BassmanfromNC Posted February 20, 2010 Posted February 20, 2010 I'm a rookie with this stuff. Got a couple questions. I called a store about a deep cycle battery they stated the reserve amps 150 annd CCA like 550. I thought deep cycle batteries didn't have CCA but only the dual ones do?? He stated they do have CCA. Does this sound right? As far as charging, I've been told to leave the battery hooked up to charger with low amp setting. I have a vector smart charger that does the 3 stage charging. The box says it cuts off when fully charged to prevent overcharging. My question is if it shuts off charging will it restart when needed to keep the full charge if left attached to battery while in storage? or does it just shut off altogether? Thanks Quote
Super User Way2slow Posted February 20, 2010 Super User Posted February 20, 2010 A true deep cycle will usually only have the amp hour rating using the 20 hour method. Read this, it will help you understand that http://www.windpowerunlimited.com/batteries/Amp_Hours.htm. Sometimes they will use the reserve capacity in minutes. The reserve capacity is how many minutes the battery will last with a 25 amp load. Usually when they have a CCA or MCA rating on them, they are usually considered for dual purpose use. Either way, the battery you mentioned is going to be a rather small battery if you're only going to be running one for your TM. As for your charger, it's a cheap charger that's only intended to charge the battery. Being a three stage it may probably has the float mode but do not leave it connected after it turns off until you verify the float voltage. Never leave just any charger connected to a battery on a low amp setting. What your not understanding is some chargers have a build in float mode, that it switches to once the battery is fully charged This is a maintenance mode thats keeps the battery at the ideal storage voltage, it is NOT a trickle charge. Even on the cheaper Smart chargers like your's that have the float mode, you need to check their float voltage after 24 hours to ensure it's the proper voltage. Not too many of the those $50 chargers maintain the proper voltage. Good chargers that are best for your battery are somewhat expensive, usually over $100 and closer to $150 - $200+. Quote
