Fyi, it is a charger, not a maintainer like the Ctek. I used it to return some less than OK batteries back to a useful condition.
Obviously you didn't read the reviews.

I use these on my generator, ATV, etc.:

Cheap enough to have several and not have to alternate. It is a true maintainer with a microprocessor, not just trickle charger. I also have a good maintainer for the "good" cars but wouldn't be concerned about the chap ones in a pinch.

I read the one star reviews to see if there was anything consistently poor. I have brought back batteries from the grave with my Optimate 6 by Tecmate, it's not some cheap POS either.

The Charger I just purchased (In Post #56) has exceeded my expectations. 
I'm impressed (You know that is hard to do - LOL). For a $27 Charger that functions excellent with a complete digital display that shows you everything as it is going on - AMAZING!
- You select between Auto, AGM, Motorcycle, and Repair Programs. Nothing else is needed by the user.
- The only difference between Auto and Motorcycle is 8 vs 1.5 amp max charge rates possible.
- AGM program uses a ramp up in voltage then down, then off (no charging) for a few seconds, then back on again. This is to prevent "boiling" the water out.
- The repair cycle Ramps voltage up and then back down (pulse charging) vs keeping a sustained high voltage. If the battery checks out OK, repair will turn off within a few seconds!
