Product Review Of The Interstate SRM-29—Are These SRM Batteries Even AGM?
First off, let us waste no quarry and head to some of the “perks” and “goods” that the SRM-29 of Interstate can bring forth to your marine and boat activities:

– It possesses one of the higher CCA ranking/ratings with 670 amps to ‘cold crank’ your boat batteries.
– It possesses one of the higher RC ratings with over 210 (minutes!) to help you continue running your appliances/applications while in the water.
– And yes, you get the assurance (as with other top brands out there), that this product uses an AGM model to keep the internal vibration resistance low and thus, keep the temperature in control just as well.
And, while this is a most personal and subjective type of measurement, the budget is reasonable enough if your expertise borders more on its immediate uses and it will most likely serve you well because of this regard.
