Customer Reviews
I purchased a 24M7 lead acid Marine Master battery, in July 2000. I just load tested it and it finally would not hold a charge. After almost 6 full years of marine life! It had an 800 CCAmp rating. I cant seem to find it (800 CCA) anymore. So I purchased a new Marine Master AGM 750 CCAmp battery from battery mart online. In just a few days, it arrived. I fully charged it last note. Did a load test that fully passed, ant installed it in my boat. I would highly reccomend Deka for marine batteries. It cost about 100 bucks extra, but I depend on only 1 battery to bring me back when I am way off shore. I wouldn't have it any other way. I am not getting paid for this review. I thought everyone out there, who needs reliability, should know how Deka Batteries served me.
Ordering and shipping were easy and quick. Battery went in without any issues.
COMPARED WITH OTHERS, THIS IS BEST VALUE FOR THE SPECIFICATIONS. aLSO,I DIDN'T HAVE TO BE BOTHERED WITH CORE DEPOSITS AND CORE RETURNS.
i us it for my 5th wheel power and chang it with solar power and works very well...
So far I am very please with this purchase. Battery mart had the best prices around. Time will tell if the battery holds up but when not in use it is on a trickle charger so all should be good. I will update if it fails prematurely. Good STRONG battery
I've used the DEKA brand for many years. They perform very well Especially the AGM batteries. Love the zero maintenance.
I have them installed as primary power to an emergency sump pump system and to power an automated security gate. Both applications are security related.
I use this for my solar power.
