Hello shack7a,
The normal life of a CMOS battery is 3 to 5 years. To be honest i've had them last up to 6 years. It is diffcult to say why your battery has died after just two years, it maybe just an inferior battery. I suppsoe you could ask the same question about a watch
battery. Why does one battery last 12 months and another 18 to 24 months?
CMOS batteries are not that expensive and are easily changed, so long as you know where to find it on your motherboard. With some motherboards you cannot miss the battery whereas others it maybe hidden by wiring or somthing similar.
I wouldn't worry about it only lasting 2 years, just change it and, hopefully, this next one will last longer.
