The battery debate in data center power: lithium-ion vs valve-regulated lead-acid (VRLA). Here what you need to know.
## Lithium-Ion Advantages
– **10-15 year lifespan** vs 5-7 years for VRLA
– **Lighter weight** – 60-70% lighter
– **Faster charging** – 2-3x quicker
– **Better performance** at high temperatures
– **Lower TCO** over lifetime
## VRLA Advantages
– **Lower upfront cost** – 30-40% cheaper initially
– **Mature technology** – well understood
– **No thermal runaway risk**
– **Easier disposal/recycling**
## Cost Comparison
| Factor | Lithium-Ion | VRLA |
|——–|————-|——|
| Upfront | $$$ | $$ |
| Lifespan | 10-15 years | 5-7 years |
| Replacement | Rare | Frequent |
| TCO (10 yr) | $$ | $$$ |
## Our Recommendation
For new installations: **Lithium-ion**
For budget upgrades: **VRLA**
