Varta on hea.
Aga optima kohta selline info
REDTOP Starting Battery: Use this for normal engine starting where an alternator immediately monitors the state of charge and provides energy to the battery whenever it is needed.
YELLOWTOP Deep-Cycle Battery: Use this when electrical loads are higher than average, or when the discharge cycle is more than typical engine starting, such as vehicles without alternators. This also includes vehicles with significant electrical loads that may exceed the average alternator output (for example, aftermarket audio systems, GPS, chargers, winches, snowplows, inverters, drag cars). This can also include vehicles that have a lot of electronics from the factory, such as a minivan with power sliding doors and a DVD player, especially if the DVD player is used when the engine isn’t running.
BLUETOP Marine Battery: The BLUETOP starting battery (dark gray case) is to be used when a dedicated starting battery is required; it should never be used for cycling duty. The dual-purpose BLUETOP (light gray case) can be used for both starting and deep cycling; it is a true deep-cycle battery with extremely high cranking power.
Seega kollane sobiks ka matkakasse. Ja selleks neid ka kasutatakse.
Hind muidugi on mõrvarlik küll. Samas halba nende kohta kah pole kuulnud
