Am i able to hook a trickle charger on the post under the hood? i am unable to get to my battery due to the sub enclosure that i have. just wondering thanks!! i have an 09 ss/tc if that matters

 

I've had an issue with that charging post, I accidentally killed my batter twice, and when trying to boost that post didn't work, and it took a charger.. DAYS (not literally) to re charge my batter from that post...

yet when I did it direct to the batter (jumpers) it started right up, and charged in a few hours direct to the battery as well

 

Its best to do direction on the battery, but I don't see why it woudln't work to recharge it from that post. The alternator does when you drive it.

 

yes u can. ive charged a cobalt from it

 

okay i just want to charge the battery during the winter months while its sitting in the garage so the battery doesnt go bad and i have a trickle charger so just making it safe that its okay to do

 

ah, well I guess if you're doing it over long periods it would be best to do it from the post, I always thought you removed the battery when storing a car... no?

 

its a manual.... push pop it to 2nd gear profit

 

i would love to take my battery out and charge it that way, but i got a custom sub enclosure that takes up my entire truck and i would have to take it somewhere to be taken apart so i can get to the battery lol

 

lol right^ missed the custom sub stuff

 

yeah thats the only problem, and the battery is already dead, so i am just going to trickle charge it off the posts under the hood until winter is over!!!!!!

 

your best bet for that is to completly REMOVE the battery. DO NOT place it on any cement. The cement and the battery are chemical oppsite and it can neutralise the acid in the battery.

Best to keep the battery someplace warm too. Maybe the office in your house?

 

Also do not place it near NiCad batteries for the same reason

 

This was true when batteries were made from wood. No longer the truth.

 

Too much torment on this board - give me headache......

I bought a solar charger, and I've charged off that post no prob. If you're in an area that gets a decent amount of sun, this can be an easy and free way of keeping your batt charged.

Otherwise, a trickle charger will charge just fine off that post. One caveat, however; I would be careful of the "de-sulfating" trickle chargers if you're using them - they have an intermittent high voltage cycling that is supposed to de-sulfate a battery with bad charge; if you have one, it can do bad things to your electronics unless you disconnect the battery from the car, unless you disable it. I have a duracell 2A/trickle charger that I've used on all my cars which doesn't de-sulfate a battery. I also have a "battery tender" which de-sulfates, and I NEVER use it on any battery connected to a vehicle electronics, for the reason that it can do cruel things to any electronics connected to that battery......

 

Yep. All desulfating is, is a controlled overcharge. Also known as equalization. Voltage can go as high as 15.5-16 volts. Definitely not recommended for it to be connected to the vehicle.

 

Should be fine, though I DO suggest to go directly to battery with trickle chargers.

 

Um, Don't think batteries ever were made of wood...
Clay pots on the other hand...
Baghdad Battery - Wikipedia, the free encyclopedia

 

Batteries used to be made from a wood case and glass. When you would put the battery on the floor, it would pick up the moisture, the wood would swell and crack the glass causing acid to leak out

 

^^^ batteries are Josh's business. Hard to find a fault with anything he says in this respect, he is the source!

 

We'll I have a battery tender trickle charger hooked up to the post under the hood. So should I be okay to leave it hooked up ? Don't want to wreck something on my car

 

So whoever made the custom enclosure wasn't aware of the battery/spare being below the trunk carpet? You'll have to replace the battery eventually.

 

Yeah we'll they have to take the enclosure out come this spring to put my coilovers in. But no didn't think it through all the way lol.

 

you will be fine with a decent trickle charger hooked up under the hood, (use a decent ground,) that turns off and on periodically. Ideal.

 

It is perfectly fine. I use a Battery Tender with the quick connect that is installed under the 12v post, been OK for me

 

I noticed I didn't exactly write clearly on my other post (brandy may have had a role in that....) I don't necessarily think its a problem if you connect a desulphating charger directly onto the battery at the terminals while its in the car - after all I'm pretty sure Deltran went through a lot of pains to ensure that their charger wouldn't go all hinkey if its was hooked that way. I would be concerned that the charger algorithm might be affected by the introduced distance/loss by using it on the post - after all it monitors voltage of the battery to determine charge mode, and if you have an introduced voltage loss as a result of that distance, who knows that that thing will decide to do!
