The best battery replacement for a Cerb nowadays is...

The Exide 069RE appears to be NLA

The Varta D39 is a very reasonable £66, only £7 more than I paid five years ago

Well I'm slightly bemused, and happy to acknowledge the hint of "I told you so" in some of the posts.

The S4 009 doesn't fit my 96 4.2 Cerbera, fouling on the rentention plate nut.

I will take another look about, at the moment I have a P62 05 Banner on it, terminals are the wrong side, but that doesn't bother me. Plenty of same size batteries out there with decent CCA and AH

the plate is movable. undo the 2 bolts -they're captive underneath so no need to fight with a spanner on the underside.

Oh interesting! Well that at least makes sense now, thank you!

I’ve just fitted an Optima Red Top on mine and can’t believe how well it turns over now. It’s like it’s on ‘speed’ the difference is really remarkable. The old battery started it just fine but I’d noticed it struggling a bit on the second or third start if it missed the on the first crank, it also kept going in to battery recovery mode on my optimise charger. Worth the extra cost for the higher Cold Cranking Amps in my opinion.

[HarryW]

The only issue I have is can you easily access the terminals with a battery conditioner with the red top.
I admit it has great cold cranking capacity but the 078 type batteries already mentioned below are half the price and are a perfect fit, and in my case provides more than adequate cc for my lump, which has a much greater compression than most Cerberas, spins up just fine.

[CerbWill]

Yup, positive terminal is right in the cut out for it. I connect the negative clip of my accumate to the a/c compressor.

[Adambul]

My battery conditioner came with a water proof double connector that I’ve permanently wired to both battery terminals, it tucks under the battery cover panel. Easy to connect/ disconnect each time you use the car. Works a treat but I take the point over the cost of the Red Top.
Another advantage though is it spins the engine so fast that I can get oil pressure up before it starts which is handy if the engine has been left for a few weeks without being run.
I have a separate starter button on my Cerbera that’s direct wired to the starter and by-passes the immobiliser as occasional the immobiliser plays up.

Another option for the adventurous, at a price that even I would consider

[RUSSELLM]

I jinxed mine. Said it was 7 years old in March, and it died in May

Replaced with another Bosch at £89 delivered.

Liteblox LB20XX. Well, you said 'best' - not 'within a price range'... :P

Very brave @20Ah, battery kill switch and ability to leave the bonnet unlocked a must.

I would argue Deadweight's Touge Max was better for half the money.. 950CCA and 120Ah.

With advanced internal protection circuitry? And - crucial for Griffs and Chims where the battery is buried deep in the passenger footwell - remote on/off, diagnostic and antitheft functionality via Bluetooth? And last but not least - does it weigh only 2.0 kg?

Yes. No remote on and off, but a mechanical cut off is fine, or with that capacity it will sit for a long while. It weighs 5kg, but then it's capacity is much bigger (2.5-3.4x) and much more powerful and more suited to a Cerb. I am sure that 3kg wont be noticed, nor do you need a custom battery holder.

Some nice gimmicks/features on the Liteblox though, and got to love a bit of CF. It is the "cooler" battery for sure.

That is a tiny capacity, a Cerb will flatten it in days if left sat, or won't do well with a light left on by mistake when you park up etc.

[Gazzab]

Had to buy a battery in a hurry. It has sat for months and so is ‘terminal’. Bought the same again ie:
Type 078 Varta Silver Dynamic Car Battery 12V 63Ah (Short Code: D39) (Varta DI

Total: £74.50
Seller: tayna-batteries(259,456)

Ordered yesterday via eBay. Arrived this am.

Painful experience has taught me that there is pretty much a linear relationship between the quality/reliability of LiFePo4 cells and the price of the end product.
The actual disposable capacity of lithium, AGM, and conventional 'wet' lead-acid batteries in relation to their Ah rating is completely different. As a rule of thumb, with AGM batteries I'd go for half the Ah rating of the standard battery it replaces, and halve the rating again for a lithium battery.

It's correct that you can't get away with leaving the lights on for very long with the smaller capacity batteries, but only a fool would run an expensive lithium battery without an automatic cut off that shuts the power off when it drops below ~12.6V (i.e. more than enough to start the car), anyway. Once it drains to below 10V, it's 100% certain rendered a very expensive paperweight.

Having said that, the battery is the easiest place to look if you want to lose some serious weight from your car.
