No, we do recommend a 6 v 5 ah spring top high quality brand battery.
If your feeder kit is compatible with it there will be wiring on the back, and the side that the wires on the varmint buster will connect to.
You slide the battery in the side spring side first, and lock it in with the metal retaining bracket.
We recommend that the first time you charge the battery for 8-12 hours and disregard any lights on the charger. After the initial charge, you will want to charge the battery when it gets low and never charge the battery for longer than 24 hours.
The unit does not come with hardware for the legs. The legs actually slide in together and will stay, bolts or bailing wire can be used if desired.
Check and make sure you have a good AA battery inserted fully in the battery compartment in the back.
