Is it worth it to invest in the higher priced 8D batteries?

My batteries are .... old. Really old. I have to check the dates on them but I am sure they are ready for replacement, just in case. I'm not having any problems starting yet but I don't want a dead battery in the middle of the desert.

I invested in Crown's for my house bank. I spent 1300-1400 on them. Looking at the price of Trojan 8D's .... ugh. I'm tempted to a buy a set of THESE Duracell batteries. They're 1400CCA and $180 a piece. Thoughts?

Why not just a couple $80 group 31 batteries?
Mine are holding up GREAT.

I second the AGM 31s. Two of these make about one 8D, and they're easier to move around.

2 31's is often better than one 8D. And much easier to move.

Yeah, I've got to be in a very good mood to pick up an 8D. Lots of lycopene.

The only advantage of 8Ds is their much greater Reserve Capacity for repeated cranking, but if you can temporarily connect your house batteries to the start batteries then you don't need all that RC. A pair of Group 31s are half the price, half the weight, and will start any engine just fine unless you're in Alaska in the winter.

Go with the cheap 8d or 31s like others have mentioned. Don't swing for the high end Trojans. You already spent a mint on your awesome Crown house batteries.. call it good.

I get my batteries from a local mom and pop battery shop and they serve me just as well as any chain-store batteries (usually better), not to mention being quite competitive on price.

I'd switch from 8D to a pair of group 31 batteries if it were me.

I would have done 31 if I didn't get a great deal when I bought the bus to have 2 8d for 375 installed. I've had the bus since April and I keep it on a float charger... Even if I forget to put the charger on for a couple of weeks like I did just recently it has plenty of power to crank right over

Jumper cables and AAA? Mine is parked in an RV lot and I jumped with the car when needed. 4 yrs old but got tired of waiting for 15~30 minutes to get it to fire.

Just bought 2 of these a month back. No problems yet unless you count the strain of the back when taking the cores back. I am NOT on a trickle charger. Fires right up. Got mine from Batteries & Bulbs. 10% discount with online ordering.

Crap!!! Looks like they are $150 now plus 10% off. I paid $180; time for a phone call.
