Why We Upgraded Our Solar Batteries
It’s expensive to capture the sun (but worth it)
Sealed lead acid batteries don’t emit toxic gasses (because they are sealed). Our options if we were going to keep the cheap lead acid batteries would be to put them in a sealed box and ventilate them to outside of the van OR just breathe in toxic gasses day after day, night after night. We probably would have ended our trip with ears growing out of our elbows or something (prediction not based on science.).
Sealed lead acid batteries don’t require ANY maintenance. No checking water levels, no gassing, no dealing with toxic junk. Just set them up in right with the charge controller from the get go and enjoy your powered home on wheels! This is my favorite part about them. No time spent on maintenance means more time spent on fun things.
You can set them up in any position you want. If it made more sense for you to store them on their their sides, you could do that. We ended up putting them right side up, just like the old batteries, but flexibility in a small space is important.
There’s only one thing that I’ve found I don’t like about the new sealed batteries – the cost. We paid about $1200 for all four. Replacement lead acid batteries with the same specs could have been as cheap as $450.
But hey! $1200 is worth it not to have my girl breathing in toxic fumes. Money well spent.
