The Yuasa 900mA Automatic Battery Charger & Maintainer provides low-rate charging and long-term battery maintenance for compatible powersports batteries. Yuasa states that it automatically switches to maintenance mode after the battery reaches peak voltage and uses a 7-stage charging algorithm. It supports most 6-volt lead-acid batteries and 12-volt lead-acid, AGM, lithium and gel-cell batteries, making it especially useful for motorcycles and equipment that spend time in storage.
