Rapidly charging a lithium battery is one of the major factors in reducing its lifespan. That is part of why you see a longer lifecycle for this battery.
It could also be the onboard electronics are different than they are for the normal lifecycle battery. It's unlikely the cells inside are different. It is also likely the long lifecycle battery is priced at a high enough premium over the standard one to cover the replacement cost, should the battery not last the three years the warranty covers.
Yes, I expect that ExpressCharge will reduce the lifespan, but nothing prevents not to use ExpressCharge.
Both 4 cell batteries are available with the Precision for the same price.
Can we infer that the Long Cycle Life battery is nothing else than a standard battery with some firmware that totally disables the ExpressCharge option, so that the warranty is extended to three years ?
