Figure 15. ECN Battery Compartment Location
The ECN uses intelligent battery charging techniques to maximize the life of the
battery. That is, the ECN occasionally discharges and recharges the battery to
maintain battery capacity and prolong its life. A typical discharge/charge cycle
can take up to 16 hours. During this time, the ECN could be vulnerable to power
loss during the discharge cycle, so you should use dual battery packs. Each pack
can be independently charged on alternating cycles so that a fully charged
battery pack is always available. Each battery pack has an operating life of
approximately 10 years.
Figure 16 shows a typical battery pack.
Figure 16. Typical Battery Pack
Each battery pack is comprised of six AA size (IEC HR6 / ANSI 1.2H2) batteries
to provide 1800 mAh or 2200 mAh at 7.2 V with 12 cm (5 inch) connection leads.
Table 3 on page 29 lists specifications for the battery pack.
