![]() 4 x AA for a toy, means that the cells will discharge simultaneously. When the batteries are grouped together for a device, e.g. Do not use batteries at high temperatures as this increases the internal pressure inside the cell, which includes liquid loss and a shorter life span. ![]() This will ensure that there is no possibility of over discharging the batteries, which is a major cause of cell damage. In theory, batteries should be recharged when 70% of their capacity has been consumed. Leaving empty batteries in the device for a long time without charging them will cause serious damage to the cell electrode (over-discharge) and will shorten the battery life, so avoid doing so.We recommend recharging the battery when you see signs of decreased performance, for example when luminous energy becomes low when used an LED light. Continuous over-discharging causes damage to the batteries. Recharging the battery 2-3 times can remedy this problem, but if it persists, unfortunately your battery’s life is at an end and we recommend seeking a replacement. For example, use in a low-current-draw LED light until the battery runs out can cause it to over-discharge, and later the battery won’t recharge correctly. If this happens, clean the terminals with a dry cloth.Īppliances without an over-discharge prevention function can sometimes cause batteries to over-discharge. This causes the electrical resistance on the surface of the electrode to increase, which affects battery performance. ![]() Touching the battery with your fingers may leave dust or grime on the surface of positive and negative terminals. In the event your charged battery cannot be used, it’s possible that the batteries were not charged properly or the batteries have discharged because they were kept in use for too long. It is pre-charged when you purchase, but once drained it needs to be recharged in order for you to use it again. Operating time varies according to equipment. *5 Operation time will be shorter than that at room temperature. *4 As part of our participation in the Green Certificate system, we use solar power to charge eneloop batteries prior to sale. *3 Capacity retention based on testing method established by IEC 61951-2 (7.3.2) when stored at 20 ☌ (based on Panasonic’s estimation) and compared with minimum capacity. *1 Battery life based on testing method established by IEC 61951-2 2011 (7.5.1.3).
