It's a 9V alkaline battery. Non-rechargeable primary battery.



Anticipated battery life is as follows (cut from specifications in first post page 1)

Typical current consumption and battery life (based on fresh Alkaline battery 500mA/hr 23C)

basic functions backlight off 11mA 45hrs
basic functions backlight on 16mA 31hrs
beacon mode (backlight on) 25mA 20hrs
LED on (backlight on) 34mA 15 hrs

for most people the battery life is essentially the shelf life, at 4-5 years.

If you use the unit professionally, or if you use the LED functions extensively, you may need to replace the battery more often.

9V Lithium batteries can be used and will yield 2-3 times the battery life, but are expensive.
Standard 9V "Heavy Duty" carbon zinc batteries may also be used, but the battery life will be shorter.
