Pros & Cons

Update Pros and Cons

The AI used to provide these results are constantly improving. These results might change.

Pros

The rayovac batteries last the longest (up to 7 days), and are the only batteries that i use in my hearing aids that perform consistently. They are consistently dependable. Expiration date 4 years out. Great battery life.

Cons

Worst batteries ever. Average lifespan is 3 to 4 days. Plastic waste alone offsets any possible improvements in longevity. My hunch is that they 'leak' power when un-yet-used in the drawer.

Highlights

Quality

The product works well but wish it would last longer then three days for each battery

Delivery took longer than expected but the product arrived in good condition.

Not only was the description incorrect, but they were shipped with the lithium battery label and restrictions.

His set cover the hole with the contact which probably isn't the best design, since these batteries require oxygen to operate.

Packaging/appearance

They are long lasting and i like the packaging because it is durable when i carry the batteries in my purse.

My biggest gripe with these is the packaging.

Competitiveness

It may be just me but after several years of wearing hearing aids i believe the rayovac last longer than the competitors.
