some batteries have good voltage but wont pass enough current. have any of the battery monitors tripped? how old are the batteries? word of advice dont let the boss buy you anything less than all 16 batteries. buy good interstate batteries they last 3-5 yrs or for 2x the cost you can get gel cells that last more than 10 years. i have a MRVF job running on 13 yr old batteries that is a testament to gel cell technology.
