Batteries are the last thing on people’s minds when they are in a hospital. However, without batteries, there would be many barriers. There are many pieces of equipment that run on batteries, and this includes blood analyzers, heart monitors and infusion pumps, as well as defibrillators – so that’s a lot of Yuasa SWL2500EFR batteries!

Reliable power sources are a must for hospitals. If a power outage were to occur, then they’d need backup equipment. The backup equipment used often runs on batteries, hence another reason why they are so important.

The US market for medical devices is huge, and it generates over $100 billion in revenue, and that is one of the largest markets in the world. Equipment manufacturers do experience issues when it comes to devices that operate on batteries. Battery chemistry is one of those issues and so are discharge profiles.

Battery Chemistry

The main AC supply is what powers many devices used in hospitals. This means batteries receive only a shallow discharge before they are recharged. One basic flaw is lead acid that is sealed up and lead acid that is regulated by a valve. The issue is internal resistance.

When internal resistance increases, then a drop in voltage can occur due the sudden need of power. This is a bad thing and can cause a bit of a problem. When batteries are matched to devices, manufacturers tend to make the mistake of not choosing batteries that have an appropriate amount of international resistance.

Fast Charging

High rate charging sessions can result in peak charging rates for batteries to decline and this is due to chemical changes and physical changes that the battery cells face. It’s a good idea to use the lowest current when charging the battery. Then it should be charged only when … Continue reading >>>
