OPTIMA YELLOW TOP Batteries
The OPTIMA YELLOW TOP is a dual-purpose battery: it starts the engine and, in addition, withstands repeated deep discharges to power high demands. It is recognized by its yellow cover.
SpiralCell technology
Share the pure lead spiral cell SpiralCell, but with an internal configuration prepared for cycling: it supports hundreds of deep discharge cycles without losing capacity, it recharges very quickly and maintains a high cranking current. Sealed, maintenance-free and mountable in almost any position.
Applications
- Electrically intensive vehicles
- Competition audio, winches and inverters
- 4x4, motorhomes and prepared vehicles
- Applications combining starting and consumption with the engine stopped

How to choose
Choose YELLOW TOP if your vehicle uses a lot of electricity besides starting: high power audio systems, winch, refrigerator, inverter. If you only need starting, RED TOP is more economical and sufficient.
Equivalences
The YELLOW TOP is the dual-purpose range of OPTIMA (yellow cap): starting and deep cycle. It is positioned between the RED TOP (starting only, red cap) and the BLUE TOP (marine, blue cap).
Frequently asked questions
What does it mean that the YELLOW TOP is for dual purpose?
Does both things: delivers the engine cranking current and, in addition, supports repeated deep discharges to power high demands, something a starting battery cannot withstand.
How many deep discharge cycles can it withstand?
Hundreds of deep discharge cycles thanks to the spiral cell, far above a conventional starter battery, which degrades after only a few deep discharges.
Is the YELLOW TOP suitable for a high-power audio system?
Yes, it is one of its typical applications: it withstands the strong discharges of a competition amplifier without degrading and recharges quickly between uses.
