Deep Cycle Batteries: Your Guide for Camping & Load Shedding in Alberton
In Alberton, the term "deep cycle battery" is no longer just for 4x4 enthusiasts. Thanks to load shedding, it's become essential for home backup power. But what is it, and why can't you just use a car battery?
"Sprinter" vs. "Marathon Runner"
This is the easiest way to understand the difference:
- A **Car Battery (SLI)** is a "sprinter." It's designed to give one massive burst of power to start your engine and is then immediately recharged by the alternator. If you drain it flat, you'll damage it.
- A **Deep Cycle Battery** is a "marathon runner." It's designed to provide a steady, lower amount of power for a long time and be deeply discharged (drained) and recharged over and over.
Why You MUST Use a Deep Cycle Battery for Backup
If you hook up a standard car battery to your inverter, it will be destroyed within a few load shedding cycles. It is not built for deep discharge. A deep cycle battery is the *only* correct product for:
- Home Inverter & UPS Systems
- Solar Power Storage
- Camping & 4x4 (running fridges, lights)
- Caravan & Marine Applications
AGM vs. Lithium: Which to Buy?
For deep cycle use, you have two main choices:
- AGM Deep Cycle: The reliable, sealed, maintenance-free workhorse. It's the best balance of cost and performance for most home inverters and camping setups.
- Lithium (LiFePO₄): The premium choice. It's more expensive upfront but is far lighter, charges faster, and offers thousands of cycles, giving it a much longer lifespan. It's the best long-term investment for serious solar systems.
