Civic 2004 battery replacement. Used one ?
 

Hello,

My civic 2004 hybrid battery is dying. It's been a month with error p1433. Now I decided to replace the battery but the problem is there no original honda batteries available.

So here are my options:
* new battery (panasonic), warranty for just 1 year, cost $2000.
* used honda battery, the dealer claims it's used for only 30k miles, warranty for just 2 months, cost $1000.

Which one is a better option? What things should I check if I went either one?

Thank in advance.
