I'm pretty sure it is time to replace at least 1 of my 2 batteries. Battery #1 is an everstart maxx 29dc. Although my charger says it is full, it won't crank my outboard. I did let it get low on water and most likely cooked it. I also let #2 get low but it is working after a refresh and recharge. It is a regular 625 ca starting battery but I don't remember the brand. Here is my main question.... if I plan on leaving my anchor LED anchor light on all night, running fish finder, stereo and marine radio on during the day, should I use a deep cycle battery for that? I'm not sure weather to buy a deep cycle or a second cranking battery. Also would like feedback on seahawk brand batteries. A guy at the marina has one fairly new and fairly cheap.
