Mighty Max Battery 12V 35AH SLA Replacement Battery compatible with Minn Kota Endura C2 - Trolling Motor

This battery worked well with my kayak trolling motor, a 30 lb. thrust MinnKota. Small size and weight makes it manageable. I've used it exactly once as of this writing, so I cannot attest to the longevity of the battery. First use was on the water fishing about 5+ hours. Obviously I did not run it for 5 hours but used it to move from place to place and to reposition the kayak. I moved it at varying speeds and only used it at full speed maybe 20-30 minutes. I covered maybe 2 miles or so of water. When I got home I expected and hoped for 50% power use. I was pleasantly surprised it was still at 69%.Now this is important. I removed the 5 position switch on my motor and replaced it with a pulse width modulator. The 5 position switch is a resistor type, meaning it draws full power from the battery regardless the switch position. Slow speed draws the same power as full speed. The excess power at slow speeds is converted to heat, rather than being fed to the motor, so there is no power savings running at slow speeds vs. high speeds. The pulse width modulator only draws the power needed per the dialed-in speed so running at lower speeds saves power and thus battery life. At least, that's the way I understand it. So I really cannot speak of battery life using the stock 5 position resistor type switch. Regardless, if you need to cover a LOT of water distance then you may be better off with a larger amp hour battery. For my needs fishing, and just moving from spot to spot and positioning the boat, this works well for me so far. I'll update this review if necessary.

Gives me a full day fishing on my inflatable pontoon boat,

Bought this for my electric motor for a kayak. I have only used it once for a trial run so far, but worked good. Ran a 40lb electric motor and fish finder, I went up river against the wind for an hour, then motored back, used about 2.5 hours total and used very little power. Hoping to get at least 3-4hrs of fishing from the battery. But, I bought a 2nd battery and wired to be able to run in parallel together for long days and trips in a tidal river with strong current that I will fish with a 50lb saltwater electric motor. The battery seems to have good power for the weight at 23lbs. I put mine in a water proof plastic ammo boxes for easy transport and prevent corrosion, with plugs for the motor, fishfinger and a double USB with voltmeter. Works great, just drop it in, strap it in, plug it in and good to go!

My last Prius battery was also a lawn mower battery, but lead acid liquid....lasted over two years (died in the 100+ degree summer heat + from lack of use as we often go weeks without starting the car). Hopefully this AGM battery likes the Prius charging system a bit better. The original Prius battery is AGM, so I'm expecting this to jive better, but will update review regarding longevity if it becomes an issue.Came charged to the hilt. My trusty volt meter showed 16.8 volts. Yikes! Talk about making a first impression! I was a bit concerned about the high voltage, but my Prius shows no ill effects.I almost paid $2 extra for a competing battery on Amazon to get the carrying handles so was pleasantly surprised these came with them (makes installation so much easier). Also included are mounting bolts for the terminals. If you own a 2nd gen Prius (mine is a 2008), it's not a 5 minute drop-in job. I used a 10-inch piece of 2X4 to shim the battery hold-down (this battery is much shorter than original) and to act as a mounting substrate to secure any wires down using a big wood screw to act as a wire-mounting terminal. If you have one of those little metal hose clamps (99 cents for pack of 8 at my dollar store), wire mounting becomes even easier as you can use one to clamp the positive wire around a big wood screw and release the wire using the clamp in the future if needed.

Good purchase and value with this battery as advertised. I needed something fairly light with good charge to run my Minna Kota 301b thurst motor and this does the trick.

Great battery for a trolling motor. I use this with a Minn Kota on an Intex Seahawk 3. The first one I received had a damaged connection terminal, but the company was very easy to working with in order to get a replacement. I use this battery when I have to walk a little ways from the car to wherever I'm putting in the boat because of its relatively light weight. Have been out for 3-4 hours and haven't had any issue with it losing power or worried about it doing so.

Works well. Product was descibed perfectly and installed easily. Will definitely buy again if necessary.

went out on the lake for one hour or so ,suddenly no power, rowed thr boat against the wind with one emergency oar. looks like the fuses were loosebrought battery in to charge, after one day 11.7 volts, after second day 11.7 volts, gave up and purchased new battery from Walmart.After 4 days disconnected the mighty max from charger etc. next day gave it one last shot with charger. lo and behold after 8 hours 13.5 volts.Now I'm afraid to use it, What do I doFrank hamelin
