Using it day to day: practical tips
A caravan with a motor mover asks for big bursts of current. Fit a fuse close to the battery on the main positive lead. Storing a bank half empty in the cold costs capacity that never comes back.
What AGM means for you
Lead plates in AGM batteries are often slightly thinner than in flooded types. Premium cars with lots of electronics usually come with AGM from new. If the original was AGM, the replacement should be AGM too.
