2.4 BATTERY CONSIDERATIONS
When considering a power solution for a design, the battery needs to be carefully
selected. Alkaline batteries are a commonly available option that delivers good
performance in a variety of applications. Energizer
®
Ultimate Lithium batteries are an
alternative power solution that provide superior-performance high drains and allows
designers to utilize the full power range of the MCP1663 without sacrificing size or
runtime.
Energizer Ultimate Lithium batteries utilize a primary cell chemistry that contain higher
energy than alkaline batteries, and have much better high drain performance. Ultimate
Lithium batteries produce a high, flat voltage profile that enables them to provide a high
energy capacity even at high drains. Additionally, Ultimate Lithium batteries have a very
low internal resistance, allowing them to maintain a high voltage at very high loads.
