Have purchased more than 60 of these batteries over several orders and timeframes. While all performed very well at first, some from varying time frame orders failed within 6 months requiring rebuilds of packs, while others, much older, continued to perform well. Feels like a crapshoot whether you will get good strong long-lasting batteries or not. Pretty expensive crapshoot.
Pros:Perform very well - at first.
Cons:Inconsistent quality from order to order.
