## Battery Varta AUX1 35Ah 520A 12V

VARTA auxiliary batteries ensure that comfort features, safety devices and fuel saving functions work perfectly.
High-tech cars consume a lot of electricity. That is why these types of vehicles with a combustion engine usually include two batteries: a conventional 12-volt starter battery and an auxiliary battery. When changing a bad auxiliary battery, a proper replacement is very important. Likewise, an AGM auxiliary battery must always be replaced by another AGM auxiliary battery to avoid breakdowns or faulty vehicle operation.
