I'm an advocate for regularly checking on any electronics that are continuously powered. I would advise that your experience with a BT branded maintainer is not necessarily indicative of an issue with that brand - the same risk applies to any of them.
Sure. But in terms of checking on these things, they've reached a point where the low amp tenders are cheap enough that I'd argue that "lake testing" applies after ten years or so.

As noted in a different thread, the battery in the 987 appears to be fully dead - I can't get it to start with a charger or anything. I haven't bought a battery for a car in ages - does any brand work or should I look for something specific?

Regarding the trickle charger, the closest electric outlet to our garage spot is at least 70 feet away so that's not an option. My plan is to get a disconnect for the battery like I have in the e36 - just means I need to leave the front trunk unlatched which is fine.

Any brand should be fine. Just get close enough in specs.

These days, I mostly buy Costco Interstate batteries. Unfortunately, they did make their warranty worse, but the exchange process is so much easier than most of the parts stores. No, I don't want to wait a day for you to test it and come back.

Thanks! I'll probably just use one of the online "choose-your-vehicle" things and see what it spits out.

The one thatís in there came from AutoZone; you donít have to do anything special to replace it.

And 70 feet is a long distance but a trickle charger doesnít draw much power. You could easily get a 100í extension cord and plug it in. I think I ran a 50í cord when I was trickle charging it on my patio.

probably a stupid idea, but could you put one of these outside your garage closer to where the boxster is?

The idea of a disconnected battery and a closed trunk would scare me (I could totally see a wife or kid walking by and closing it thinking they were being helpful).

Thanks Joshes. Both great ideas but the spot I rent in the city for the Boxster is in a subterranean parking garage that is part of a condo building. The parking spot is in a relatively remote part of it but the outlet is right near the door where people enter so having a cord run over there seems unlikely to work. The nose of the car is against the wall so leaving the trunk cracked isn't a huge deal, and the fuse box charger trick works if I'm in a pinch.
