Using different flooded batteries in parallel
I just bought a new-to-me travel trailer. It's a 1973 21 foot coachman travel trailer. I'm looking at the electrical system and it came with a deep cycle flooded battery. I'm wondering if I can take my deep cycle flooded battery from my previous travel trailer and wire it in parallel to the existing trailer battery to increase my available Ah? I realize everywhere tells you to only parallel the same brand batteries, bought at the same time, but my understanding is this is because your system will only be as good as your worst battery. Are there any safety concerns?
The two batteries are different brands, one is about 3 years old and the other is one year old. They are both flooded however one has a higher Ah capacity. Are there any considerations or limitations I should be aware of?
My thoughts are, even though it won't be as great as if the batteries were the same, I'll still be increasing my overall available Ah.
I won't do it though if there are safety concerns or I could damage my charger or other components of my system
Thanks!
