Review on πŸ”‹ Durable Duracell D389/390PK09 Silver Oxide Electronic Watch Battery, 389/390 Size, 1.55V, 70 mAh Capacity (Pack of 6) – Long-lasting Power Solution for Electronic Watches by Eric Graves

Revainrating 5 out of 5

Four of these batteries replace a 6V PetStop UltraElite "3011 " battery for 1/4 the price.

My PetStop friend wanted $50 for a new battery. Four of these stacked batteries have the same specs and cost $12. Don't be fooled by the many inexpensive lithium or alkaline options. Silver Oxide is the longest lasting battery available in this form factor. I folded four of them and wrapped them in a layer of tape. Fits perfectly.

Pros
  • 1.2V Endpoint Voltage
Cons
  • Damaged
