Battery FAQs

1. What causes battery shell explosions?

A: Battery shell explosions require prolonged exposure to electrical sparks. The mechanism parallels coal gas explosions, though spark generation is imperceptible. Primary causes include:

1. External factors (90% occurrence):
   – Loose battery terminal connections
   – Vehicle wiring short circuits
   – Electrical leakage in automotive systems
   (These batteries typically maintain 12V-10V during discharge)
2. Internal defects (10% occurrence):
   – Failed internal welds
   – Manufacturing defects
   (Such units generally fail within 12V-0V range during discharge tests)

2. How to revive batteries that won’t accept charge?

A: For sulfation caused by chronic undercharging:

1. Agitate battery to homogenize electrolyte pre-charging
2. Apply 24V charge to individual cells, then reduce to 12V
3. Series-connect with charged battery for tandem 24V charging

3. Correcting reversed terminal charging damage

A: Recovery protocol:

1. Deplete residual charge using incandescent load
2. Parallel-connect with functional battery for 5 minutes (++/– alignment)
3. Initiate low-current (≤2A) regenerative charging
