Which battery for a Yamaha 50D 2 stroke O/B

[miktek]

Hi there,
The battery my outboard came with (second hand) isn't really up to the job, it's actually a small motorbike battery.
Can anyone point me in the correct direction to get a particular battery capable of starting my outboard as well as running some very light powered toys, such as a fish finder/depth gauge.

The spec needed in the manual is as follows.

12V (obvs), 70Ah.
245 CCA (min)

thanks

That's a pretty small battery in reality so I'd look at small car batteries and find the cheapest you can which will probably be bigger than the minimum required
Don't worry about it saying Marine or leisure that's just an excuse to charge you more
As long as your not running accessories for long periods with the engine off you'll be fine

So a regular car battery out of say, Halfords should do the trick?

They do one at 70Ah, but it's CCA is 680, that's not going to cause any problems/damage is it?
Cost isn't really an issue as I'd rather get the best/correct one. In any case that one is £77.

More CCA is fine.
The Ah is generally not too important for engine starting etc, so I'd happily stick a something a bit smaller on there. £77 seems steep.

you can get one for about £60 from Halfords but it's a lesser quality and has a shorter guarantee, 3 years vs 4 or 5 I think.

Try your local motor factors. Mine sells batteries with 1 or 3 yr guarantee. Exactly the same battery they just put a sticker on it at the till! That tells me that they expect it to last 3yrs+ anyway. I'd probably not be able to find the receipt etc if Halfords need in 4 yrs time.

Thanks everyone!
