Anne,
You are welcome to WizIQ but I would ask you to evaluate your purpose in blogging here. This is a community of teachers and learners. Not an advertising forum for any product one would try to sell.
Please consider giving classes about batteries. This would still give you exposure to potential clients and it would offer knowledge which is our purpose for being.
I bet there is a lot of great information you could share about batteries in classes here at WizIQ.
