I still use lead acid batteries and "generally" don't care what brand they are. Gel cells do have some fine print about charging and maintaining them also. Check into that.
One thing I do know about lead acid is that they need to be "fully" charged before you hook them up to the truck or any load. I would never hook them up in the vehicle and think that the truck will give it a full charge. Putting a load (like starting) on the battery before it is initially fully charged will result in "setting" the battery and the battery will never perform as well as it could have. I don't count on the store to tell me it is fully charged, nor do I let them put a load test on the battery before they let me take it out of the store. This will also set the battery.
I take it home and charge it myself (usually 10-24 hours) before placing it in my vehicle. Always check the acid level on the battery before placing it on a charger.
