1: Do I need to charge the batteries before using them?A: Yes, you should charge the batteries fully before first using them. 2: Do I need to “brake-in” my batteries?A: Yes, the batteries will need to have a “break-in” cycle consisting of ~ three discharge/charge cycles before they will reach optimum performance. This involves three complete discharge and three complete recharges. After this initial “break-in” cycle the batteries will have maximum possible performance and less line voltage fluctuations under load.3: How long will the batteries hold their charge?A: All the batteries will self-discharge when not in use. The self-discharging rate depends on the temperature at which they are stored. Excessively cold or hot storage temperatures will drain the batteries faster than normal. Ideally the batteries should be stored at room temperature.4: Why should I recharge my batteries at least every 90days (Li-ion) when I'm not using them ?A: Batteries naturally loose their charge over time. To keep the batteries in optimal condition and extend their life. It's recommended that a top-off recharge be performed at least every 90 days.5: What happen if I leave the power switch on longer than 5 minutes?A: If you have left the power switch on or your product has not been charged for a long period of time, the batteries may reach a stage at which it will no longer hold a charge.6:Is it normal that the batteries get warm when recharging?A:Yes,it is normal that the batteries will become warm to the touch during the recharging process. This is because the increase of the internal resistance and less energy conversion efficiency from electric energy to chemical energy.7:How long will my batteries last before needing replacement?A:Average battery life depends on use and conditions. Even with proper care, rechargeable batteries does not last forever.
