Duracell 8D's?

[Mike36c]

So I discovered one bad battery and I've decided to swap out all four and start fresh. After reading threads here and searching online I found a new ( to me) company, Batteries and bulbs that has a 1400CCA heavy duty duracells locally for $162.00 with exchange. Theses are advertised to weigh 130lbs each so it seems they aren't skimping on lead. Has anyone tried these or this company?

Bought two Duracell group 31 AGM batteries for my bow thruster a while back. I'm happy with those if it helps any.

I have 6 Duracell GC2's in my house bank. Not sure my experience is applicable to 8D's, but I've had good performance with no complaints.

Mike, I don't know how you use your boat, but if you cruise away from your battery source, be sure your battery warranty will be easy to honor where ever you are. After being nailed twice because of lack of local service/dealers and 'house brands' I switched to popular brands, NAPA for the 8-D's and Workaholics for GC-2.

Rolls hhg 8d is 175 pounds 15+ year life expectancy

Sounds like a pretty good price. Sams Club sells duracell and I think the 8d's were $190ish. I'm going to switch away from 8d at some point...too heavy to get in and out and even though I'm young compared to the wise men here, my back can't handle the 8d.

Your engines can start with a group 31. Cummins did a good job of keeping the required amperage low. My Detroit's won't start on single 31.

Mike, I replaced all four of my 8D's with the exact batteries you are talking about from my local Batteries Plus + Bulbs for my 44TC. My Detroit 8v71's have no problem starting with them. I have not had any problems at all other than they are back breakers to install. The price is unbeatable and I have no regrets for buying them.

Thanks everyone, I've got to make a phone call to our local battery shop that delivers and installs to see how much the price difference (my back) is I only weigh 45lbs more than each battery and will probably tap out after the first one. Is it feasible to replace the 8D's with two smaller batteries that will fit in the boxes and have equal starting amps?

I would like to see a battery manufacturer offer a three or four piece 8D equivalent with the required cabling to take the significant danger of personal injury out of handling this battery. Some here have done it on their own, how about some pics of the successful?

I would not replace the 8d with one group 31. I'd use at least two batteries. The internet says three group 24 (and maybe 34) fit in 8d space.

My RV has same engine and two batteries in parallel to start it. It also has 2 8d gels for the house, but they are on a slide out tray and much easier to get to.

3 group 24 will fit in the 8d space but according to my battery guy will not equal an 8d overall. Krush for your boat this will be a great fix for ease of service since they are a lot easier to handle.


Also FWIW.

I know I only get a 1 year warranty on the heavy duty 8d batteries I sell. The smaller ones sometimes have longer warranty periods

I have replaced a single 8D with two Group 31s just because of the weight/size issues. Changing an 8D is such a pain. You just have to make sure your battery box will hold the additional width (an 8D is about 11" wide while a Group 31 is 13" long and idealy you put them in sideways so it is easier to cable them together. )

 

[Mike36c]

Thanks again everyone. I spent some time at the battery shop going over some options including North Star AGM's and multiple smaller batteries. As mentioned above three group 24's will fit in my 8d boxes, initial price is higher but much easier to deal with down the road. For now I decided to replace with heavy duty 8d's and although more $$ per battery than the duracells for $150 this company will deliver four 8d batteries, install, and take away the cores. I'm under a time restraint to make an upcoming trip so I'll go with a different set up next time around.

I have had good luck with Lifeline batteries. I have 6 of their 31's but they are pricey.

I gave up changing batteries a while ago. I'm having 4 new 8Ds installed this week. It will cost me about $200 more than if I did it myself but for that $200 I don't have to go get the new ones or return the cores, don't have to bug a friend to help get them in. I'm sure I'll save more than $200 in lost work by not killing my back!
