I sent an email to batteries.com to complain about their service and here’s a portion of the response I received from Chris McKenna, Product/Warehouse Manager, Batteries.com.
I apologize for the experience you just encountered. We’ve been experiencing some technical difficulties with the live chat software. It randomly kicks our reps out of the program, ends chats automatically, etc. The IT department is working to fix the bugs. I certainly appreciate the feedback.
In response to your inquiries, no, there is not a longer lasting rechargeable AA than the Energizer 2500mAh version. This is the highest mAh rating for consumer rechargeable AA in the market. The 2700mAh is soon to come. However, if you were not satisfied with the predecessor, this will probably not alter your opinion. There are a few steps you can take to ensure you get the most runtime out of your batteries.
Again, if you are having tech difficulties with Live Chat, you’re better off disabling it until the issues can be resolved.
Update: I also received a phone call from Dale Petruzzi, President of Batteries.com telling me that they are having problems with Chat and that they are actively working on the issue. Dale seems to have been around the Ecommerce block and had great insights into their strategies for search and blogging. In the end, I was satisfied with the call and their service.
