I am looking for a battery charger/maintainer I can plug in whenever I plug in my frost plug heater in the winter, which is often. Just to keep the batteries in top condition. I was thinking the battery tender waterproof.
Good idea?

 

I've seen it several times. You want seperate plugs. Leave the block heater on its own cord.

Is there a better charger than the battery tender waterproof?

 

I would likely lean towards this one:

Check out the battery minder 1500. I put one on my truck and it works great, truck starts like a champ now like it did with brand new batteries. I usually don't drive the truck Monday through Friday so it sits a lot and it has the typical "gauge cluster drain".

The unit plugs in in the garage and the 12v cable runs to the truck not 110v as with bigger chargers. I ran the wire through the wall and the truck end in the bumper by the driver's side tow hook. I got mine at Northern tool and saw that its still on sale 42.99. They even sell a 25' extension cable for it if needed. I went with the Battery Minder as its a Desulfator the others I looked at were not.

 

That one is 24 volt. they have a 12 volt waterproof for $35

 

Oops just saw that. But wont that make my truck go twice as fast if I charge my batteries to 24 volts?

 

In cold weather, I had a voltage drop, fried my fuel injection computer. $900. What about a battery warmer?

diverseth, I had that same sign on the back of my house during construction. My A-hole neighbor took me to court asked that I remove it, so I put it out front by my gate, he gets to see it more often there.

 

As far as I'm concerned, any of the batter minder/tender ones will work great for this application. It's probably overkill to have it charging the battery every cold night, but it won't hurt.
One option is to just hook up the ring-type leads to the battery on a more permanent basis, and to bring the actual battery tender out with you when you plug the truck in. I've done that. I have never mounted mine in the truck, I'd be worried about the vibration, salt, water etc being bad for it.

between my three vehicles, it seems like I have a charger on at least one of them every time it gets cold. Right now, I've got a stupid Daewoo that has an alarm problem, but the battery tender solves it.

 

I just bought the Battery Minder 1500 and im very happy with it.I leave it hooked up 24/7 when the truck is not in use.
