Battery Tenders
I have two new RV Batteries and want to keep them completely charged. Stupid question I know, but here goes. What size battery tender do I need to get and can I just hook it to one of the batteries in...

So I want to take better care from the start with these two new batteries.
The first thing you need to do is get a little multi-meter so that you can read the actual voltages instead of guessing at things.
You can get a pretty good one at WalMart or Lowes etc. for $20 or less. You can get one from Harbor Freight that is adequate for about $7....or less on sale.
Edit: I see that you have that covered so......it is possible that they gave you the batteries in a discharged state and it might take several days of continuous charge to bring them up to near full.
Leave them on charge for about 3 days; then leave the battery switch ON with the charging off for 24 hours and see what the voltage is.
If this is a brand new unit and they gave you batteries that had been sitting around in a discharged state for months on end, they might be shot already.
