Old stock, low capacity
Date code on batteries was Oct 2022, over a year old!Check with battery tester showed same capacity as new 12V 7AH battery. Internal resistance is 24 milli-ohms, whereas the expected range for a new battery of this size is 14-18 milli-ohms.Works good for now, but not expecting much in longevity. Avoid.

LOOKS LIKE THEY ARE OLD BATTERIES
Came without charge and after charging would not hold the charge even after only a few days. Also would only charge to 78%. Would never order from this company again!

Quality is very Bad
Very disappointed 2 out of the 8 batteries were defective. I did not contact vendor, I just added the name to my list of "Do Not Purchase From". I purchase a lot of batteries and I need Quality so that when there is a power failure the UPS's can do their job.

Old stock, out of spec
As mentioned by another reviewer already, they have been shipping old stock that has internal resistance out of spec (based on SigmasTek spec sheet and my SBS-6500 meter) . Also my most recent order in late 2023 had 2 defective batteries out of the box.I purchase batteries for about 90 UPSs. Since 2020, I have ordered hundreds of batteries from BatterySharks. Entire pallets at times.Their stock was fresh & reliable in the past, but unfortunately I can't say that now.
