"SMART" portable battery chargers are just about useless. Save up a bit more then something that works -- a 400 watt Megawatt connected to a 4 hour wind-up timer like an INTERMATIC.
Possibility of a SMART charger ruining your battery = 100%
Possibility of a Megawatt ruining your battery = only if you are unbelievably careless (takes a lot of effort and stubbornness even at that)
The timer saves the day. The INTERMATIC timer does not have a continuous on setting -- 4 hours is it. If you keep the generator running for a month or so and rewind the timer 400 times you probably will damage the battery. This is NOT an old-fashioned uncontrolled garage charger. It has a finite voltage limit where you fix it -- recommended 14.7 volts for wet cell batteries and 14.4 volts for AGM.
