Hello! Long time lurker here. I have a group of gel batteries that see occasional use and am looking=20 for the simplest way to keep them topped up and ready for use. I'm thinking of having a single float charger which I can hook these=20 batteries to in parallel (after charging them conventionally) and then=20 leaving them. Can I just connect them in parallel or should I have diodes isolating=20 each battery? Also, can I mix battery types? I have a car battery sitting in my garage=20 which could benefit from storage on a float charger. Thank-you!
