Some of these AGM batt's say fully charged, just install. I would suggest using a 1.5 or 2 anp charger to top it off and make sure is is full. Take a volt meter and note charge, should be 12.3 up to like 12.7, slow charge it, and let it sit for a couple hours, ck your volts again, now you have a good starting point to monitor your battery. Would not be unusual for a hot batt to show in the 13'ns, then settle back to 12.3ect. For a couple bucks go ahead and add a charger pig-tail to the batt, tuck it behind side cover until needed then no need to remove seat to charge if needed. Further, add a volt meter to your system, (super easy& low cost), can monitor batt and system, running or not. My digital volt meter and on-off switch was less than $20, and works great!
