31M-825CCA Battery

It is a good hevy battery

Replace this type of battery on my RV works wonderful

You had better have some help putting this in your boat. It's definitely no lithum. This thing is heavy! I have not had it in my Cobalt 222 very long, but compared to my other battery, it spins the motor and starts the 8.1L big block almost effortlessly it appears. A welcome change. It charges quickly. I am not sure of the longevity, but I was quite impressed with the packaging, the instructions and the build quality so far. They say most batteries are produced by a handful of manufacturers and then branded. I am not certain of that and so I cannot speak to it. I will say so far so good on this one and for the price point, this might be an exceptional find. Again, its one heavy unit so might need some help getting this where you want it in your boat.

Awesome battery

Received the batteries earlier than expected and in perfect shape, worked well for my application, RV with solar panels.

I ordered two of "Weize BCI Group 34M Dual Purpose AGM Battery, 120RC 650CCA 12V 55AH Starter & Deep Cycle Sealed Marine & RV Battery"s for my 8-cylinder 253 HP Mercury boat engine starter. They arrived in two days! they were totally enclosed in a thick foam box, no worries!! The quality of this battery is exceptional and shipping was fast. I liked this battery so much and for the price. And they start my boat engine immediately within one second right after you turn on my boat starting key, and you can feel these batteries are so powerful that they push the starter easily and quickly! It says 2 year warranty and hopefully they will last longer for a few years. Let's see and fingers crossed.

Works great has lasted several days without charging running as power battery for rv, lights and 3 nights with cpap, bought to replace a size 27, just a little smaller with this 24 series very heavy, alot heavier than the old one,i was surprised, hopefully last a long time ,if not I will update my review.

The battery was well packaged and arrived on time, fully charged. I installed it in my boat, and only time will tell how long it will last. So far, I am very pleased as it starts my boat right up[25 hp Yamaha outboard].
