That FF (Simrad GO7) is rated for a little less than one amp-hour (950 mA-hour) but has a maximum power use of more like 1.6 AH, so if you use backlighting, GPS and a high energy draw transducer continuously, even a 12 amp-hour battery isn't going to be enough for a full day. A 20 AH battery will weigh a bit over 12 pounds (sealed lead acid). Does require a charger for small batteries (not a car charger) but is cheaper first cost than the seriously more expensive alternatives which take a different, special charger.
