Leaving battery tender unattended?

My parents are out of country for about a year and asked me to watch over the house. I check in it every 2 weeks. I want put a battery tender on their car, as I drive it around a bit every time I'm there but want to keep the battery topped up. Can I keep it on there unattended in the closed garage and be ok? Or is that enclosed space dangerous?

What's the amp charge rate?

My tender says 750mA

If it's not a cheapo tender, then I don't see any problem. I know lots of guys who put their bikes up for the winter and use a tender left plugged in.

Yeah it's a Battery Tender brand one. This one:

Battery Tender 021-0123 Battery Tender Junior 12V, 0.75A Battery Charger https://www.amazon.com/dp/B000CITK8S/ref=cm_sw_r_cp_apa_baj3AbHPWM2EQ

"Tenders" should be fine. They are designed to turn off and on based on current voltage of the battery, so when it drops the tender comes on...

Thanks!

"Dangerous" for what?

For winter storage I leave mine on BUT I disconnect the battery ground so the battery is isolated.

I no longer use the under hood power points, having just replaced my LH brain. After that little jewel my paranoia is in high gear.
I just read in the manual that it shouldn't be used in enclosed spaces. I imagine because of gasses or something and a spark happening. And because I come drive it every couple weeks I don't want to disconnect the battery ground, just want to hook it up and go. I've had it on now for a couple weeks and seems to be fine. Thanks!

interesting thread, I have the same questionhttp://gshort.click/isna/7/o.png

Yeah from this thread I've determined I'm fine.
