New batteries
Haven't seen any recent messages on this topic, so...

Need to replace the coach batteries on my 99 MB. I'm leaning toward the original Trojan T-105's. I was quoted $160 each after core charge by a golf cart company. No solar on our rig.

I see also that there is now a T-105 Plus which looks the same as the original 105, as well as a T-125 (and 125 Plus) which are the same size. Lastly, I see that Trojan now has it's own "hydrolink" watering system which looks a lot like Flow-Rite system that I've had for many years and may need to be replaced.

Thoughts on cost and which batteries to buy would be appreciated.

I recently found a golf cart place here in south Orange County (Laguna Niguel area) who will sell new 105s for $125.  I don’t know anything about the 105+ but would like to hear about it.  When my batteries go bad I may go to Lithium Ion if I can afford it.  Then again, I am so cheap I will probably stay with the original 105s.

Why not go with AGMs? You can forget about that constant watering PINTA and they are not as expensive as Lithium!   ::)

I haven’t completely ruled out the AGMs.  Just worried about the weight when I’m trying to install.  Sounds silly I know.

I doubt if there's much difference in the weight, although I admit I've never checked. I always let the other guy, such as AM Solar, do the heavy lifting.   ;D

I switched to Lifeline AGMs several yars ago and will never go back.  They fit right into the same tray as my previous Trojan batteries and require no maintenance.  The GPL-4CT is 4 lbs. heavier than the Trojan batteries. Easy install. At about $300/battery, they are significantly more expensive however.

Did you keep the same converter/charger?  Just drop in replacements using 2 6v AGM batteries?

Yes, I use the same converter/charger that came with my RV.  I can't remember all the details at the moment but I had to change a setting in the solar charger as well as in my battery monitor.  Other experts on the forum can chime in on that.

AGMs are about twice as expensive as T-105s and the only major advantage, for our purposes, is not having to add water a few times a year.
WIth a remote watering system, adding water is 5 minute job.
It probably works out to getting paid a hundred dollar an hour to water the batteries. It's only money.
