Review on 🔋 Durable and Dependable: Duracell 6 (3x2) Duralock MN21B2PK Watch/Electronic/Keyless Entry Batteries, 12V Alkaline by Steven Ripley

I bought three of these packs to replace the regular batteries I had. I thought Duracell was better than generic and lasted longer. The first two batteries each lasted several days, in contrast to the conventional ones, which each lasted several months. I then opened up the rest and tested them with my battery tester and found that each battery was dying on testing. Some of them were dead before I even used them. The expiration date is listed as 2019, so there shouldn't have been any reason for these batteries to leak. All I can think of is that they may have been exposed to the cold for a while. However, my generic drugs are well past their expiration date. Basically, the batteries of these famous brands were mostly DOA. Very dissatisfied with this purchase. Let's go back to the old generics that were more reliable. I bought them in May but thought I'd leave this review in case anyone else has the same experience.
