What is the Amperage Draw of the Bulldog 4000 Pound Powered-Drive Jack

Question:

What is the required amperage of the Bulldog power jack 4000? I have one. I have it connected to a electric brake battery 12v 5/a H. The jack works fine for when using it to put on the truck, but it acts like it has a lack of power while lifting. I am not sure if the battery is adequate and if it needs charging or should I use a different battery with a charging kit? Thanks!

The Bulldog Powered-Drive Jack is designed to run off the vehicle electrical system that has quite a bit more power. It has a 35 amp breaker inside so it probably draws around 30 amps depending on how much weight it is lifting. I would hook it up to the power circuit on the 7-Way connector so it has more power.
