Why have these batteries not been recalled

These batteries manufactured by Ultratech have a very dangerous
habit of causing Fire and Burglar Alarm Systems to not function on AC power when they are depleted like normal batteries do.
Instead the overloads activate and the panels shut down. these batteries also bulge and in some cases have exploded.
The CPSC Consumer Products safety commission was notified of the problems with these batteries over a year ago and still no word the batteries in particular where manufactured in last 4 years and are as much as 2 pounds underweight compared to competitors.
I have stopped using these batteries along with UB Universal batteries for the same problem all together and have been replacing them with other manufacturers batteries.
