    As for the product, everything OK. However as to order the order the seller placed the CEP (ZIP CODE) wrong. I almost missed the package. I had to go in the back to collect the merchandise.

    I had to buy this replacement because two of the same supplier had failed prematurely. The failures occurred while in storage over winter in my home; the cells expanded and distorted the case, they also degraded in energy capacity. I don't know the cause for the failures, they were not abused or misused. The replacement has an added label that warns of environmental exposure over 45C but no other guidelines for storage. These packs contain cells that are specified to allow a slightly higher state of voltage charge and I wonder if storage at full voltage (4.25V) causes their premature demise. I found the following statement on Wikipedia: All Li-ion cells expand at high levels of state of charge (SOC) or over-charge, due to slight vaporization of the electrolyte. In other words, the design of the pack causes an over stress of the chemistry while at full charge. Also the warranty period is unclear on this pack. I could not obtain any warranty compensation for the premature failures.
