A. What are silver oxide batteries used for?
Potassium hydroxide batteries are used primarily in LCD watches with backlights, and sodium hydroxide batteries are used primarily in digital watches. Using potassium hydroxide as the electrolyte allows silver oxide batteries to operate even under heavy draining conditions and also at lower temperatures.
B. What is the shelf-life of silver oxide batteries?
Silver oxide batteries become hazardous on the onset of leakage; this generally takes 5 years from the time they are put into use (which coincides with their normalshelf life). Until recently, all silver oxide batteries contained up to 0.2% mercury.
C. Do silver oxide batteries expire?
The Expiry date (ED) is printed on the packaging of Silver Oxide Battery. The Expiry Date on Silver Oxide Battery means the expiration of the recommended use period. The Expiry Date is determined after three (3) years from the manufactured year and month.
D. Do batteries go bad if not used?
Since primary batteries can't be recharged, any self-discharge is permanent. Most disposable batteries have an expiration date printed on the packaging. But if the unused battery is not connected to anything, it will probably be fine after four years but can't be guaranteed
E. What is a low-drain battery?
Good only for low-drain devices like clocks and remote controls. Use is for digital camera or other high-drain device. (These 2 are okay, but since cameras go through batteries fast, you're better off with a rechargeable battery that you can reuse.)
