Review: 312 Rayovac Extra - The hearing aid batteries are great but I don't like the child protection package they come in. They are very hard for seniors to open. If children were to come they are always put away in a drawer. I believe I ordered the regular package but came as child protected. Review: Bad packaging - The batteries are extremely hard to remove from the packaging. Basically you have to destroy the package to get the batteries out. Then you have 6 loose batteries. The batteries seem not to be long lasting either. I'll try to find 312's with better packaging. desertcart used to sell 312'2 in a very easy pakage. They seem to have dicontinued them. ## Features - Battery Type: Zinc-Air - Voltage: 1.45V - Capacity: Typically 310 mAh - Color Code: Orange - Dimensions: 7.9mm diameter x 5.4mm height - Weight: ~0.86g per cell - Operating Temp: -10°C to +50°C - Mercury Content: 0% Mercury (Mercury-Free) - Standard Designations: IEC: PR48; ANSI: 7000ZD ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D6BTF781 | | Antenna Location | Hearing Aid | | Battery Capacity | 185 Milliamp Hours | | Battery Cell Composition | Other Than Listed | | Battery Cell Type | Other Than Listed | | Best Sellers Rank | #44,635 in Health & Household ( See Top 100 in Health & Household ) #30 in Hearing Aid Batteries & Chargers | | Brand | Rayovac | | Customer Reviews | 3.6 out of 5 stars 930 Reviews | | Global Trade Identification Number | 10012800539670 | | Item Weight | 0.09 Kilograms | | Manufacturer | Energizer Trading Limited | | Number of Batteries | 60 Nonstandard Battery batteries required.

They are very hard for seniors to open. If children were to come they are always put away in a drawer.

Basically you have to destroy the package to get the batteries out. Then you have 6 loose batteries. The batteries seem not to be long lasting either. I'll try to find 312's with better packaging.

I enjoy the fact that they will last for one whole week. Each 6 pack wheel, will last me 3 weeks. I insert my aids in usually early, around 7-7:30 am, and put them away in the late evening. ## Frequently Bought Together - Rayovac Extra hearing aid batteries size 312.
