Pengetahuan tentang Battery/ Batere /Accu

Klasifikasi Battery

Primary Battery

Yaitu battery yang setelah satu kali dipakai tidak dapat dipakai lagi atau tidak dapat di “recharge”

Secondary Battery

Yaitu battery yang setelah dipakai dapat dipakai lagi atau dapat di “recharge”

Jenis-jenis Battery:

1. Primary battery

         -Carbon-mangan diokside (tidak dapat direcharge)

2. Secondary Battery

        - Nickel cadmium (polusi & karsinogenik, harga bahan baku sedang)

        - Nickel metalhydride (bahan baku mahal)

        - Lithium metalhydride (bahan baku sangat mahal, densitas energi rendah)

        - Zinc carbon (harga bahan baku sedang, teknologi masih mahal, masih tahap awal percobaan)

        - Lead Acid (bahan baku murah, teknologi matang, densitas energi memadai)

Lead Acid Battery (Berdasarkan karakteristik penggunaan)

1. SLI

      - Starting, Lighting, Ignition.

2. Motive Power

      - Untuk alat yang digerakan listrik, seperti mobil listrik, forklift, dll.

3. Industrial

      - Untuk pengunaan di industri, seperti: PLN back up power, telekomunikasi.

4. Deep Cycle

      - Untuk alat-alat dengan karakteristik khusus, seperti : lokomotif kereta api, photo voltaic system
