said by February26 : Agreed. I read this as if a customer wants a "backup battery" to the main battery, the main battery being included in the current equipment rental fee...but I have not seen the "confidential" documentation.
You do realize this "article" is complete rubbish. There's no charge for the battery and the battery health has been monitored for years. When someone calls in I can see the battery status in GrandSlam and if it's depleted I get them to the Battery Replacement Group who sends them a new one free of charge.
