I got in my smart a little while ago to go to the store and it decided it didn't want to start today.

It's not cranking, I turn the key and I get a couple clicks and then it goes to beeping and flashing the single wrench and a -1 where the mileage is.

It was fine yesterday, no trouble whatsoever. It is 22 degrees F outside but I've stared ok on colder days.

Any ideas?

With the clicking noise, sounds like a dead battery. Got jumpercables or get a new battery

Also possibly pull up passenger floor mat and check cable connections are tight

Don't have access to a jump start, but do have a charger. Hooked that up directly to the battery and it went right into the charge cycle.

I tested it with a multimeter and showed 11.7 volts off and 10.5 in position 1.

11.7 is a little low, does it crank now? Were the voltage readings taken with the charger connected or disconnected? If they were taken with the battery disconnected, replace the battery. With just the accessories on in pos 1, a 1.5 volt drop is significant. How long was the charge interval?

But that wouldn't make it not start would it? Be kind of silly, how would you get it serviced if it won't move. lol
No THAT (the wrench) wouldn't do it, was just explaining what it was :rolleyes:

At 11.7 volts it's SHOT! :sorrysign:

Open Circuit Voltage Approximate State-of-Charge at 80°F
12.65 - 100%
12.45 - 75%
12.24 - 50%
12.06 - 25%
11.89 - or less DISCHARGED

I only just started charging after taking those readings. I'll be testing it again once it finishes charging.

The 11.7 was in position 0 (off).

Just finished the charge cycle and it started right up. Still can't get the service indicator to clear though. I know for sure it's early but I'll get it taken care of anyway.

Actually, that would be useful. Master chief, what's your source? Is that some newfangled ASE certified training or something? Because mine reports 11.3 volts in the mornings now whether it's 22 or 50 degrees. A month ago I could swear it reported 11.7, and I'm pretty sure it was 11.9-12.3 when it was new.

I'd better find a 34R battery soon huh?

I told myself I was going by Autozone for a load test tonight, but I got an early call home and my plans were derailed. I do have a trickle charger... I think I'll go hook that up for a bit tonight. It's gonna be under 30 tonight.


I found this reference...

I have had similar problems - waiting for the dealer to swap out original battery for a stronger one. It seems the factory battery is not strong enough for use in colder climates. Do a search on "battery" and you will find several people have had the batteries replaced. Guess the factory does not want to issue a recall and is handling the issue on a case by case basis. Many on this board are using trickle chargers or upgrading batteries to Optima red top 34R. When my battery is replaced (still waiting for a clamp to arrive from smart), I will post model # (I hear it is an Interstate model).

I put mine on a charger for about 10 minutes at 6 amps until it showed nearly done, then 2 amps for about half hour. This morning started at 11.7 volts. Yesterday - same time, same temp - it was at 11.1 volts. Maybe 4 miles isn't enough to charge back the energy used for one start cycle? I looked at the manual's battery section again and it does state that if you have lots of short trips you may need to visit the dealer more often to have the charge checked. Maybe I need one of those solar trickle chargers... 5 watts oughta do it, right? It's a small car. :)
