First post, Greetings!! I have read several times that buying the same lot of batteries if possible may be best. Last Sept I began to order my system, it included 24 Rolls Surrettes S 1660 batteries. I discovered I could get same lot from NAWS by waiting about 10 weeks, so I placed the order. The batteries arrived Dec 7th, but they were not all the same lot as ordered, 2 batteries were older and not the same lot; one made in Jan 2015 (specific gravity 1.170) and the other battery made in April 2015. All the other 22 batteries had same lot number, same date of manufacture and a specific gravity of at least 1.230 These batteries were quite an investment, including shipping over $10,000.00 I have contacted my sales rep at NAWS and they are looking into it. I have contacted the shipping company in Phoenix and they are looking into it, but they wanted documentation such as photographs which I supplied. I am very disappointed after waiting and paying so much money for "same lot batteries" and not to receive them. But more importantly now, especially with these cold Northern Arizona temps, I do not want all these batteries to go without charging, should I go ahead and hook up all 24 (even the older one made last January) and start charging them up for the sake of the batteries? I have no idea how long resolving this problem may take (and have been advised such), or if hooking up the one older low specific gravity battery into the new bank could harm the other new same lot batteries?
