Hi,
Does anybody knows what battery capacity is needed to crank up a volvo penta 2003?
Thanks for help

Its not really battery capacity that matters its cranking amps. CCA or MCA. However there is no information in the manuals on that.
As you will have read your owners manual says a maximum of 70Ah, although no one seems to know why Volvo Penta specify a maximum capacity.
I suggest any car type battery with a capacity in the region of 60 or 70 Ah would be suitable.
If space is an issue look at Red Flash, or similar, batteries with the same CCA rating as a typical 60 or 70 Ah automotive battery.
If it was not so cold I'd go down to the garage and read the CCA rating of my 70Ah car battery for you!

A typical 70Ah start battery will have a CCA around 630, in Europe the EN norm is normally used so the specs would list it as A(EN) 630
Optima red top in comparison is 50Ah with CCA of 850

Have a 2003 and got a 100Ah 850Amp CCA and that seems to work well - was a 'dead ringer' for the previous DELCO that died after more than 8 years of abuse.

Found a service manual for the 2003 in Swedish http://nf.broach.se/motorer/volvo-penta/Volvo Penta 2001 Verkstadshandbok svenska.pdf
It says 70Ah starter battery

The CCA requirement for starter motors for Yanmar 1, 2 and 3 cylinder engines is 200A. It seems likely that Volvo ones are not too dissimilar. So far as capacity is concerned I know of several Red Flash 1100 batteries being used to start 3 and 4 cylinder Volvos and Yanmars. Capacity of this model is 38 Ah. I have one myself with a Yanmar 3GM30F, starts perfectly every time. Until recently my starter battery was only 13Ah, worked OK when fully charged but ran out of puff if the engine was reluctant to start.

...of course the other consideration is what will fit snugly in the existing battery box, assuming there is one.

Or between the gearbox and the side of the shaft tunnel, which is why I use one. Frees up a space for a third 110Ah domestic battery.

If you speak English rather than Swedish the owners manual, along with all the other VP owners manuals, can be downloaded from VP's website at
http://www.volvopenta.com/volvopent...lication_search/pages/publication_search.aspx
The workshop manual and a selsction of other manuals can be found in English at http://www.bluemoment.com/downloads.html

any battery that starts a small car would do the job

within reason !
Some very small batteries, eg 28Ah 190CCA, as fitted to some cars with small petrol engines might be pushing things a little.

Beta Marine variously specify 400CCA (and 45Ah) or 500CCA (and 70Ah) for their 2 and 3 cylinder engines (see http://betamarine.co.uk/wp-content/uploads/downloads/operators_manuals/1590-1025-HEKC-SOM-0714.pdf).
(DMS Technologies specify your Red Flash 1100 at 775A Maximum Discharge Current (20C, 30secs) http://www.dmstech.co.uk/red-flash/red-flash-high-rate/.)

Vic my 27Ah Red Flash 750 battery is now installed after many suggestions here earlier, and is starting my 2GM20 no problems at all within 5 secs even when cold. This has now allowed me to incorporate the old 90Ah into the domestic bank making it 310Ah, great result.
For your info Engine Rated 16HP - 1 Kw Starter Motor Battery 27Ah CCA 410

Very neat. But it does have an MDC of 530A rather than one of about 190A, which is I guess what Vic was expressing particular caution about!
VicS

Absolutely.
The 2GM20 is also only a 635cc 2 cylinder engine. Significantly smaller than the 1280cc 3 cylinder VP 2003.
(To bring the data for the Redflash 750 in line with figures quoted for other batteries its CCA @-18C, according to DMS Technologies, is 410A although you will find some very misleading values quoted by battery suppliers)

The CCA rating will normally be based on testing, underwhich the battery voltage falls to about 7V (7V is used, as generally this is the lowest voltage that most 12V vehicle systems will continue to work down to). This means that a battery with a CCA of 190A will kick these 190A out at 7V (1330W). Your starter on your VP 2003 is around 1.4kW (lets say 1.7kW to allow for ~20% over tolerance), then you need a battery that will have a CCA of no less than 243A.
THat is of course assuming you'll need to start your engine when it's at -18°C, which unless the engine is fitted in an icebreaker, is unlikely! Performance at normal boaty temperatures is likely to be much better, but using the CCA as a benchmark in marine applications means you naturally overspec the battery by a reasonable amount.
This means that the RF750 or RF1000 would be more than adequate for this application. I'd personally go for the RF750 due to it having female terminals - much less hassle/chance of them breaking if overtorqued.

It seemed odd that no Volvo CCA spec has been found, and I was interested to read in Vyv's post that the Yanmar 1, 2 and 3 cyl. CCA specs were 200A, that being so much lower than the Beta specs. I wished to install a dedicated start battery (for an older 3 cyl. Beta), and wanted plain lead acid mainly for charging compatibility reasons. Having space, I ended up IIRC with about 70Ah, not because I wanted the capacity but in order to get a high enough CCA.
Thanks for that - I couldn’t find the CCAs on a very quick look on the Red Flash site. And yes, I’ve seen the CCA of the Red Flash 1100 given as 775A, but that's its MDC (I see the CCA is 500A http://www.dmstech.co.uk/downloads/DMS_data_redflash_highrate_web.pdf).

I did add the spec for the battery to my post 13 as an edit ! but you can find all the RF battery specs here

P.S sorry I just noticed you have put the link on already :sleeping:

I recently replaced the start battery on our 2030 with this -
http://www.halfords.com/motoring/bu...alfords-calcium-battery-hcb096-4-yr-guarantee
The previous battery (fitted from new) had a CCA of 500 with a 56ah capacity. I had no reason to buy a larger capacity other than the fact that the above Halfords battery measured pretty much the same size as the old battery even though it has a larger capacity so it made sense to go with this.

Sorry - I took that as the engine spec rather than the battery spec :apologetic: (and I don't think it was there when I first wrote). No probs about your adding the link to RF CCAs - yes, I had put it in, but it wasn't immediately obvious to me when I looked on their site and might not be to others either.
