small charger for AGM?

I have a friend who just purchased a couple of 18ah AGM batteries and needs a good charger to keep them healthy. They are 12v each and will be used to power a 12v CPAP machine overnight in the event of local utility power failure, so sort of a poor man's UPS. Can anyone here recommend a reasonably good, intelligent 3 stage charger for a battery of this size? I think both batteries will be wired in parallel and the charger will be plugged into a standard 120v wall outlet, this is not solar related (sorry!).  I tried the 'bay but get deluged with hits and didn't know how to filter them, there's so many differents ones and I have no idea which ones are good and which are flakey. Probably all are built in china, but I don't know their track records...

my thanks and aloha,

    Look at NOCO chargers, their site has all the models and they are for sale all over the internet.  I use them as tenders on all my stuff that sits.  The support site has all the charging profiles and they have a setting for AGM batteries.
