Well, I accidentally bought a boat deep cycle starting motor battery for my boat's trolling motor instead of a trolling battery for it 3 years ago. I have two battery chargers, and when I use either one to charge my trolling motor battery, it takes over 18 hours to have a full charge. What is wrong? Is the battery not good or something, or is it because I am using a deep cycle boat motor starter battery for my trolling motor?

It's calcified. A deep cycle battery is what you want. Try buying a 'fancy' digital charger that specifically says it can recondition old batteries. The high freq. pulses of high voltage can break up the crust that accumulates on the lead plates of the battery. (full disclosure, I have a Vector battery charger and it has brought a marine deep cycle, lawn tractor, and motorcycle battery back from the dead. It has more than paid for itself.)

Hi! Do not worry. You have bought the correct type of battery. Ordinary car batteries are designed to discharge a high amperage for a short time and then, when the engine has started the battery is being recharged by the cars' alternator. A deep cycling battery is designed to discharge at a fairly low rate for a considerable length of time between charges. This is known as deep cycling. The average trolling motor will consume approximately 7 amps . The usual size for a deep cycling battery is 75 ampere hours. Therefor if your charger is of the high output type it will typically recharge your battery at the rate of 4 amps per hour. A quick calculation tells you that this will take between 18 and twenty hours to fully recharge. If this does not fully answer your question I will be happy to give any further advice. You can contact me via this site or by email at paul.lee28@btopenworld.com. I hope this information is of help to you. Many hours of happy trolling on your boat. Regards,Paul.

it takes that long to charge because it is a deep cycle battery...the special deep cycle battery charger really helps...also it is best to go with low amps...longer time with those.
