This charger is much smaller than I thought. it was not fully charged. It works just like my old charger, no matter how low the battery is, it still takes a long time to fully charge the battery and I'm fine with that. The only thing that doesn't impress me is the length of the connection cables. As for the battery, I was able to find a place to install it while it was in my van. My van is an RV and the charger works better with my rear battery as I built the van to order and finding a place for it is pretty easy.
