Frequently asked questions

Can Yellow Top be used as a normal starter battery?

Yes, perfectly. CCA is enough to crank any car. Pick it when you also want deep-cycle capability (audio, winch, fridge, motorhome).

Does it need coding?

If your car needs AGM and has a BMS, yes — the management system must know it is AGM. Yellow Top is BMS-valid AGM.

How long does it last?

5-8 years in normal use. 3-5 years in extreme use (competition audio, off-road).

Why pricier than a normal AGM?

SpiralCell is a different process plus 99.99% pure lead. The premium pays back in extra service years and in applications where flat AGM would fail.

How long does shipping take?

Standard delivery 1 to 5 working days to your country. We process orders within 24h.

OPTIMA Yellow Top — dual-purpose AGM SpiralCell

The difference vs classic AGM is the SpiralCell geometry: instead of flat plates, Yellow Top uses 99.99% pure lead spiral-wound plates. Result: 350+ cycles at 80% DoD (3-4x flat AGM), tolerates extreme vibration (off-road, marine), works in any orientation.

Models and applications

Model	Ah (C20)	CCA	Typical application
YT S 4.2	55	765	Cars with HiFi competition audio, modified
YT S 5.5	75	975	4x4 with winch, extreme audio, motorhome
D34/78 YellowTop	55	750	American pick-up (Jeep, Dodge), modified JDM
D31A YellowTop	75	900	Big pick-up, 4x4 expedition, RV
D75/25 YellowTop	48	620	Classic American restomod

Yellow Top vs Red Top vs Blue Top

Yellow Top (dual-purpose): cranking + deep cycle. Modified cars with audio, winch, 12V fridge. Red Top (starter): cranking only. Cars without heavy auxiliary loads. Blue Top (marine): same as Yellow Top but with marine terminal + white case for boats.

Why Optima over a conventional AGM

Vibration: SpiralCell tolerates vibration that would crack flat plates (off-road, racing, rough marine).
Deep cycle: 350-400 cycles at 80% DoD vs 100-150 cycles on conventional flat AGM.
99.99% pure lead: 1-2% per month self-discharge (vs 5-15% for lead-antimony or standard calcium). Survives months unused without sulphation.
Any angle: mountable on its side or upside-down (terminal not facing down). Ideal for atypical compartments.
