vexilareye Posted June 29, 2011 Share Posted June 29, 2011 I have searched and couldn't find a post on this. I have a 2001 Mercery 125 and am in the market for a new starting battery. This battery will also run my LCX 19, 522, and livewell, bilge, etc. Not all of these will be on at the same time. Just wondering what battery you guys would recommend? What CCA's or RC does a guy want for this use? Any help would be appreciated. Thank you. Quote Link to comment Share on other sites More sharing options...
BobT Posted June 29, 2011 Share Posted June 29, 2011 The CCA rating of the battery is needed to determine if the battery can deliver the power necessary to start your outboard. Could check with your outboard owner's manual or local outboard dealer for details. The owner's manual for my new 2011 90hp E-tec recommends 650-750 CCA.The ideal choice for what you intend to do is a dual-purpose battery that has the CCA rating you need. The reserve capacity will be adequate to handle your other electronics without issue. Just don't use it for operating your electric trolling motor unless you like to pull start your outboard.
