AGM(Absorbent Glass Mat) 배터리 : 10년
SLA(Sealed Lead Acid) 배터리 : 5년
AGM 배터리(Absorbent Glass Mat)는 유리섬유 매트에 전해액을 흡수시킨 고성능 납축전지입니다. 일반 배터리보다 충·방전 효율이 뛰어나고 수명이 길어, 스탑앤고(ISG) 기능이나 전력 소모가 많은 현대 차량에 주로 사용됩니다
AGM (Absorbent Glass Mat) is actually a type of SLA (Sealed Lead Acid) battery. You aren't choosing between two different things, but rather determining if the specific sub-type (AGM) fits your needs better than other SLA options like standard flooded or Gel batteries.
Choose AGM If:You need high power delivery: AGM handles high electrical loads and cold-cranking amps much better than Gel.You require deep cycling: AGM batteries can discharge up to 50–80% of their capacity and recharge reliably without degrading as quickly as standard SLA types.
You want no maintenance: They are completely spill-proof and require no water refilling.
Choose Standard SLA (Gel or Flooded) If:
Budget is the priority: Standard SLA batteries are significantly cheaper than AGM batteries.
You are using it for standby power: For low-drain, infrequent uses like basic UPS backups or security systems, standard SLA is highly cost-effective.
You need extreme vibration resistance: Gel SLA batteries handle vibration and extreme heat better than AGM.
Summary Verdict: Choose AGM for performance, heavy-duty starting power, or deep-cycle uses like RVs and motorcycles.
Choose standard SLA if you just need a budget-friendly battery for a backup alarm system or a basic toy.
