It's a battery maintainer not a charger. It replaces the power lost by just sitting. I have one of those I put on my lawn tractor when I don't use it for a while. I think it helps?
i understand fully what it is, but would it help the longevity of a battery using EOC? even when i end a trip w/ engine off, for example, if i try to restart w/in several minutes, it is a little slow to turn over.
i could try it w/out wasting too much $$$. we have a car that sits for long periods of time anyway. getting out the charger every time bites.
For EOC, I don't see that item making much difference, especially if you have a new battery. I doubt that it would take more than a few seconds to return the same amount of power to the battery that a 1.8 watt solar charger would put in in an hour. For maintaining the battery on a car that sits for a long time between uses, however, it sounds like a great idea.

I see motorhomes and power boats with bad batteries all the time. The lead acid batteries are all bowed on the sides which is a sign of constant charging.
That being said, a battery maintainer should keep the voltage from going above a certain value. If this product does that and you keep the solar charger connected 24/7, then yes this is a worthwhile investment.
