Battery floating voltage

Thanks mate, see this link for Century batteries, "SLI/Flooded Absorption Charge 14.2V to 14.5V and Float Charge of 13.2V to 13.5V" this info is at the bottom table....

"CY103-1029 BatteryTalk Newsletter (Issue02).indd"...drop that into Google to see full pdf.

 

Hey Pistnbroke,

A while back Eric Sponberg did a series of articles for us here on design and NA type themes, they were seriously excellent as they were written for the likes of myself with the intent to help us understand some quite important principles...may I ask you to do the same on say:
Selecting batteries
Charging batteries
Alternators and repairs
Starters and repairs

...I am sure that your experience in the field is far more important to boat users than technical articles that mean bugger all in real life situations...ta, John

 

13.2-13.5v ..if they say so but they assume its a starting battery being used regularly so its gets up to 14.4v after each start not left for 18 months.

You could say frosty used the wrong sort of battery but as there is bugger all difference between leisure and starting ( traction is a different thing) then I think his only error was not a high enough float and not using them . Remembering that a modern hi tech/programable charger would have given them a regular rise to 14.4v.

The ultimate boat charger/monitor is the Smartgauge www.smartgauge.co.uk

 

Easy peazy then --just unplug the charger and leave deck lights on all night, then plug it back in again in the morning.

 

So why the big laugh the floating voltage is supposed to be 13.3 to 13.5

I'snt 13.4 right in the middle?

 

yes for a starting battery you are using regularly.....

Why turn the charger off ...??? just turn the deck lights on for a few hours every week ...the charger should respond to the drop in voltage on the batteies and go into charge mode

 

No--it wont go into charge mode --the batts are charged so it just takes up the slack. It certainly isnt going to take them to de sulphating mode because of a 4 amp draw

I thought you knew stuff.

 

if its in standby and you put a 4 A load on it should move up to the baulk charge mode which raises the voltage ....no point having an charger which does not respond to the loads and state of the batteries....put it up to 13.8 anyway.

But you aint called Frosty for nothing

 

Well it dont--even if I flush the bog and watch the guages at the helm I can see 25 30 amps on the flush then a return to 13,5-13.4. Ist that what they are supposed to do.

If I took the batteries off it would cope with it.

Are you saying My Master volt has a volt fault

 

My last word are .....

Your batteries are like your Dick ...it needs a regular discharge and charge to stay fully functioning . If you leave it in standby too long then when the call comes it wont function ....got it .....

 

Yes,-- well your preferred subject was predictable.


Ille wait till some one that knows about batteries comes along.

You stick to what you know best.

 

They have been along earlier in the post but have given up

 

It would have been much better had you not posted at all,--(teacher at technical college bollocks). I dont believe you were any thing but a gas station tyre fitter.

Well done piston for destroying the thread , now I will never get to know any more. Now ille be as dumb as you are.

Ille buy some new batteries and continue in my ignorance.

 

No body has destroyed anything Frosty you have been told what the problem is and how to put it right with a new set or keep going with the old ( if the bog flushes) ..

There are some people who only learn by being forced to sit in a lecture theatre by there employers ....eventually most get the message..

A very few however are so blind that they never see.....

 

No --I have been told by an Aussie who thought it the funniest thing they had heard of for weeks then back pedaled into agreeing.

It would have really been better had you not posted,--thanks.

Can I ask for no further advise.
