Group 24 Flooded to Group 31 AGM
Hi all, We are going to sign for our new toy hauler tomorrow and I inquired about upgrading the batteries that come with it from the group 24 flooded to group 31 AGM and as part of their quote, the...

Scam proofing
Demand a detailed list of exactly what their work will cover. Just writing "larger wire" is a scam. "Install 12 feet of 2 gauge wire from charger to batteries" is considered in detail.
A service writer can complete a detailed pro forma invoice in 5 minutes.
If they decline to do a pro forma invoice, then you have gold-plated proof you are being scammed. They can use hundreds of reasons for denial. Every last one of them is 100% B.S.
I must have completed 400 pro forma invoices in my 40 years of work. I had numbered special invoices titled PRO FORMA INVOICE
Keep in mind, the addition of a large DC to AC power inverter will demand huge cabling. But this is an add-on.
If you plan to keep your rig for at least 6 years, it may justify purchasing the sole deep cycle AGM brand on the market CONCORDE LIFELINE. You would be paying for a vastly increased number of battery cycles.
But it comes at a cost: You have to follow Concorde's maintenance instructions.
Myself, if I were in your shoes and decided to use expensive AGM batteries I would have just two chargers aboard. A Power Max 100-amp model, voltage hard set at 14.4
And a two or three amp temperature compensated battery maintenance charger.
Unless a battery is sitting at 110F permitting 14.4 volt charging for as long as five days 24 hours a day will not hurt a good quality AGM battery. So maintenance is not complicated like the recipe for baking a cake.
Charging correctly is simple. Let 14.4 volts rip until charging amperage drops to almost 0. In the case of a 100 amp hour AGM, the number is 1/2 ampere. Then switch to the maintenance charger.
Reminds me to go charge my Lifeline that has not seen a charger in almost 2 years.
