The juice lasts about 10x longer than the batteries, so they'd have to either make them use much less juice, or use larger batteries.
Consumers are paying upwards of $20 for vapes that last less than a week with heavy use, or about 2 weeks with low/average use, so I don't think a dollar saved on batteries is really as much of a concern as "why should I buy your vape vs one of the 5 dozen competitors'"?
