Battery Charger Meter Adventure

I planned on putting in a digital volt/amp meter in this charger with a bad meter. Things didn’t go as planned. There was some smoke so no digital meter. Watch how to not to replace a meter. It’s all fun even when it fails.

New battery charger can it bring an old Gel cell back to life?

We will see. I think this old Gel cell is toast. But I wanted a charger for AGM (absorbed glass mat) so I got this one. You can check it out on amazon at the link below.
It is a Schumacher SSC-1500A-CA Ship ‘N’ Shore 15 Amp SpeedCharge Charger with Battery Clamps.


Installing 12v Quick Charge QC3.0 USB Charger & Volt Meter Combined Unit

This short video shows how I install a Quick Charge QC3.0 USB & volt meter all in one unit in a Daihatsu Hijet I am converting in to a micro campervan (See link below). The Quick Charge 3.0 USB Volt Meter is a neat little unit which provides 2x USB charging points which can charge at up to 3 amp, providing quick charging times for devices that accept higher charging. The unit is also backwards compatible for standard USB charging so it is a very hand unit. Along with the USB chargers, this unit has a built in batter volt meter, meaning separate meters are no longer required saving space and install time. I think it’s a very neat tidy little unit that would be suitable to be installed in any camper, motorhome, car, boat etc.

Schumacher Ship ‘N Shore Battery Charger SS-51A-PE Meter not working, solution and Schematic

Charging meter on Schumacher Ship ‘N Shore SS-51A-PE automatic battery charger appears to not be working at all so there is no indication of whether the battery is charging or not. This video shows the cause and solution to that problem in that the battery leads were defective and open circuit and therefore the charger was unable to deliver voltage and current to charge the battery. This video also includes a reverse engineered schematic initially created by someone else but edited by me to include some part numbers and descriptors. WARNING: I have seen different schematics for this charger model with substantially different component values and components (different SCR brands, different transistors, different resistance values) but essentially the same basic circuit. A really smart engineer has posted a very good article about this charger circuitry and design enhancements he would have favored. You can also see the schematic here:
