Yes, if the generator is not going to be used regularly or placed in to storage, the battery should be removed and periodically attached to a battery charger/maintainer. A 12V intelligent multi-stage charger capable of delivering 1.1 amps is recommended. The Battery Tender Plus(SKU#102460) is a recommended unit by Honda Power Equipment.
