Detailed description

The BG-121000NB-M is specifically designed for electric trolling motor needs:


  • Maintenance Free - this is a Sealed Lead Acid battery which means there is no need to check and top up electrolyte levels.
  • AGM Technology - electrolyte is held in Absorbed Glass Mats between the battery plates ensuring maximum contact between the plates and the electrolyte for longer cycles and faster charging.
  • Deep Cycle Design - the Absorbed Glass Mat design strengthens the battery plates to minimize plate buckling during deep cycling or when heavy current is being drawn
  • Group 27 size - will fit most marine boxes such as the Minn Kota Battery Power Center
  • Any position orientation - no liquid electrolyte means you can place this battery on its side, at an angle or even upside down without any loss of performance
  • Low self discharge - less than 5% per month when stored at 68F (20C), less than 3% per month at 41F (5C)
  • Large Reserve Capacity - with a capacity of 100Ah this battery can power most trolling motors for up to 20 hours (at minimum speed)

If your application runs on multiple batteries, make sure to replace all of them at the same time or you will dramatically reduce the lifespan of the new batteries by mixing them with older batteries.

You have to install your replacement batteries in the same original configuration they came out and are required to use your existing hardware and cables to reconnect the replacement batteries when applicable.

It is your responsibility to verify the battery or batteries being ordered match the battery or batteries in your application prior to placing your order. Please check your:

  • existing battery dimensions (Length x Width x Height)
  • quantity needed to replace all batteries
  • voltage and amp hour requirements

Manufacturers may change requirements without notice. BatteryGuy is not responsible for incorrect orders - if you need help, please contact us.


Batteries, battery posts, battery terminals, and related accessories can expose you to chemicals including lead and lead compounds, which are known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to https://www.p65warnings.ca.gov.
