Your boat's batteries and the power they store are one of the most important resources on your boat. Running out of power at best can be bothersome and at worse dangerous. With all manner of new equipment constantly being improved and upgraded on your boat, do you know if your battery supply is still sufficient? Do you know how long your batteries will last in all your different boating scenarios?

--- Boat Battery offers the solution! ---

Boat Battery is a unique App that allows you to calculate your sailing or motor boats DC battery usage in different scenarios to enable you to adequately provision your battery bank and identify potential problems!

Use Boat Battery to:

- Calculate how long you can be at anchor before your power supplies run low! (and then graph this out!)
- Calculate how long can you sail before your batteries run out.
- Calculate your ideal battery bank size!
- Search our community database of marine electronics to find out the draw of new electronics you may be considering purchasing.
- Search our community database of charging devices, including wind, solar and engines.
- Use our knowledge bank to answer common questions about marine electronics.

Use Boat Battery to experiment with what-if scenarios

- What if I fit a wind turbine, how much longer will this give me away from port?
- What if I install a new GPS with a bigger screen?
- What if I fit a fridge into my boat?
- What if I increase my battery bank size?
