Review: Energizer Li AA battery - High energy content. Excellent Lithium batteries. Price is worth paying.
Review: Battery leaked but also charged successfully with high currents which is not trickle! - These batteries tends to maintain peak performance until most of its capacity and then it will die quickly! Initial voltage were 1.81 volts/ cell. And if you give some rest to these batteries then it will again crank up the voltage to around 1.7 Volts. If you want to charge them then you have to trickle charge them at 20 mA outside!! (Only for experimental results, beware) If you want to buy then use it in medium drain devices for best battery life or if you want performance then you can use it in high drain devices like motors or Cameras 👍 Battery can leak if current limit is high or they heat abruptly! So charge current should as low as that of an led which is 20 Ma. For more details see the internet, and they would take UPTO 6 days to recover outside!! Only experimental trickle charging but with a higher voltage than 1.4 volts! The voltage should be as high as 1.85V for lithium metal or Nizn batteries and trickle charge @10mA only!!! due to the electrolytes being used and to lessen the dendritic growth and get extra capacity atleast some extra!!! It works but risk involved so use it wisely and carefully!!! Thanks 🙏😊💚
