The LLOYTRON Ultra Fast Intelligent AA / AAA LCD Home Battery Charger is compatible with many battery sizes and will charge up to 4 AA or AAA sized batteries. Rechargeable NiMh batteries can be charged; save money and reduce waste without the need for disposable batteries. The intelligent microprocessor with LCD display screen shows an individual status display for each battery to determine how charged it is.Recharge your batteries to their full capacity quickly and safely. Simply plug in to a standard UK mains socket and insert your rechargeable batteries into the appropriate sized compartment. The LCD display will flash to indicate the battery is charging and show a progress status for each individual battery. Once fully charged the battery symbol will become static and the backlighting will lower. To calculate the charging time the battery capacity must be divided by the charging rate and so is dependent on the batteries you require. The charging rate for AA is 1.2v DC 1800mA (1 battery), 900mA (2 batteries), 450mA (3 batteries) or 450mA (4 batteries) and for AAA is 1.2v DC 900mA (1 battery), 250mA (2 batteries), 225mA (3 batteries) or 225mA (4 batteries).This durable battery charger is long lasting to give power to your family's devices time and again, with many batteries able to recharge up to 1000 times. The safety features such as over charge protection and reverse polarity protection/automatic short circuit protects the battery against current fluctuation, although it is advised not to leave batteries charging for over double the amount of time they require to reach full charge.
