Tazuma 49 AGM

The Tazuma 49 AGM delivers 850 CCA and 92 Ah with 160 minutes of reserve in the Group 49 (H8/L5/LN5) footprint — the largest battery in the Tazuma Automotive lineup. A baseline AGM upgrade over flooded with better vibration resistance, more consistent electrical output, and start-stop cycling durability. 24-month full replacement warranty from West Coast Batteries.

Fits Mercedes-Benz E-Class and S-Class (W213/W222+), BMW 7-Series (G11/G70), Audi A6, A7, and A8, Porsche Cayenne and Panamera, and Land Rover Range Rover and Discovery. These vehicles run adaptive suspension, multi-zone climate, large infotainment, and advanced driver assist — all drawing from the battery. Most came with AGM from the factory and require AGM as a replacement. These charging systems are calibrated for AGM chemistry — a flooded battery will cause charging faults and premature failure.

BMW, Mercedes, Audi, and Porsche vehicles in this group all require battery registration after install.
