Recent battery pricing update has me checking sales pricing.
When did the Silver battery, such as 78PS, become Gold. The 78PS has a 30 month replacement warranty. By definition 30 month warranty is a Gold battery. The battery part number and label suggest Silver but a Silver battery only has a 18 month warranty.
The National Retail Program lists Gold 42 and Gold 30, along with Silver 18 month warranties.
What did I miss and when was it released.
