Chuck:
Sorry not to respond earlier. Just got a chance to look at messages. Earthquake took out power for a couple of days and wifi just dumped about 200 messages onto my phone. I purchased my Trojan SCS 225 Group 30H batteries from Battery Giant, 1 Calle Acuarela, Suit 102, Guaynabo PR 00969 ( a few miles south of downtown San Juan), Javier (787) 509-0109, main (939) 205-4444. He had to special order them (not stocked) and it took about three weeks for them to come in. I just timed it so they were there when I arrived back from the US. $240 each total including the 11.5% tax on everything here in PR. You will need a car to pick them up. Perhaps they would deliver, don't know as I didn't enquire. It is about a 15 minute drive from the San Juan Airport to Battery Giant, south of the city. I just got them with the rental car upon arriving in San Juan and headed to Puerto Del Rey.
Let us all know if you find something better.
