I have a similar one connected for months at a time. I added a fuse to the positive lead coming off the battery in case of a short circuit. The car is in our garage so I put a cardboard box on the car hood to remind us the battery maintainer is plugged in- so we don't drive off with it still connected.

Mine is usually parked in the garage also, I usually just leave the hood up.

0.8A is pretty low ... may work as a maintainer if your battery is in good health but for that kinda $$ I'd rather get a more powerful battery maintainer from Amazon.

Something like the Gooloo 6V/12V 6A battery charger + Maintainer from Amazon, it's ~ $35.

If you are going to connect something like this for weeks at a time over Winter, may I suggest pairing this with an appliance time set to turn on for a few hours a week? There have been reports of similar devices when connected to the battery fail in the sense that they fail to detect that the battery is full and end up overcharging the battery. By placing a weekly appliance/light timer on it, the charger is off most of the time limiting the possibility of overcharging.

I wouldn't trust that at all to be left charging by itself for weeks as a maintainer supposed to do. 0.8A is fine. Another RFD'er got the Battery Tender Jr which is 0.75A and was able to fully charge their battery over a period of a few days which is exactly what a maintainer is supposed to do.

I am doing this with a Kasa smart plug.

I think there are a couple things you can do. Some ppl put a timer to it, so that it only turns on for say, 3 hours in a week, that makes sure you won't overcharge your battery (or worse, cause fire hazard or what not)

But the other thing is, these battery maintainer are all 'smart' chargers that are designed to be left hooked up to a battery all winter, and not only it shouldn't overcharge your battery but moreover, it is supposed to go through different stages of charging cycle to keep your battery healthy. Whether you trust these smart chargers to do that is another thing, but at least reviews seem to indicate ppl have left it hooked up throughout Canadian winters without any problem.

I have a Battery Tender Jr plugged into my 1972 Buick's battery all the time (no timer), and it keeps it topped up without an issue. less than an Amp is not going to damage batteries that are typically 25Ah+ (and those are on the small side).

I used to use my CTEK 4.3 for float charge, but when I inherited the Battery Tender Jr, I use that for top up, and keep my CTEK free for more top-up/charging duties.

I'm actually the guy that is telling everyone to do just that for months.

It's not a question of 'smart' chargers or not in this case but rather if GOOLOO is actually a brand that isn't basically crap. I consider brands like GOOLOO crap brands. If you are going to depend on a smart charger being smart, then get a better brand that can be depended on.
