And also "plastic shell, which is rust-proof" You can't go wrong with rust-proof plastic 😬 Thanks!!

I undestand. Those are for the "standard posts" which are smooth and unthreaded. To avoid them and use cables with ring terminals I need a battery with threaded posts, or am I missing an alternative? Sorry Tracy,which connectors are you referring to? Some kind of adapter from standard to threaded posts? Thanks These? https://www.amazon.co.uk/QAQGEAR-Terminal-Compatible-243407F000-243407F001/dp/B09HGM7755/ref=asc_df_B09HGM7755/?tag=googshopuk-21&linkCode=df0&hvadid=641694953744&hvpos=&hvnetw=g&hvrand=17341636290188347663&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9046035&hvtargid=pla-1719653223826&psc=1&mcid=16818ffc281c3b4aae07173f68977dec

I'm trying to find a starter battery of 700CCA or above with nut terminals but cannot... I can only find with I think it's called "standard posts" which are smooth and unthreaded. Can anyone confirm that the BBS rules require that the batteries are threaded and adaptors are not allowed, or was I wrongly advised? Example: https://www.tayna.co.uk/car-batteries/yuasa/ybx5110/

I'm planning on having solar panels charging the starter and leisure batts separately, as in my previous boat. I think it works better that way. I will have a dedicated solar panel and controller charging this battery, so it should be ok. On my previous boat I had that and the cheapo starter battery supplied by Collingwood lasted nearly 8 years. Thanks for the advice on the type of battery. Access to this one is very easy and the leisure bank will be easy also.

Thanks Tony All three batteries will be removed, so no much problem in fitting a new one in this space, regardeless of the terminal position. As for charging it, I'll do that soon. These boats were on shore power all the time while on commission, but probably not after losing their jobs at sea.

Thanks! That's the info I needed the most. Thanks Tony and Black Rose. For now I need to know what battery to purchase, I'll deal with the switches, charging options and regulation requirements next.

Hello gentleman Indeed the battery bank must have been used for the lights and other instruments around the boat while in service, as there were no other batteries or battery holders anywhere on the boat. No labels on the cables neither. This was the setup, until we connected the Halfords "emergency" battery to get the engine started. Three Lucas 60ah batteries in parallel with some cables cut. A bit of a mess...

Hi I have recently bought a boat with a 40HP Lister-Petter fitted, and the starter batteries left are no longer charging (Yes, plural batteries. There were three in paralel, I suppose for extra reliability, being a lifeboat) Anyway, as they are no longer useable, I bought a cheapo from Halfords which started the engine with great difficulty, so I want to get a new one. Before I get another not-great one, is there a rule for matching the horse power of an engine (or is it the stater motor that matters?) to a suitable starter battery? I'm guessing larger engines will require more amps shoved up their bums in a short amount of time, but is there a rule as such, or just more is always better? And appologies for question n.2, which might be even sillier: is there also a reccomended upper limit for the amperage discharge at all? Should you absolutely not go over a certain amount? Thanks

They would be doing the maintenance very regularly while the boat was on the oil rig at the ready, but it could be that it never got to move from storage somehwere, or that it was decommissioned soon after, in which cases no one would have bothered.

Thanks a lot Peugeot. I need the drawings asap for a tank change, and maintenance will follow later. This is an ex lifeboat and the fuel filler needs to be outside like a regular canal boat, and a few other things like a breather pipe and fuel return hose, whatever that may be. I'll take the opportunity also to remove the ginomormous diesel tank and fit a 45L. I'll probably post a new post on that one tomorrow... As for the oil change and maintenance in these past 17 years... not sure it happened. Thanks Tony

Thanks a lot. I got a manual from https://www.winget.co.uk/wp-content/uploads/2020/12/LISTER-PETTER-LPW-LPWS-OPS-MANUAL.pdf The pictures are insanely bad I should be able to find better ones now with the full reference. Thanks a lot everyone. I think I'll be able to find my way around the engine somewhat...

Hi. I have recently bought a boat with the pictured Lister Petter 40HP. I understand it is not possible to determine the Lister Petter model from the serial number alone, so any tips on what this is would be very welcomed. Ideally I would like to identify the type so I could get a full manual and drawings, if any are available on the light or dark webs. Under Type it has "L4-186GB", but google had nothing to say about that. Thanks

Thanks Bee. I know about the hose now, and will have to decide on the best type of vent for my purposes. I don't know yet if it will be fitted horizontally or not.

🤐

Great. Thanks for that.
