Review of Century Battery Charger

I've had this battery charger for about 10 years. I don't know if it's still in production.
It's a dual range charger that charges in 6v at 12 amps, 12v at 2 and 12 amps and a quick start feature 12v at 70 amps. It also has auto shut off and manual charging.
It has a charge complete indicator and a reverse connection warning light but no "bad battery" indicator.
The ammeter indicates the amperage that the battery is drawing from the charger. The meter will read the max output rating of the charge setting only if the battery being charges is fully discharged.
