electronic testing. But it seems like these batteries last longer that the batteries that I get at the big-box stores.
