Recheck old school Power Supply

Re-Checking my old school power supply HTC-5 from Elcom Research.

last weekend I changedbattery of my car. Old battery don't fail stored energy.I get come to my home and I have idea to make backup the power of my station.

The power supply is good condition to supply 12V (on check 11.98V)
