    Back when D9 cats dozers had 398's (393?) in them they had a small petrol engine to start them

    exactly powerabout, and other caterpillar engines of the same era were pony start, including marine engines

    Pistnbroke,
    :) Asking who Jesus is could REALLY get this thread off track.

    So....to keep this Flog and Pony :p show on the road, it sounds like an electronic battery sulfator is a valid concept. (?)

    I had started looking at the possibility of purchasing one for my poor, abused trolling motor battery, but never posed the question here. I quick look on the web and these possibilities jumped out.

    Or something with a lower price...

    Any comments on the these products?

    there's also 12v powered versions so no ac required
    They just draw a small amount from your battery and desulphate it

    I would also like to know the answer to this. I have imported a yacht with a 110V US system to Australia (240V). It has a 1800W Heart inverter/Charger that charges at up to 65 amps.

    I have the choice of getting a 240V/110V step down transformer ($100) to run the heart as a 65 amp charger. Or the second option is to get a new style 25A charger ($250) which has all the new fancy automatic charge cycles with desulphation etc. So I wonder if it is worth it to spend more on a charger that will have less power than the heart, but has the fancy desulphation. My batteries are trojan T125s which are only 3 years old, but they were left to run down for around a month and have never been 100% since.

    are you sure the 60/50 hz difference will not give you a problem ??

    As for the de sulphator I just made one up from a kit ..about $20 but how do you know if its done anything !!!!!...unless of course its a dud battery you are trying to revive

    sounds like your batteries could do with raising to 15.5v for a couple of hours...

    I am pretty sure the 50/60hz thing is not an issue as these transformers are used widely on imported boats from the US. But I have to admit I am not 100% certain and some further input on this would be good.

    Every month or so since I left the USA 9 months ago I have done a 15.5V charge for a few hours. I think it has helped. The prob is that I get very low voltage out of the bank. Its always hovering around the low 12 high 11 mark even with low loads. But it still seems to have capacity, but I have not tried to push it to see exactly how much it has left.

    Is your desulphator a jaycar kit? How big of a battery is it rated to?

    may depend on how much electronics it has in it ..ie it may be all solid state and no actual transformer for the charging ...maybe ask the makers if it can be used on 110v 50 hz which is what you would get in europe

    I am not sure the makers are around anymore. At least I could not find them on the net. I have some documentation which says the input can be 90-130V AC. The frequency is not mentioned. But with such a high tolerance in voltage would think the frequency would also not be critical. My other issue is how much power I need the transformer to be rated to. There is no mention of the input power required. But 14V X 65A = 910W. Then add inefficiencies and I am thinking the 1000W tranny I had found cheap may be at the limit. However in practice the unit would not usually be operating at full power.

    Seems like I am dragging this thread OT again :p

    If it will take such a range of voltage maybe its all electronic?? I would have a look inside ..you may find a transformer in there thats two 120v windings in parallel which could be re configured for 240v.....good luck ...

    Well it did come in a 240V version. I will take a look.
