Best Trolling Motor Batteries?

One of my current type 31 batteries is no longer holding a charge. I think it is time to replace both of them. What is the best battery I can get for running two batteries in parallel for a 12 volt Terrova. I have both batteries installed under the console, and I have several inches of wiggle room. I had to put them there because there was not room for two type 31's and a cranking battery and a charger and two water pumps in my mechanical compartment at the back. I could fit two smaller tm batteries back there if they gave equal staying power, and if this is possible it is what I would like to do. I am selling this boat this fall and I think folks would prefer the tm batteries being where they are supposed to be. Boat is a PolarKraft 176ff Bass America ........ What would you go with?

Smaller won't be equal. I had to put 29s in the space under my deck. Pulled from 7 til after 2 Sunday and they were still going. 31s wouldn't fit.

I'm running 3 Trojan 1275 cart batteries on my Excel. Folks keep asking how long they will last. Honestly, I have no idea because I have never ran them down. They get plugged into the MinnKota 345 charger as soon as the boat is backed into the garage and stay plugged up till the boat leaves for the next trip. One huge thing to me is in the 7 months I have been running them, I have added water to them ONE TIME! Levels were still well above the plates. I keep a check on them and it is not an easy process getting all 3 of them out from under my center console. I couldn't be happier with them.

Better battery and much less $$$ than the Trojans or Optima's.

Keep in mind if space is a issue because most of the cart batterys are taller

The cart batteries also weigh 99lbs each. They are a BIG battery.

Lot of difference in run time between a 29 and a 31

U S Battery makes a smaller 31 series version of their big battery. They work really well also.http://uploads.tapatalk-cdn.com/2016...b09b3b3f11.png http://uploads.tapatalk-cdn.com/2016...f9fc78ee50.png

This is the BIG battery that I use. They actually make some bigger.

If you have the height, these are some Baaaad Cats.

When it comes to batteries just don't scrimp on the $ as I have done that in past and cost me more in long run [emoji23]

Thanks for posting that info BRM. Learned something today. Everyone of us who leave our chargers hooked up all the time need to read that little blurb under temp adjustment. Talking about equalizing each cell with automatic chargers. Hopefully someone can copy that section and post it. Good info.

Here you go

CHARGING INSTRUCTIONS:
Following is the charging recommendation and charging profile using 2 stage chargers for US Battery deep cycle products.
*Equalization and float charge modes are not considered to be one of the stages in a charging profile.

1. Bulk Charge Constant current @-1 0% of C/20 Ah in amps to 2.45+/-0.05 volts per cell
(e.g. 7.35 volts +/-0.15 volts per 6 volt battery)

2. Absorption Charge Constant voltage (2.45+/-0.05 vpc) to 3% of C/20 Ah in amps then hold for 2-3 hours and terminate charge
Charge termination can be by maximum time (2-4 hr) or dV/dt (4 mv/cell per hour)
• (Optional Float Charge) Constant voltage 2.17 vpc (6.51 volts per 6 volt battery) for unlimited time
• Equalization Charge Constant voltage (2.55+/-0.05 vpc) extended for 1-3 hours after normal charge cycle (repeat every 30 days)

Notes: Charge time from full discharge is 9-12 hours.
Absorption charge time is determined by the battery but will usually be +/- 3 hours at 2.45 volts per cell.
Float time is unlimited at 2.17 volts per cell.
Specific gravity at full charge is 1.270 minimum

Battery temperature adjustment: reduce the voltage by 0.028 Volts per cell for every 10*F above 80*F, increase by the same amount for temperatures below 80*•F.

Deep cycle batteries need to be equalized periodically. Equalizing is an extended, low current charge performed after the normal charge cycle.
This extra charge helps keep all cells in balance. Actively used batteries should be equalized once per month.
Manually timed chargers should have the charge time extended approximately 3 hours.
Automatically controlled chargers should be unplugged and reconnected after completing a charge.
