: Features a redesigned Update Manager to handle the frequent data refreshes required to keep the catalog current.
The "Xtr3m3" series introduces amorphous carbon to the negative active material. This solves the Achilles' heel of AGM batteries: partial state of charge (PSOC) operation. If you run your fridge and lights all night and only drive an hour the next day, standard AGMs will sulfate quickly. The Etka 8.3 Xtr3m3 can handle PSOC for weeks without damage, making it ideal for solar-only setups.
