It arrived at the house in excellent condition. Job we'll done. So far, the battery packs plenty of power for my trolling motor needs. Review: Should have gotten them sooner. Worth every penny. - Terrific with my Minkota 55 and my too heavy 15ft aluminum boat. Great power, lasts longer and depletes less and charges more quickly than all past batteries. The batteries that I have been looking for. Addendum: 6 stars!! The boat sank. A week later, both batteries were fine and the Minkota worked fine while batteries and motor were still underwater. While not recommended, it is an amazing indication of the quality and durability of the batteries and motor. ## Features - Electrolyte Suspension system VMAX tanks utilize an electrolyte suspension system consisting AGM (Absorbed Glass Matt) of a high porosity that totally absorb and contain the electrolyte; No silica gels or any other contaminants are used - Heavy Duty Grids: VMAX heavy duty lead tin alloys provide an extra margin of performance and service life in either float or cyclic applications, even after repeated over discharges - Maintenance Free Operation: There is no need to check specific gravity of the electrolyte or add water to VMAX tanks during float service life; In fact, there is no provision for this type of maintenance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0042L7DZ8 | | Battery Capacity | 120 Amp Hours | | Battery Cell Composition | Lead-Acid, AGM | | Battery Type | Lead-Acid, AGM | | Best Sellers Rank | #226,253 in Health & Household ( See Top 100 in Health & Household ) #749 in 12V Batteries | | Brand | VMAXTANKS | | Brand Name | VMAXTANKS | | Compatible with Vehicle Type | Boat | | Customer Reviews | 4.5 out of 5 stars 154 Reviews | | Item Dimensions D x W x H | 6.8"D x 13"W x 8.8"H | | Item Weight | 75 Pounds | | Manufacturer | VMAX USA | | Manufacturer Part Number | VMAX MR137-120 | | Manufacturer Warranty Description | 1 year | | Model Number | MR137-2000 | | Number Of Cells | 6 | | Product Dimensions | 6.8"D x 13"W x 8.8"H | | Terminal | Marine Terminal | | UPC | 804879255352 | | Unit Count | 1 Count | | Vehicle Service Type | Boat | | Voltage | 12 Volts | ## Product Details - **Battery Capacity:** 120 Amp Hours - **Battery Cell Composition:** Lead-Acid, AGM - **Brand:** VMAXTANKS - **Item Weight:** 75 Pounds - **Number Of Cells:** 6 - **Product Dimensions:** 6.8"D x 13"W x 8.8"H - **Terminal:** Marine Terminal - **Unit Count:** 1 Count - **Vehicle Service Type:** Boat - **Voltage:** 12 Volts ## Images ![VMAX MR137-120 AGM Sealed Marine AGM Battery 12V 120AH for 50lb -110lb thrust Minn Kota, Newport Vessels, Cobra, Sevylor and other trolling motors.

And if so did pick the right batt., thnx.** A: Completely depends on the load on the inverter. But, if you use 2000 watts constantly, expect the battery to last maybe 20 minutes and will also get pretty hot. Use two or more of these batteries if you are going to overwork them. **Q: What thread is the bolts on this battery?** A: M8 **Q: Trying to fit these in tight spot 9.5" and height is important. Is it 8.8" to top of battery or top of lugs (that would add 1/2"), 8.8 or 9.2 ?** A: Measurement of 9.25 to the top of the (bolt) lugs without any terminal connections. Hopefully that answers your question ## Customer Reviews ### ⭐⭐⭐⭐⭐ Battery called the tank *by L***Y on June 30, 2025* I was very pleased with the packing of the battery.

Great power, lasts longer and depletes less and charges more quickly than all past batteries. The batteries that I have been looking for. Addendum: 6 stars!! The boat sank.

Use this in conjunction with my starter ... *by D***Y on March 14, 2016* Awesome battery. Use this in conjunction with my starter motor. Spent the night on the boat and ran the dock light all night long. Also ran fish finder/gps withno issues. This is a very outstanding battery and as a matter of fact, I am purchasing another to add a third battery. There is no doubt that I will have too much power after that. You cannot go wrong with this battery. Just be prepared for a workout because it is extremely HEAVY. ## Frequently Bought Together - VMAX MR137-120 AGM Sealed Marine AGM Battery 12V 120AH for 50lb -110lb thrust Minn Kota, Newport Vessels, Cobra, Sevylor and other trolling motors.
