Battery Dead problems of the 2002 Honda Odyssey

A couple weeks ago as me and my 2 toddler sons were going down the road. The vehicle had what seemed a power surge and taillights went out and power went low radio stopped and doors unlocked. Luckily we were close to home I got new fuse for lights radio said error but music didn't matter the next day I had to jump it to got work but seemed ok. The next few weeks I dealt with doors locking and unlocking. And one morning came out both doors were open. I didn't let boys ride after problems escalated one day doors stopped and got stuck in middle when they were getting out. It I replaced some fuses and everything seemed ok but most days battery felt work when starting. I went to get boys and I'm glad I didn't have them when it died in middle of road smoking I got it in parking lot. Called father and we took battery out to go get a new one. The battery was swollen water and acid spitting out like it was going to burst. New battery installed and drove it maybe 5 min back home. Thought well it was battery whole time. Went inside to open easter things with boys I walked outside hour later and smelled electrical fire smell bad there was smoke coming out of hood not aloft but battery was dead. It seems like something keeps pushing power through the different elements causing them to short. If you look up on internet dead battery 2002 Honda Odyssey nothing but story's of power surges making vehicles loose power burn out the list goes on and on. What if my boys and I had lost power on highway. Or door decided to open I don't know the problem but every story talks of it. Kids lives in these vehicles are in danger. Please help. I say it could easily be accidents I was just Smart enough to avoid them by disconnecting paying attention and be prepared. Not everyone is like me most hop in and go now I have no vehicle no help and think of all the other children in these van's. Thank you.
