Review on Long-Lasting EBL 9V Lithium Rechargeable Batteries With USB 5400MWh Capacity (Pack Of 2) by Bill Gomez

I charged the batteries when I received them. I let them sit and rest for 24 hours and plugged the charger in it took 23 minutes to recharge them back up. One battery will not hold a charge for more than about 30 hours. They say they''re good for smoke alarms WHAT? WARNING do not trust them in smoke alarms only lazted less than a month in 3 brand new smoke/CO2 alarms these batteries as far as I''m concerned are dangerous in CO2/smoke alarms don''t risk your family''s life. Toys, Radios ?
