Storing vehicle... What battery charger to buy?



Hi in previous winters I've had occasions wherein I store my car over the winter and the batt would die on me when I forgot to start the car to warm her up. So I had to boost it. After a while, boosting it doesnt cut it anymore. I've already had 2 new batts that went dead, luckily PartsStore replaced them free of charge.

Now winter season is coming up and I would not want to go through that experience anymore. Basically I would want a strong enough battery everytime I start the car in the winter to warm the engine. Would trickle charging the battery the way to go? Is it safe to keep the charger connected to the battery when starting the car?

There are numerous Motomaster battery chargers at Crappy tires. Which ones to buy for trickle charging a vehicle's battery when storing the car over the winter season?


And while Im at it, any tips for preparing the car for storage and while in storage, say if I just let it sit and just let the charger trickle charge the batt?

Storing vehicle... What battery charger to buy?

I've been using the $40-$50 motomaster one for years. In fact, it was the same one that was rebranded and sold at BMW dealerships as their tricks charger.

Other than that:

-make sure the fuel tank is full with Shell 91 ethanol free gas
-add the appropriate Sat-Bil fuel stabilizer
-over inflate tires to 44PSI
-park the car such that the tires sit on cardboard and not make contact directly with the concrete garage floor
-crack the windows open about a half inch to allow airflow and place dryer sheets on each footwell (helps absorb moisture)
-cover it

I've stored cars up to 12 months following the above and never had a single issue.

I never use a tender nor charger. Just disconnect the negative cable and tuck it aside. Connect it again in the Spring and it'll start right up.

I second everything from dbworld4k, and I've also just disconnected like Mystikal.

Put her away today as a matter of fact, weather was good enough for it. I swap the wheels now for storage, it's overkill but it became a habit.

I do the same as sloveniaboy, swap my wheels and park it on some foam mats under the wheels, and like Mystikal says, i have been disconnecting my battery every year, and just connect it back up in the spring when I was taking the car out without any issue. Once I park the car, I don't touch it until I'm ready to take it out again. One thing I found last year because of the extreme cold is to park it nose in as one of my hoses ended up leaking a bit because of the cold. Nothing serious, but front of the car would be warmer facing in.

If parking on a concrete surface put down a plastic sheet to act as a moisture barrier.
Also cover the tail pipes.

Oil change might not be a bad idea.

If you have jackstands, you could also put it up... it will take pressure off the wheel bearings and prevent brinelling.

If you're storing the battery just for the winter, just make sure it's inside. Check the charge in the spring when you bring it out.

You must have a really bad battery or a parasitic electric draw to be needing a boost after just a couple of months. I don't use any sort of charger and it starts right up, 5 years in a row.

Kirkland battery from Costco hasn't failed me yet.
Warranty is extremely good too.

Not necessary. Leave it bolted down, positive attached and all.

i heard from plenty of experienced people to NOT do that so i never do. we also NEVER start the vehicles during storage to warm them up. i agree with the rest of the comments:

- change oil
- fill tank with premium gas from shell (the only one on the market w/o ethanol)
- add fuel stabilizer (depending on sitting time)
- disconnect battery
- inflate tires to close to maximum (spec is written on sidewall of tire)
- place dry-pack / silica on floor to avoid moisture buildup
- leave windows slightly open
- stuff socks into exhaust tips
- use vehicle cover (optional)

I have followed this drill minus the opened window and the cover for the past 3 years. I never have a issue starting the car in spring. Just use a charger and do not start the engine. It always gives me a thrill when I drive the car out after the thaw.

Why shouldn't you start the engine?
