I have a Shumacher SE-60 that is 25+ years old and can boost to 50 amps. It has an analog Voltage scale. I wish it had an amps gauge and have thought about adding an amps gauge for about $30 but tell myself “you can always just clip your Hall Effect AC/DC Fluke onto a wire. Lately I have been plugging the AC cord from the charger into a $22 Kill-A-Watt power meter and watching how the watts decline as full charge is approached.

I also have a Pulsetech Xtreme 4 amp desulphating charger. I really think it helps extend battery life. I like how it is waterproof. I also use the Kill-A-Watt power meter with it. The Xtreme has LEDs for 25%. 50%. 75% and 100% charge. It needs an additional LED for 90% charge IMHO.
