You do not say
which direction you are heading when leaving Grenada or what type of batteries
you are seeking.
You have three choices:
1) Buy from a local store such as Budget Marine or Island Water World and just swallow the price
2) Freight batteries from the USA using one of many freight shipping options – This will be lower than option 1 but require an agent in Grenada for YIT status and of course will take time.
3) Sail to another country such as Puerto Rico and buy batteries at Costco or West Marine. You can buy on-line and have them delivered to a store for free in PR (sometimes) – it’s only a 4 day sail from Grenada to get there. Some of the other islands also offer a good battery selection such as Martinique and St. Martin.
