"Cracking the case of my 140 reveals a compact sealed lead acid battery. I was pleased that it is intact and not leaking.
The battery is placed for easy replacement. It is placed above the circuit boards. If it leaks serious damage could occur. I'll be thinking about replacing it next year, just like the car battery.

The original internal UPS battery is a Panasonic LC-R121R3PU (12 V, 1.3 Ah), the cell found in the units when first opened. It carries the equipment maker's caution "Danger of explosion if battery is incorrectly replaced", and one is etched with the date code 980310. Computer Magic's 2001 quick-reference sheets name a PowerSonic PS-1212 (12 V, 1.2 Ah, 3.82 x 1.65 x 2.00 in), most likely the replacement they supplied.
