Harder to open than a jar of pickles!!

I can’t believe the package is this hard to open even with scissors. Total fail! This product is used mostly by seniors and you make it practically impossible to open. I had to get out my wire cutters to open the darn thing and then had to make three cuts to get out one battery. Maybe put some directions on the package.
No, I would not recommend this to a friend.

Thank you for submitting your review. Many thanks for you feedback on the new child-resistant packaging. We have changed the packaging format to be in compliance with Reese’s Law, which states that all button, coin and hearing aid batteries – and devices powered by those batteries – must be contained in child-resistant packaging that features specific warning copy.
The products have been subject to rigorous independent tests, confirming that the new packaging is 100% child resistant*, and zero batteries were accessed by children during CRP testing.* The new plastic dial includes additional staking points for extra security. By that nature it does mean that there will be a difference for users in how to access batteries in the pack, compared to previous packaging. The independent testing also showed that 99% of seniors were able to open the pack for the first time in under one minute*. On the second attempt, this time halved* so we found that consumers become faster with more familiarity and with instruction. We want to support everyone through the transition to child-resistant packaging and have prepared the following video that shows you how to open the pack.

The batteries are great, last longer than other batteries I've tried. But the child-proof packaging is terrible. I'm a senior and have trouble opening the package. You need a lot of muscle in your hands to cut it open, and I don't want to carry scissors with me if I need to open the package away from home. Try again with a better package.
I would recommend this to a friend!

Sadistic Packaging
on December 28, 2024

Gender:Male
I had a new box of 312 10 packs. My father in law was visiting and needed some batteries. I handed him one of these new packs and he was totally unable to get it open, Now it was my turn to try. It was awful. I have good use of both hands and was using kitchen shears. I had not imagined something so poorly designed.
What if I had arthritis and poor vision? All I have to say here is that the product development people and admistrators who supervised this unholy packaging have totally failed their customer base. I for one will not purchase any more of their products.

Rayovac 312 Extra Advanced Hearing aid Batteries
on July 28, 2016
Posted by: Chas Ellis
from Auck New Zealand
Gender:Male
I bought these 28. 7. 2016 and found that they each measured 1.176 Volts.
Since my hearing aids shut off when the battery power reaches 1 Volt I can now understand why I get so little use out of Batteries manufactured by Rayovac
Would you care to comment???

TOTAL WASTE OF MONEY!!!
on August 3, 2016
Posted by: M Joan
from Buckingham, PA, United States
I bought the double pack of batteries and 3 out of the 2 packages worked in the
usual length of time. All the rest: The battery didn't NOT WORK AT ALL or it
would work for 1 DAY and it was finished. I had to throw out the entire packages of
batteries. Being a hearing aid wearer and keeping spare batteries in my bag for use I was TOTALLY FRUSTRATED AND ANGRY when attempting to put in a new battery when I was out for the day - to find I could NOT rely on these batteries and I
cannot hear without the hearing aids. Ray Vac batteries (and not the 1st time this
has happened to me w/ Ray Vac's batteries are just the WORSE!!!!!!

STUPID!!!
on September 13, 2024
Posted by: JenniferIS MAD
from Texas
Gender:Female
ineffective as I don't carry scissors in my purse. So guess what I did. I opened EVERY ONE and just had the loose batteries in a baggie. They ended up in a pocket and I washed them! SOOOOOOO Batteries are ALL OVER my house....loose in my purse even because the baggie broke at one time. It is absolutely the STUPIDEST design imaginable! WHO was the IDIOT that though this would be safer??? I would bet my salary that that 99% claim is a BALDFACE LIE!

child resistant package

This new child resistant package not only keeps children from opening pack, but also seniors. This packaging is horrible, takes an hour to open it. Give us an option of either child resistant, or old dial open one.
No, I would not recommend this to a friend.

CHILD PROOF PACKAGING IS TERRIBLE
on November 14, 2024
Posted by: OLD MAN RULES
Gender:Male
I UNDERSTAND THE NEED FOR CHILD PROOF BUT THE FACT THAT YOU NEED TO CARRY SCISSORS OR SOME SHARP DEVICE TO ACCESS A FRESH BATTERY IS COUNTERINTUITIVE. YOU CAN'T ALWAYS HAVE ACCESS TO A SHARP DEVICE WHEN NEEDED BECAUSE OF A DEAD BATTERY. I WON'T BUY THEM ANYMORE UNTIL YOU REDESIGN THE PACKAGING.
No, I would not recommend this to a friend.
