Will it keep car battery full in very cold temps 15 in winter ?
In NJ its winter, night temp currently dipping down to low 20 to t33ns, I dont go out for 3 to 4 days disabled. Battery runs minor things even when car off, plus low temps drain battery. so thinging a trickle charger or low amp charger will do the job hook it up when not going to use V 8 4.1 litter engine car fore 3 to 4 dAYs in this cold weather. So need somelow amp low profile small unit size like this to keep battery fully charged. Also tto not over chagre battery, Does this unit have float charge and over charge protection?

This should work well for you. It does not over charge and will maintain a fully charged battery. It cannot be used outside where it is exposed to snow and rain.
The manual states that it does have the "float" option, but it also states that on a car battery it can take 24-36 hours depending on how low the charge is. Also, by reading the reviews, the ones that were negative did say that on larger batteries, it tended to over charge. I am disabled as well, so I understand the need. I would just put it on when the weather drops really low and keep an eye out for the green light. I wouldn't trust the float option on a large battery. If it doesn't work, Walmart has a great return policy (just make sure to take it off at full charge so it doesn't damage your battery). Best of luck Rocket11213.
In manual say it does have overcharge protection but it not recommended you leave charger on full time.
This product would work well for you. It is logic controlled and switches to maintenance mode once it has brought the battery to peak charge. No need to worry about overcharging. Remember this charger supplies only 1.5 amps, so whatever the drain is in your vehicle, it must not exceed this (and I wouldn't think it would).
Yes it has a "Float Charge" capability but it is TOO SMALL to charge and maintain a full size car battery. You need the next bigger unit. This is for motorcycle and similar smaller batteries. The Schumacher XC6 can charge AND maintain your car battery. It is smart enough not to overcharge! You can leave it connected without a problem.
It will keep your battery at full charge. It has float charge and over
