I need to replace the battery (AA Patrol reported to renew as soon as possible). Recommended spec is 12V 112Ah 870cca.
I have a choice of (1) Yuasa HSB334 Silver 12V 100Ah 830A 5 years Guarantee and (2) Yuasa YBX3664 12V 112Ah 870A with 2 Years Guarantee.
I am tending towards (1) with 5 years Guarantee but (2) fits the spec fully with 2 years Guarantee.
Would you folks comment and give me some Pros & Cons for the choice.
Much appreciated.

Hancock MF31-1000 are good and just fit in the box loads of previous post on here everyone got there own favourites

With a P38 you get the biggest battery with the highest cca that will fit which is mf31-1000 as above 110-120ah 1000cca and they are not expensive.

Another one for the Hankook MF31-1000. https://www.batterymegastore.co.uk/product/hankook-heavy-duty-commercial-battery-mf31-1000/

Don't buy less than recommended spec. You'll just be buying another one at correct spec in a fortnight.

+1 for the 1000cca

I have a mf31-1000 too and it's great

Thank you all for advising on the battery to get. I am now seriously thinking of getting the Hancock MF31-1000.
Cheers

It'll turn the motor upside down, a good unit I must say.

Platinum on mine. Think code was 641X but it'll be on here somewhere.

Check setpoint on your alternator is above 13.8V if fitting a calcium battery and anything with 1000CCA is likely to be.

Got Hancook now, 643/644 Scania before but I toasted that. 750cca before that.
1000cca is a must for the diesel. Not so much on the V8 but you may as well bung the biggest you can in there itl keep the BECM happy. Price difference is negligible for the slightly smaller. May have to feed the red cable through a bit to stretch

In the process of fitting 2nd mf31-1000 in the boot for a night heater and fridge

Sounds interesting

Hankook MF31-1000 it will be. Some points to clarify:
(1) Grrrrrr says " Check setpoint on your alternator is above 13.8V if fitting a calcium battery and anything with 1000CCA". Yes it is Calcium battery.
(2) I read this "Calcium batteries are the most commonly fitted battery; they also go by the name of ‘wet lead acid’ batteries. The basic ingredients are no different to the old style, but these batteries are more durable and have more starting power. They have a good shelf life and are maintenance free. But they require regular use, so when drained they must be recharged using a charger to bring them back to optimal health. Modern vehicle charging systems will struggle to recharge these fully when they’re drained". Do I have any concerns for (1) and (2) ?
Thanks

Get the car running and check the voltage across the battery using a digital volt meter. If it reads 13.8V then I'd stick to a traditional lead acid battery. If you have 14.5V you're good to go.

Check setpoint on your alternator is above 13.8V if fitting a calcium battery and anything with 1000CCA is likely to be.

I read somewhere "The typical lead acid charging voltage is between 2.15 volts per cell (12.9 volts for a 6 cell battery) and 2.35 volts per cell (14.1 volts for a 6 cell battery). The ideal charging voltage for a calcium battery is 14.8V for the recombination process to properly occur"
What opinion do you have on this?
