Yeah, sears has a Platinum Charger for $99 but save your money and get this one: VEC1087C car battery charger
If the Sears battery is the same as the Odesey it must be AGM? How did you figure that out, the Sears website give very little info that I could find?
I am active on some battery discussion groups where it was noted that they were the same but that Sears contract with Odyssey would soon run out unless renewed at a higher price since lead went up from their contracted price and thus the "deal" doesn't have long to live! Yes...both SearsPlatinum and Odyssey are AGM but a very UNIQUE AGM...
I only need one maybe two hauls between charges.
I thought AGM's could handle faster discharge rates or is that only faster charge rate?
AGM's CAN handle FASTER discharge rates...typically around 40-50% of rated capacity...Odysseys can handle OVER 100% of rated capacity...thus you can get away with ONE odyssey battery since I figured you'd hate me if you had to haul TWO AGMS or a couple of 4D wet cells!
From Sears site:
The PM-1 Platinum Marine Battery from DieHard features 205 minutes of reserve capacity and 1150 cold cranking amps. Provides power for RVs, trolling motors, marine accessories and starting needs. The combination stud/post terminal design allows for multiple connections. Its corrosion-resistant high quality tin-coated brass terminals provide reliable starting power in all weather conditions. Its rugged, military-grade construction features robust casing for increased compression and offers superior vibration resistance.
Does this mean 205 minutes to dead at 25 amps. YES
100 minutes to half charge at 25 amps
40 minutes at 62 amps
40 / 7 minutes per haul is about 6 hauls
NO... Wrong rating. You first figure the current...in amps which is 62. Then you figure the time which is 7/60ths...or 7 minutes draw. That gives you amp HOURS used 7.23 to be exact. So...with a 115ah capacity at the 20 hour rate the Odyssey can be discharged to an 80% depth or 92ah's before requiring a recharge. (Other wet or AGM's should be 50-60% depth). 92 amp hours divided by 7.23 ah's per haul gives you about 12 hauls.
