Query: Love it, but it eats batteries

We purchased the Rok lift for our "almost" 5 year old son. He has been very enthusiatic about it from the moment we took it out of the box except for the fact that it "eats" batteries. We have to replace the batteries with alarming frequency, and it will often stop on ascension and have to be restarted when batteries are not brand new. The rechargeable batteries we have are not powerful enough to use. It also, sometimes, does not trip the switch to begin when pushed and must be manually started. We have not had any problems with noise and it works well when it has fresh power.
