Deep cycle group 31 AGM battery, choices

[simonfraser]

for house low Ah discharge only - not starting - winter use in the UK Essex
3Ah daytime, 1.5Ah occaisionally overnight, going to install a pair as bigger capacity too heavy to lift and install
poor access, no topping up on a regular basis, so AGM

Trojan 100Ah

Power Plus 130Ah

massive difference in cost, buy cheap buy 2x ?

This is really just a duplicate of your other thread Simon. I told you there, for your stated use, bog standard sealed lead acid are perfectly acceptable.

There is no advantage for you having deep cycle and no advantage having AGM, so deep cycle AGM is just a total 100% waste of money.
