Wont start in cold

[Kai_kimura]

Went to start my 05 GS this morning I was getting the battery sounded low and I got a very loud "crank" sound. Then after that the battery just started clicking. Video:

Sealed batteries have this nasty habit of abruptly dying. No gradual worse and worse and worse as of old.
Cool.

Trick to cold starting is to let the battery warm up.

Crank for 5 seconds.
Wait 10 seconds.
Crank for 5 to 10 seconds.
Wait 15 to 20 seconds.
Try again for 10 seconds.
Wait 30 seconds to a minute
Try again

Usually you'll start before you get to the end of the list.
Using the battery a little causes it to warm up. When warm, it has more power.
Don't keep cranking until the battery dies as you may damage it. Go short bursts so the battery can warm up from use.

The vid looks like your in a garage. Have you considered a trickle charger daily with one of those short plug pig tails wired to your battery?

Remember that a good battery won't need a charger unless it sits for a couple months. A really good battery can go for a year.
However, if extremely cold, a trickle charger will keep the battery warm which being warm, it will naturally have more power.
