[C320-list] 4D Batteries

[Dave Hupe]

I replaced the old original charger (ran hot constantly and scared me) on my 1994 boat with this 40-amp digital ProMariner ProNautic one that had very good reviews for $313 in 2018 (now $528) at Amazon:https://www.amazon.com/ProMariner-63140-ProNauticP-12-Volts-Battery/dp/B004NPOT4G#customerReviews
I also installed this remote charger monitor for $75 in 2018 (now $87) from Amazon:https://www.amazon.com/ProMariner-63100-ProNautic-Display-Battery/dp/B009PIR0EW/ref=pd_bxgy_200_2/140-1791473-6856910?_encoding=UTF8&pd_rd_i=B009PIR0EW&pd_rd_r=6YATJSBP7NBVTKN7NQHK&pd_rd_w=pNhMI&pd_rd_wg=yDBvF&psc=1&refRID=6YATJSBP7NBVTKN7NQHK
I am very happy with and strongly recommend the charger and remote.  I subsequently recommended these to several other C320 owners who installed the same and have reported great results.
Upon the recommendation/experience of another local friend with a 320, I purchased this 4D comparable battery for $165 (now $257) from NAPA auto parts https://www.napaonline.com/en/p/NBP7266 .  This battery has been great ….. and much less expensive than others discussed on this topic.  It has been in service 7 seasons now with no signs of a problem. 

I do not do much more than day sails and charge at my slip otherwise, so this experience may not help for someone planning extensive trips/overnight.

Trying to find something that can allow us to use the refrigerator for more than a day or two, or is that never going to be possible no matter the brand. Don’t want to install solar, not worth it for us we only do long trips maybe once a year. We have hull 74 1994 and still has original charger/inverter, does that have something to do with it? Anyway, anxious to hear some feedback.
