When it comes to batteries and battery chargers, especially for load shedding or emergency purposes, the right choice depends on the devices you’re powering and how long you need them to last. Below is an overview of battery types and chargers that are often used in setups for dealing with power outages.
1. Types of Batteries
a. Lead-Acid Batteries (Deep Cycle Batteries)
- Use case: Popular in inverter systems and home backup setups due to their reliability and capacity.
- Features: These are heavy-duty and can handle deep discharges (down to 50-80% of their capacity) without being damaged.
- Options:
- Flooded Lead-Acid (FLA) batteries: Require maintenance (adding distilled water).
- Sealed Lead-Acid (SLA) batteries: Maintenance-free but have shorter lifespans.
- AGM (Absorbent Glass Mat): More durable, maintenance-free, and resistant to vibration.
- Lifespan: Usually 2-5 years depending on usage and depth of discharge.
b. Lithium-Ion Batteries
- Use case: More efficient, lighter, and with a longer lifespan compared to lead-acid batteries. Ideal for portable power solutions and high-demand uses.
- Features: They are more expensive but can be discharged deeper (up to 90% or more) without damage and recharge more quickly.
- Lifespan: 5-10 years, and they are typically more durable in extreme temperatures.
- Safety: Modern lithium-ion batteries have built-in safety features like overcharge protection and temperature.
