The problem with that 19 minute job is;
A. It has to go smoothly....no worn bolts, nuts, clsmps etc.
B. You need to add the time for you to find the LAME, discuss the problem, he clears the space, tows the plane, sources the battery, raises the paperwork, goods receipts it, does the change over, disposes of the packaging, takes the battery to the recycle place(done at a later date), clean up put tools away, push plane out and chin wag with you while you tell warries about the last battery.
C. Fills in the MR and raises your invoice.
D. Pays the credit card fees....or chases you for payment
Yep.....19 minute job.
