is this a AMG baterry?

Hello, thank you for your question. No, the DP27MF is a flooded lead acid battery. Some do come in a maintenance free case but are still considered flooded. If you want AGM, here is a link to many that we have to offer. If you have questions please let us know and we are happy to help. https://www.battsys.com/catalogsearch/result/?q=27+AGM
