What Is the Most Reliable Battery Type for a Generator?
When designing our battery-powered backup generators, EverSafe first considers:
- What customers rely on backup power for
- How they use it under real-world conditions
For backup power systems serving hospitals, labs, and other medical facilities, there are two key requirements:
- The system must perform perfectly even after long periods of non-use.
- It must reliably provide strong, safe power instantly when needed—for example, for operating rooms or critical lab equipment.
Because of these requirements, EverSafe uses AGM lead-acid batteries, since they are well-established, very reliable, and stable. These batteries are especially suitable for medical settings such as clinics and surgery centers. They also offer top safety and reliability for backing up vaccines and other critical medical items.
What Are the Strengths and Weaknesses of Sealed Lead-Acid Batteries?
Many medical devices—patient monitors, surgery tables, infusion pumps, heart monitors, blood analyzers—use sealed lead-acid battery systems. Although other battery types exist (such as lithium-ion, common in phones and laptops), EverSafe selects sealed lead-acid batteries because they tend to be safer and more dependable for medical usage. Lithium-ion batteries can sometimes fail catastrophically and are generally less rugged than sealed lead-acid models.
Sealed lead-acid batteries offer many benefits:
- They retain performance even after long idle periods.
- They are leak-proof and can be oriented in various positions because they use special mats or separators to contain the electrolyte.
- They pose fewer shipping concerns (not classified as dangerous in many cases), so delivery is easier.
- They are less expensive and simpler to manufacture, which helps control costs.
Drawbacks include things like lower depth-of-use per cycle and somewhat shorter lifespan compared to more advanced battery technologies. For instance, they might last around 500-1,000 cycles, and charging might take longer. However, in many medical backup scenarios these limitations are less problematic, since usage is intermittent and systems are designed for occasional load rather than continuous cycling.
Why Are SLA-AGM Batteries Ideal for Backup Power?
Because of their many benefits, sealed lead-acid AGM batteries are an excellent fit when safety, stability, maturity, reliability, leak-proof design, and ease of shipping are high priorities. Additionally, they hold stored energy for long periods and can deliver enough power consistently. These qualities make them a strong choice for ensuring that the equipment in your facility is backed up safely and with minimal compromises.
