We only guarantee these packs to capacity test at their individually tested amp hour rating. A packs ability (or lack thereof) to hold a full charge is a reasonable indicator of it's remaining lifespan. Because of this lifespan consideration the packs are priced on a curve instead of a set amount per Ah capacity.
Item sent could have grey or black top versions as pictured, just depends on current stock.
