Batteries are the lifeblood of an RTLS. Unless you’re using passive tags (that have no battery), without batteries, the whole system shuts down.
The key types of batteries that you typically find in RTLS tags (and optionally, location sensors) are: Leclanché, alkaline, nickel-metal hydride (NiMH), lithium, silver oxide, zinc air, and nickel cadmium (NiCd). Some RTLS use primary (non-rechargeable) batteries, and others use secondary (rechargeable) batteries. This chapter describes ten important points to consider when using batteries for RTLS.
