The whole idea of a battery tender is that they will NOT destroy the battery by overcharging and breaking down the electrolyte. You will get NO fumes other than an extremely tiny amount of water vapor from a battery on a tender/maintainer.
Which battery tender is preferred? the CTEK or the Deltran?
I'm a cheapskate so I bought (several) Schumacher maintainers at Walmart. They were $19.95, now I think $23. They always worked perfectly.
They also carry a B&D maintainer for under $20.

Actually I have heard those Battery Tenders made by Schumacher are pretty good even though sold at Walmart.
Using a maintainer can easily double and possibly triple the life of a battery. The difference between the most expensive and least expensive is not significant. The smaller (lower the current), the better. It is a maintainer, not a charger, so how fast it can bring the battery up to full charge should be unimportant. I have a couple of Battery Tender Jr.s that have worked great even when left on an unused car for several years continuously.
I'm in with the cigarette lighter, across the seat and out the drivers door with the cable in the divit in the sill {almost like it was put there} and shut the door.
I have been using CTEK's for years. My 07 will be 9 years old January 2nd and it still has the original battery in it. There has been no hint of its demise as of 10 days ago when I drove it. I have also used a Battery Butler in the past with great results. Hood is closed, car up on lift, there is plenty of air circulation with the hood down. FWIW.
*my results are not the typical tender users results. I am a professional, do not try this at home kids. Adult supervision is suggested...

Mine sits with the hood closed and cover on all winter, no problems ever.
What he said. I hook up to fuse box & ground & run the cord to the trickle charger under the car,
snaking it thru the gap next to the engine. After the engine fully cools
of course.

Same here. They seem to work fine. Did buy a cigarette lighter adapter however. Find that more convenient than raising the hood.

Did mine this way, stays hooked up just have to plug and unplug it into connector under hood. Got this pic from another member.
The reason for the tender is to save your battery's life while your car sits there sleeping. The same goes for the batteries in your "older" cars.
older cars don't have the draw on the battery that the newer ones do, they can be on a tender without being hooked up. when we go to Arizona for a month i keep a tender on my DD while we're away also
