CHARGE YOUR 12 V - 13.2 V BATTERY WITH ANOTHER 12 V BATTERY! NO ALTERNATING CURRENT REQUIRED Charge the battery of your motorbike, ATV or race boat on the trailer on the way to the event.    OptiMATE DC to DC draws power from your vehicle's battery or from an external 12V battery to save, charge and maintain another 12V-13.2V battery. OptiMATE DC to DC's highly efficient long-term maintenance mode protects the source battery and only draws power when the battery to be charged needs it. The OptiMATE maintenance mode keeps the battery fully charged, never overcharges it, extends its life and improves battery performance. OptiMATE DC to DC can save a deeply discharged, sulphated battery at 2 volts.   CHARGING CURRENT: 2 A APPLICATION: Indoor/outdoor (lowest temperature: -4°F/-20°C). SAVE: Start with low voltage of 1 V IDEAL FOR: STD, AGM & GEL 12V batteries and LFP (LiFEPO4) from 3 - 96 Ah. INPUT: 12-16 V, 2.7 A max DESIGN: Weatherproof housing with wall bracket, with 6 ft/180 cm mains cable and 6 ft/180 cm charging cable with SAE plug. Weatherproof battery lead, standard battery terminal kit and battery terminal kit with fuse included.   SAFE: No risk of overcharging. Completely safe for vehicle electronics. Spark suppression. Safe for long-term battery maintenance. Automatic switch-off in the event of a short circuit or disconnected battery. 3-year limited warranty (this warranty is independent of the existing free statutory warranty rights. The statutory warranty rights are not restricted by this warranty).     https://www.youtube.com/user/TecMate1/about       

The most modern 12 V 10 A & 24 V 5 A battery charger in the world! OptiMate 7 12 V-24 V is perfect for 12 V and 24 V starter and deep-cycle batteries requiring accurate temperature-controlled charging and unmonitored, safe long-term expectancy. SPECIAL FEATURES: Tailored to sensitive electronics: The RETTUNGS program is designed to provide a SAFE, fully automatic, low voltage start (starting at 0.5 volts) and IMPULS rescues of deeply discharged batteries connected to very sensitive electronics, such as light aircraft, industrial equipment, etc , Protection against Wrong Voltage Selection: When 24V has been selected and a 12V battery is connected, OptiMate 7 12-24 V immediately warns that a lower voltage has been measured and will not continue charging. The USER must confirm that the rated voltage of the connected battery is 24 V before the RESCUE mode is activated. CHARGING POWER: 10A @ 12 V / 5 A @ 24 V (Ampmatic) USE: Indoor / outdoor (lowest temperature: -40 ° F / -40 ° C). RESCUE: Starting at low voltage of 0.5 V (12 V) + 1-stage desulphation rescue. IDEAL FOR: STD, AGM & GEL 12 V batteries from 3-400 Ah / 24 V batteries from 1-200 Ah. INPUT: Global (100-240 V 50-60 Hz), high efficiency (CEC listed), fully enclosed. DESIGN: Weather resistant housing with wall mount, with 6 ft / 180 cm power cable and 6 ft / 180 cm charging cable with SAE plug. Weather resistant battery lead & standard battery terminal set included. 6 different charging programs: 12 V: 14.4 V (for normal lead acid batteries) 12 V: 14.7 V (for high performance AGM or spiral cells – OptiMa / odessey batteries)12 V: 15 V (for Ca/Ca batteries that need 15 V charge). 24 V: 28.8 V (for normal lead acid batteries) 24 V: 29.4 V (for high performance AGM or spiral cells – OptiMa / odessey batteries)24 V: 30 V (for Ca/Ca batteries that need 15 V charge). SAFE: No risk of overcharging. Absolutely safe for the vehicle electronics. Radio suppression. Safe for long-term battery maintenance. Automatic shutdown in case of short circuit or disconnected battery. https://www.youtube.com/user/TecMate1/about
