did I ruin this newish battery less than 6 months old , it was replaced under warranty that started 3 & 1/2 years ago so it's out of warrenty now.
I don't drive this trailblazer much during none warm months so to stay ahead of the battery drain, now a normal drain I can leave the car for over two weeks and still crank her up..
I connected a 18V solar panel it's the size of a sun visor.https://shop.solarpanelsvenue.com/sh...ttery-charger/

I plug it into the cigar lighter when it's plugged in there is a green LED on the plug I assume this indicates that it's on and is charging the battery.

connected the panel couple weeks ago yesterday the battery was drained down to 1.1 V DC and wouldn't start car. I believe the green LED actually drained the battery.

I've read that anything below 10V DC the battery is ruined is this true or false.

last night I removed the battery and connected my charger https://www.cabelas.com/product/Cabe...12&WT.tsrc=AFF. weird that it didn't start charging but did start conditioning for about 1 hour then started charging.

my charger is a marine boat type charger after it determines the type of battery it chooses it's mode blue for condition which usalley occurs after charge. green for charge however last night it when to blue then to orange never sean organe on previous charges.
anyway this morning the battery mearsured to 13.2V DC reinstalled it started the car and the amp needle was way over in the charge area will this stress out the alternater should I continue to charge/condition w/ charger before driving the car?

can I trust this battery to not fail?

it mite be time for a portable jump box. please suggest. Thanks for advice TB

 

No your green LED didn't drain it. If it's a sh*ty solar panel then it will drain the battery when it's dark out. The battery might be damaged a bit but not necessarily killed. You'll just have to use it and see.

 

it mite be time for a portable jump box. please suggest a decent smaller one

 

a lead acid battery can only take a limited number of deep discharges before its damaged. At this point, it may have reduced capacity but still be fine. Fully charge it for 8+ hours and have it load tested or conductanced tested. hopefully it didn't freeze.

a maintainer is one option. for my stored car; I fully charge the battery every 3 weeks...6amp charge rate overnight.

manufacturers require dealers to charge unsold vehicles every 30 days to maintain battery warranty on unsold cars. I use that timeline as my charging guide.

 

checked battery it's at 12.2 V DC and started the car.
I think I've been lucky w/ my lawn mower and boat start batteries.

a friend of mine told me you need to buy a new battery every year for each boat and mower, both are actually from 2 years ago the boat wasn't used much this past year but still starts engine.

I was charging/conditioning the boats like every 4 months or so. never recharged the mowers though.

I was thinking the LED was draining the battery and the solar charger really it's a maintainer should be hardwired directly to battery to avoid the LEDs drain.
I purchased the solar maintainer hoping to stay ahead of the parasitic drain I had remember.
I've found the drain. hate to admit it was the backup camera I now really don't need it anymore backing up the G360 w/ hatch up is good enough to connect hitch.

I'm wanting to install some house marine batteries to power a 12V DC frieg in my 24' cruiser
I'd like to install inside cabin but have been talked out of that plan because if the battery ever gets overcharged even sealed expensive batteries expel explosive fumes w/ the slightest spark will cause an explosion. Thanks TB
