I don't have this charger, so I can't make a fair statement on whether it is worth $100 for what it can do, but it is completely unnecessary to spend that kind of money just to keep your battery topped off, no matter how long. Anything decent quality that limits maintenance charge current to 100mA (or ideally closer to 75mA) should do fine for an otherwise healthy battery and vehicle electrical system.
You can build that out of $5 worth of spare parts. Consult battery manufacturer datasheets to see if they require marketing buzzword features to keep their battery topped off.
waiting for that DIY?
