It is a good idea. All batteries lose some charge on the shelf, so a top-up before fitting helps.
AGM: how it works
Compression inside the case is part of what makes glass-mat batteries so sturdy. Because nothing can spill, AGM batteries can live inside a cabin, a boot or under a seat. Keep AGM terminals clean and tight.
