Don't use a trickle charger unless you plan on monitoring it daily. Trickle chargers don't ever turn off. Get a charger that goes into float mode (stops charging and monitors voltage).

I keep my batteries plugged in year-round. No need to take them anywhere other than their designated placement. The beauty of plug-and-play-and-forget.

Battery tender = connect it and forget it... until spring.
Done with Battery Tender due to their warranty service. After being a loyal customer for eight years, they won't honor my older warranties.. . Going to another brand...

+1 on a trickle charge. Ever leave a pan of boiling water on the stove forever? Same principle...

Sorry to hear about your bad luck with Deltran.
I have 5 Battery Tenders. Two of them are the older original Battery Tenders and never had a problem with any of them. My most recent is a Jr. I bought last year.

The battery charger type and size should be determined by the specific application. One size definitely does not fit all.
Fisherman running a heavy trolling motor, fighting a wind, all day long, with a large capacity battery bank, have been dialed in on battery charger technology long before the advent of wakeboats. Just follow their lead if you have a large audio system, with a large house battery bank, and use the stereo for long durations at rest.
A minimum amperage smart trickle/tender/minder/maintenance charger is fine if you have a weekend car, tractor, motorcycle, ATV, UTV, etc, that is placed into storage with a fully charged cranking battery.
However, if you have a large capacity deep cycle battery(s) that is placed into storage with a deep discharge then you need a smart 3-stage charger with enough (but not too much) current capacity to excite the battery in order to counter the effect of sulfation. A charger using pulse technology may not need quite as much current capacity to do the job.
An ACR/VSR will have an impact on your dependency on a shore charger.
Having even an undersized charger is better than no charger at all. Batteries self-discharge several percent per month. Battery degradation is accelerated in a discharged state.

My uncle had a battery tender on his new Porsche a few years ago and the battery exploded. He couldn't get the hood open with no power. Had to tow it 250 Miles and have the engine professionally cleaned $1,800 bill. No more tenders for him.

I think your uncle had a trickle charger and not a battery tender from Deltran or CTek. There is no way a battery tender caused a battery to explode. Also you can open the hood of a Porsche with a dead battery by going to the fuse box. The instructions are in the owners manual
