 I have a series 31 battery with 225 RC. What is the best wat to re-charge this battery. I have a charger that I can either use the 2 amps or 10 amps to re-charge. using one of the two settings how long should it take to re-charge. Or would I be better off having an in-board charger. Thanks for the help and good fishing to all.

 Well if you charge on 10 amps it should take a max of 8 hours, depending on if you are using automatic or manual charge. Manual is faster but automatic will give you a full charge everytime without risk of overcharge. On-board chargers are nice if you have somewhere to hook up to, otherwise they are as good as any other charger.

 Always charge a deep cycle marine battery at 10 amps.Some so called quick chargers will charge at 25 amps per battery. I dont like this. 10 amps per bank is the gold standard in charging. Two amps is considered a trickle or maintaining charge and will take forever to charge up a battery.Use it after you charge up your battery fully to maintain it (only if it is a fully automatic charger).Built in chargers are sweet.They are fully automatic and all you do is plug in at the end of the day and forget it.

 It will charge at a max of 10 amp, but they generally tail off the amperage toward the end of the charge to get it right up to full.

 The onboard 10 amp charger puts out a full 10 amps to bring a dead battery up to 75% capacity(over night) then it trickles at 2 amps until fully charged. I went to the onboard charger 3 years ago and it has saved my batteries. I was replacing a battery a year with the old box chargers

   I had from Gatream15 (  8/20/2004 5:58:00 PM
 a Sears 10 amp automatic external charger for years. My TM battery was getting weak. Load test was not good. 6 months ago, I got a Pro-Mariner Pro-Sport 12 2 bank and hooked it up. Same 2 year old TM battery now runs all day and 100amp load test shows it to be strong. The onboard chargers are so much better than the externals that it's just not worth not getting the onboard. And all of them are good.

 If you become interested in an onboard charger, there's none better than the Stealth. I suggest you take a look at what they are all about by visiting their site at They actually charge your trolling motor batteries by using the alternator on your outboard engine. Secondary they use 110 volts via electrical outlet.
