Charging battery

[Alex28]

I just bought a new battery, and I put it in my bike, can I charge the battery outside while it's in the bike? I was going to do it overnight.

I forgot to add it's going to be -3 Celius overnight, I don't know if that affects anything.

Does the battery NEED charged? Do you have an charger that will safely allow you to connect to the battery while it's in the bike? I would think that low of a temp might make it slow to charge but can't say for sure since I'm a few clicks south of where it get's that cold.

-3°C thats not cold.
You do not want to keep a battery discharged for a long time in a cold climate(-20 -30 °C) because it will never hold a charge again.

But a battery will charge in a cold climate. I live in north of quebec and we charge battery at -45°C when required.

Anyway, usually when you buy a (new) battery they should be pre-charged. If your new one is not maby its a bad battery wich do not hold the charge(happened to me with a truck battery)

The battery I bought had to be semi put together, I had to put the liquid stuff in it, so it didn't come with a charge. I've left the new battery in the bike for a few hours and I'm going to start charging it tonight at 9pm and then unplug it in the morning at 9am, leaving it not plugged in for a few hours wont hurt the battery right?
