Data center environments have changed faster than many battery replacement strategies. Key trends include:

1. Higher Temperatures

To reduce cooling costs, many facilities have raised setpoints. Even modest increases accelerate battery aging.

2. Denser Racks & AI-Driven Loads

AI and high-density compute introduce rapid load transitions and higher peak demand.

3. More Frequent Cycling

Short 5–15-minute autonomy windows mean UPS batteries discharge and recharge more frequently.

4. Higher Float Current Over Time

As batteries age in hotter, heavier environments, internal resistance increases, which leads to higher float current and greater heat output.

Traditional VRLA continues to serve many applications well. But these shifting conditions mean some sites benefit from extra resilience, efficiency, and recovery speed.

DataSafe® HX Specifications

Valve Regulated Lead Acid (VRLA)

A widely trusted technology offering dependable performance for many UPS applications. VRLA remains the right choice for numerous data centers operating within conventional temperature and load conditions.

• Proven chemistry.
• Strong performance in stable temperature environments.
• Widely deployed across data centers.
• Supported by EnerSys recycling programs.
  
  

Thin Plate Pure Lead (TPPL) Technology

A refinement of VRLA chemistry using pure, thinner lead plates to increase surface area and lower internal resistance.

What TPPL adds:

• Higher power and improved efficiency at the 15-minute rate (to 1.67Vpc @ 25°C / 77°F).
• Uses pure, thin lead plates.
• Offers lower internal resistance and faster recharge.
• Better performance in hotter rooms and high-rate discharge.
• Lower float current (which can support lower cooling demand).

Think of TPPL technology as an advancement and as an option for sites where conditions have moved beyond the typical VRLA envelope.
