Lead Acid-Batteries vs. Other Battery Technologies
Many of the batteries that are used in renewable energy systems were originally designed for other purposes. The most prominent example of this is the lead acid battery which has dominated the industry for a long time.
Deep cycle lead-acid batteries have proven to be one of the best (and most affordable) battery types for alternative energy system battery banks for these reasons:
- They’re able to withstand frequent discharging,
- They’re cheaper than other kinds of batteries,
- They have more rugged durability,
- They deliver more consistent performance than other batteries.
The fact that they are widely produced also means that they are relatively easy to replace if a battery in your battery bank needs replacing.
It should be noted though, that as of late, lithium ion batteries for residential alternative energy systems, like Tesla’s Powerwall, have been gaining ground – but the initial investment into lithium ion batteries is still much more than the initial investment into lead-acid batteries.
The Powerwall may eventually change this but at the moment deep cycle lead-acid batteries are the cheapest and most practical solution for a home battery bank.
