BATTERY BUZZ
Energy Density
•
The higher the energy density, the more storage power that can be put in a smaller package.
The higher the energy density, the more storage power that can be put in a smaller package.
Amp Hour
•
May also be called “Capacity” ( C ). Batteries are rated in “Amp Hours”‐ How much electrical current the
battery can put out for one hour. Charge and discharge rates are measured in multiples of the battery
capacity: a one amp hour battery discharged at two amps would be a 2C discharge.
Cycle Life (Rechargeable Batteries Only)
Cycle Life (Rechargeable Batteries Only)
•
A cycle is one full charge, and one complete discharge. Cycle Life is how many “cycles” the battery will last
until its energy is depleted and it is considered at “end of life”.
Self Discharge Rate
•
Self Discharge Rate is the speed a battery self discharges when not in use. During storage, the internal activity
of a b
f battery can cause it to h have l
lost capacity when you f
h first try to use it after taking it off the shelf. Some
f k ff h h lf
batteries (like lead acid) need to be on a constant “Trickle Charge” or occasional “Maintenance Charge”
(NiCd or Nickel Hydride) to ensure they won’t self discharge until they fail completely and cannot be
recovered.
Memory Effect
•
Use it for 10 minutes, recharge it; Use it for ten minutes, recharge it; Do this several more times and then try
Use it for 10 minutes recharge it; Use it for ten minutes recharge it; Do this several more times and then try
to use it for an hour‐ it runs for 10‐15 minutes and dies. This is typical of Nickel Cadmium and Nickel
Hydride batteries.
Temperature Performance
•
Batteries, like people, work best at 75o F. The efficiency of a battery decreases the higher or lower the
temperature. Some batteries cannot even be used at extreme temperatures . Some work very well.
