NPP ft (telecom) 12v 100ah vs. WindyNation 12v 100ah

[Nikki86]

Does anyone really know the difference between the NPP telecom 12v 100ah and a WindyNation battery (normal deep cycle)? They both have a 20h discharge rate and they both have great ratings for solar use. I' considering the NPP because it has a 2 year warranty.
I did call both companies and neither one was very helpful.

thanks anyone who can explain this.
