Revive your dead battery! These superb charges use the ‘Pulse’ method of charging which means that despite its current rating, the charger first checks the voltage of the battery by charging with a very low current. If the battery voltage is too low it will continue to charge with a low current until such time that the battery voltage reaches a nominal level when full charging current can be used to charge the battery. This means that this charger can even charge ‘dead’ batteries whose voltage has dipped below cut-off voltage! This alone sets this charger apart from the competition – we have run numerous tests on batteries with very low voltage where an equivalent charger would not charge the battery, yet our charger instantly starts charging. This is a game-changer and could save you hundreds of pounds otherwise spent on reviving cells or even purchasing a new battery!* The other advantages of this kind of charging method are that sparking at the point of the charger being connected to the battery is eliminated, while cycle life of the battery can be improved by up to 100 cycles (1 Cycle = 1 charge + 1 discharge of the battery). So Pulse charging is not only safer but also extends the life of your battery. What’s not to like? * Disclaimer – Some Li-ion batteries have more advanced electronics than others, so we cannot guarantee that this charger will charge every single battery on the market that has dropped below cut-off voltage. However, we are of the opinion that providing the battery has some amount of charge, then this should be enough for the charger to recognise and start charging.
