I think it's a cause for celebration. One of my ping batteries (36Volt 5ah)has reached the grand old age of 2 years. It's performing well beyond my expectations. It is used daily during the week and i reckon it's assisted either my wife's bike (or mine) well beyond 2000 miles probably nearer 3000. (Bike speedos aren't anywhere near as reliable so it's difficult to be exact). The mileage isn't particulary high i know, but the bikes are used daily, only the ice and snow prevented us from using them.
We try not to push them beyond 2C discharge, they have never been drained to LVC and i estimate it's been charged 200 times. It's true, i am nursing these little babies as much as i did when my daughter was young
.
With the same amount of care, I see no reason why it won't be serviceable for another 2 years or maybe even more.
At the moment the battery is paralleled on my bike with another 36V 5ah(18months old) through a high power schotty diode to give 10ah. The other bike has a 1 year old ping, which is performing well (of course).
I recommend Ping batteries
