Battery Tender
In contemplation of an extended absence from home, I'm looking to buy a battery tender.
Questions: 1. One site states,"Optional cigarette plug allows you to charge & maintain your battery directly from your vehicle's lighter socket (only use if socket energized with key off)" Does that work okay for our 370Z in the 12v outlet? 2. Are these tenders safe to leave on when no one will be home for 3 or 4 months? Any problem with a power surge following a temporary power outage? 3. Is there a make or model tender that is made for or best for our cars? |
I have 2
One is on my z and one on my Harley. My Harley has it on year round I only take it off to ride then when I get home it goes back on. But to answer your question yes they are very safe b/c they charge the battery to full charge then turns off,and as the battery discharges it turns back on to charge it back to full. |
I call them trickle charger. The one my dad has is hooked directly to the battery. Works great. Never seen an issue with it in two years. Even for months. Not sure if it's good on a motor not to be ran from time to time though.

So for your questions. 1. I don't think so, but for a 4 month period, I would take the battery out of the car and put it on a charger. 2. Yes it's save, just put it on a stable place with nothing too close to be sure. 3. The Battery Tender is a good one. |

And it will not charge unless the battery gets below a certain voltage,plus it has a fuse in it in case of a power surge the fuse pops and saves the charger.:hello: |

I have a Battery Tender Jr. on my 67 Camaro. I leave the battery connected to the car, and I have the leads hooked directly to the battery on secondary terminals (optima battery). My car has set at some times for 6 to 9 months and I have never had a problem. Its a great product. Just remember to use some fuel stabilizer as well. Add the fuel stabilizer and then put a few miles on it to make sure it mixes well and gets all through the fuel system. I would NOT use one that connects to your cig lighter. Seems to risky and why run a charge through your entire car to get to the battery. Just my opinion, better safe than sorry

Thank you all very much.

I just wanted to mention that if you use a Battery Minder it will desulfate your battery after it fully charges it and keep it charged. Kind of a bonus. Also I should add that this winter I had it hooked up through my cig lighter and it was perfect. So much easier than connecting to the battery itself.
