I need to buy 2 new batteries for my 1999 outrage 21 ft w/ e-tec 250 hp motor.

What battery brand have you had good luck with?
Thanks

I've had good luck with batteries from NAPA Auto Parts.

For long service life and minimal discharge between charges AGM batteries provide excellent value. There are several reputable brands. Include your service type/size and do a search for good information. The only brand I am leery of is Optima. My current AGM brand is Deka.

The AGMs long service life makes up for it's higher cost.

I have Deka batteries and have been very pleased. 950 cca (cold cranking amps. My rule of thumb......heavier the better.......

---

Also Deka. x2

I've had excellent luck with Odyssey and Deka.

I’ve been using Deka on my other boat but was considering the Lithium Ion batteries for my 27 FC restoration. Curious is anyone has started using those? They are expensive as can be but supposed to get 2000-3000 cycles out of them and they are generally 70% lighter than AGM.

I've had good luck with the 2 Exide Edge dual purpose AGM batteries on my 1988 Outrage 18. Also less expensive than most other AGM batteries.

I believe I saw a thread discussing a boat owner who had installed Lilon batteries on THT. I've also seen discussions on Panbo. I would certainly first do a search on this site before trying elsewhere.

From the first hand reports I've read the Lilons performance exceeded expectations but the very high cost of the batteries and the required ancillary equipment to maintain the charging state properly was a disappointment. At least one individual reported that if they were to have to do it over again they would give it a pass.

If you are the type of person who doesn't mind being an early adopter and for whom budget is not critical it's probably worth a try. You can always go back to wet cell when the Lilons need replacement.

Certainly if weight is important to your application it could be very worth while. It was a real struggle for me to install Group 31 Dekas in our boat.

In the old days, a Sears DieHard was the only battery I would buy. Best service life, customer service, etc.

At one point I had Deka AGMs in my 3 boats, tractor and auto. Seemed like they all went at the same time. Although I was an avid fan of AGMs, one by one they got replaced with sealed lead acid. After a few years the AGMs wouldn't take a charge with my smart charger.

Today my battery of choice is a Duralast from AutoZone.

Having said that, this Summer I replaced the DieHard battery in my classic car. It was 23 years old. Yes, 23, not a typo. But of course, they don't make them like they used to.

I second gypsmjim's statement as I too had similar results with both the DieHard and Duralast batteries. My last cabin cruiser with 2 V-8's had Diehards in her and they were 16 years old and still cranked the engines and ran lights, sound and VHF when anchored.
