    Battery

    What’s a good cranking battery for the new 4s 250hp that won’t break the bank?

    Needs to be an AGM, with 975 CCA (or better). Do NOT use the "MCA" ratings or CCA Ratings... there is a lot of questionable "print" information on this in various manuals.

    There are a number of brands that carry a large 31 series AGM with 1050+ CCA ratings. Batteries Plus, Northstar, etc.

    Once your engine and battery are together- be sure to provide the Required info (serial number) when posting. Thanks!

    Watch their Coupon Codes on their website- If you order online (and pickup in store) you can often get at least a 10% discount.

    Also make sure you take a core with you... $21 when I last checked.

    Can anyone tell me the reason Mercury requires an AGM battery on the new 4 stroke?

    I am not disputing it, I just would like to understand why.

    Thanks

    While there are likely a number of reasons, the two most important would be:

    -Throttle and Shift System demands/requirements ***

    -ICBM (Idle Charge Battery Management) Strategies require consistent battery type.

    *** Even the "mechanical" models are Digital Throttle and Shift engines- AGM batteries have been required with DTS equipped engines for many years.

    Thanks for the information....

    So my dealer put a flooded cranking battery in my boat until the factory sends him an AGM that was supposed to be in the boat when he got it.

    I guess I will not run it until the AGM is installed.....

    very frustrating.....

    A lot of dealers don't know. I bought a 250 Verado equipped boat a few years back and had to explain it to the dealer, he sold mostly skeeter/Yamaha and didn't know Merc very well.

    Look at the Duracell 31 mag, it's a great battery for the money. Made by East Peen, who also makes Deka.

    I 2nd the AGM style, my previous dealer put wet cell batteries on my twin verados, and its caused havoc for just over a year.....until (I) figured out the problem....and, after they had replaced half the electronics on my boat!
