Advantages of Primary Batteries
Primary
batteries, also known as non-rechargeable batteries,
tend to get overshadowed by the media attention secondary or rechargeable
batteries receive. Heavy focus on one product over another may convince folks
that primary batteries are old technology on the way out. Not so.
Primaries play an important role, especially when charging is impractical or
impossible, such as in military combat, rescue missions and forest-fire
services. Regulated under IEC 60086, primary
batteries also service pacemakers in heart patients, tire pressure gauges
in vehicles, smart meters, intelligent drill bits in mining, animal-tracking,
remote light beacons, as well as wristwatches, remote controls, electric keys
and children’s toys.
Most implantable pacemaker batteries are lithium-based, draw only 10–20
microamperes (µA) and last 5–10 years. Many hearing aid batteries are also
primary with a capacity from 70–600mAh, good for 5–14 days before a replacement
is needed. The rechargeable version offers less capacity per size and lasts for
about 20 hours. Cost-saving is the major advantage.
High specific energy, long storage times and instant readiness give primary
batteries a unique advantage over other power sources. They can be carried to
remote locations and used instantly, even after long storage; they are also
readily available and environmentally friendly when disposed.
The Fello Tech have LiSOCL2 batteries,LiMnO2 batteries and Button cell batteries. They are widely
used in Small devices, security
equipment, gas Meter, Punching machine, blood gluose tester, Camera ,telephone,
electric rice cooker, calculator
Moving into higher capacities and better
loading leads to lithium-metal batteries. These have very strict air shipping
guidelines and are subject to Dangerous Good Regulations involving Class 9
hazardous material。Figure 1 compares the specific energy of lead acid, NiMH
and Li-ion as secondary, as well as alkaline and lithium-metal as primary
batteries.
