First of all, it would probably help if you listed the Model Number.
I did a Google Search on "animas ping battery problems" and found several links to information.
It appears that with the RF feature turned on, on some models, the battery life is rather low.
Also, there is/was a recall on certain models as listed below:
Animas Corp. has issued a recall of battery caps used with its OneTouch Ping system and insulin pumps (models 2020, IR1200, and IR1250). The dysfunctional battery caps can cause a loss of power and a system reset. This could stop the flow of insulin, leading to dangerously high blood glucose levels. For more information, contact the company at 1-866-423-4087.
I hope that the information is helpful.
