At SJ Dynamics, we supply and install a full range of UPS and inverter batteries designed to keep your systems running during power interruptions. Batteries are the backbone of any backup power solution, whether paired with UPS systems, solar installations, or generators. Choosing the right battery technology ensures reliable performance, longer service life, and better value.
Lead Acid Batteries
The most common option for UPS systems, sealed lead acid (SLA or VRLA) batteries are maintenance‑free and widely available. Semi‑sealed batteries are cheaper but offer fewer cycles and shorter lifespans. With load shedding now a regular occurrence, many users are moving away from semi‑sealed options toward more durable technologies.
Gel Batteries
Gel batteries are filled with a gel electrolyte, making them more robust and resistant to extreme temperatures, corrosion, shock, and vibration. They are ideal for demanding environments where durability is critical.
Absorbent Glass Mat (AGM) Batteries
AGM technology provides faster recharge times and higher cycle life compared to standard SLA batteries. They are well‑suited for applications requiring frequent charge‑discharge cycles and consistent performance.
Lithium Batteries
Lithium batteries have become increasingly popular as prices have dropped. Although more expensive upfront, they deliver exceptional value with:
- Service life of 10+ years
- 3,000+ charge‑discharge cycles
- Faster recharge times
- Remote monitoring capabilities
- Scalability — additional batteries can be added later
Lithium technology is now the preferred choice for long‑term, high‑performance energy storage, especially when integrated with solar systems and UPS solutions.
