It was my own fault. I picked up the boat last Feb and sailed it to New
Orleans, never once considering if the batteries needed water. I put 4.5 GALS in 4 batteries last week! The other 2 (double size) are sealed. Tried today to start on bank 1, then on bank 2. Nothing out of either. All the batteries looked old anyway, so I reckon I am going to have to replace them all. How I'm going to get those doubles out, I have no idea... Any recommendations on make, longevity etc? -- Molesworth |

Do you know the size of the batteries? By the size you mention I could guess 8-D size. They are real heavy. They went in somehow, then they will come out, you might need a block and tackle to get them out. How many amp hours are the batteries? If and when you get them out, you might consider T-105 golf cart batteries. They are 6 volt and can be handles quite easy. They are a little taller than standard batteries. Still these batteries are the best bang for the buck. If your forgetful you might consider AGM type batteries. They charge faster and are a sealed type so you don't have to add water. Now this comes at a price, about 2.5 times the cost of T-105's This is just a quick reply to your question and I can be far more specific if you require Fair Winds Cap'n Dave |

AGM's seem to be the coming thing but there's no way I can afford 8 of 'em. And there's not a lot of load ampere-wise - florescent lights, mast lights, hot water (on occassion), laptop, depth meter, GPS, anchor winch ... that's about it, apart from the 4cyl 51HP Yanmar. Oh and I just bought a portable AC unit and an inverter (3000 amp). I already have a charger set up. Oh, and a refrigerator and the Lectra-San. Blimey. it adds up doesn't it? Sigh. Any guesses on my amperage requirement? Trouble with sailing is - you have to know everything else too. Today I was a sanitation engineer. Resited the L/S, drilled holes, replumbed it all, did the wiring anew and then found the V tube completely blocked. Like cement. Lawd knows how much of the pipe is blocked. I shall have to get that out tomorrow. -- Molesworth |

Any guesses on my amperage requirement? You won't be able to run an AC unit or hot water heater very long from batteries, regardless of size. You need a generator or shore power for that. The only reason to buy a 3000 watt inverter is to get the extra charging capacity that usually comes with it. To charge at a 150 amp rate you will need a battery bank of at least 600 to 800 amp hours. The cheapest way to do that is with 6 to 8 golf cart batteries in series-parallel. Do you have a high capacity alternator on your Yanmar of at least 100 to 150 amps? If so you can use it as a generator of sorts, powering your inverter with DC and getting 1000 to 1500 watts of AC out. That will power a small AC. |

"Nothing is funnier than a yachtie with a new 4000 watt inverter carrying his electric heater down the dock with a big grin on his face." 4,000 watts is certainly overkill for a sailboat but we get a lot of mileage out of the 2,000 watt inverter on our trawler. Both engines have 120 amp alternators which are bridged into the house bank through automatic battery combiners. When underway we have almost totally eliminated the need for using the generator unless we need multiple zones of air conditioning. Normally we alternate between the freezer and the refrigeration system, both of which have holding plates. As an additional plus, the inverter doubles as a 150 amp 3 stage charger. I'll probably never do this but it would certainly be possible to put a 200 amp alternator on each engine and get a 5,000 watt inverter. That would allow the freezer and fridges to run at the same time plus a zone or two of air conditioning. We have reduced generator run time by at least 50% using the inverter, and that is worth quite a lot in reduced fuel, maintenance, and increased quietitude. |

T-105, Golf cart batteries provide a big bang for the buck. L-16, Floor sweeper batteries would be best overall choice, if you have the vertical height to install them. Lew |

How I'm going to get those doubles out, I have no idea... You let slip a few details like the weights, and what kind of hole they are in you might get useful advise. Impossible to advise beyond sometimes a comealong and a 12 inch plank might come in handy. Trolling is OK, but you need better bait. Casady |
