New XS Power customer. Resting voltage 12.84. Do I need to charge it?

I don't have a charger and didn't know until now that I needed to charge it. Being Crucial on the paper seems important but says you can use it if it's above 12.6v. Hmm.

12.8 is normal resting voltage for XS batteries in my experience. If it's going to be sitting for long periods of time without use/recharge, then yes, put it on a charger to keep it fresh

You should definitely charge it. A ctek charger can be had for pretty cheap. You're going to need to top it off from time to time to maintain it. 

 

I just got my D3400 earlier today and it had a resting voltage of 12.8. Threw it on the charger and now it's resting a little over 13.

I have had a XS power D3400 under my hood that I replaced factory battery with and never charged it aside from alt, should I be ????
