3. Gel Batteries: Use a gelled electrolyte; safe for various applications but sensitive to charging conditions.

What factors affect the lifespan of lead-acid batteries?

Several factors influence how long a lead-acid battery lasts:

1. Temperature: Extreme heat or cold can accelerate degradation.
2. Charging Practices: Overcharging or undercharging can reduce lifespan significantly.
3. Usage Patterns: Frequent deep discharges can shorten overall life.

When should I replace my lead-acid battery?

Consider replacing your battery if you notice:

1. Voltage Drops Below 12 volts: Indicates it may not hold a charge effectively.
2. Physical Damage or Swelling: Signs of internal failure or damage.
3. Frequent Charging Needs: If you find yourself needing to recharge often, it may be time for a replacement.
