With OptiMate 4 Dual Program you can now either charge the battery direct, or select the program to charge via the 12V port on CAN-bus equipped BMW motorcycles (using an optional DIN plug lead).\u003c\/p\u003e\n\u003ch4\u003eHow it works\u003c\/h4\u003e\n\u003cp\u003e1.       \u003cstrong\u003eSwitch between STANDARD or BMW CAN-BUS program\u003c\/strong\u003e with a simple procedure: connect clamps together, connect to mains, wait for the LED’s to confirm program change, disconnect clamps. LED indication confirms the BMW CAN-BUS program is active. Once selected, the chosen program is saved as the default mode for next use, but you can switch programs as many times as you want.\u003cbr\u003e2.       \u003cstrong\u003eSafety check:\u003c\/strong\u003e OptiMate 4 DUAL PROGRAM will proceed to charge if the battery voltage can maintain above 2V during the initial start up diagnosis, even if the battery was at 0.5V before connection.\u003cbr\u003e3.       \u003cstrong\u003eFunctionality:\u003c\/strong\u003e OptiMate 4 DUAL PROGRAM microprocessor checks the system for correct operation (LEDs flash briefly to confirm).\u003cbr\u003e4.       \u003cstrong\u003ePre-qualification test:\u003c\/strong\u003e OptiMate 4 DUAL PROGRAM indicates the battery condition prior to charging.\u003cbr\u003e5.       \u003cstrong\u003eDesulphation and recovery:\u003c\/strong\u003e STANDARD (up to 16V) engages automatically to recover neglected, flat batteries from a sulphated to a chargeable state. For badly neglected batteries the TURBO stage (max 22V) engages if vehicle electronics are not detected or the battery is out of the vehicle. The turbo stage is disabled in CAN-bus mode. The safe low voltage PULSE recovery engages for the final 15 minutes.\u003cbr\u003e6.       \u003cstrong\u003eBulk charge:\u003c\/strong\u003e a constant current of 1A is delivered until the voltage reaches 14.3V.\u003cbr\u003e7.       \u003cstrong\u003eAbsorption and equalisation:\u003c\/strong\u003e Current is delivered in pulses to bring the battery to full charge in the shortest possible time.\u003cbr\u003e8.       \u003cstrong\u003eCharge verification and short circuit \/ dead cell check:\u003c\/strong\u003e Charge acceptance is monitored, to detect internal damage and prevent unnecessary charging of an unrecoverable battery that cannot be recovered. An undamaged battery requiring further charging will revert to pulsed absorption.\u003cbr\u003e9.       \u003cstrong\u003eVoltage retention test:\u003c\/strong\u003e is conducted for 30 minutes during which no charge current is delivered, with 5 possible test results indicating the battery’s general state of health. The pre-qualification test can be used to detect batteries that may hold a charge initially, but lose charge overnight.\u003cbr\u003e10.    \u003cstrong\u003eCharge maintenance:\u003c\/strong\u003e a voltage of 13.6V is delivered for 30 minutes following each voltage retention test, with sufficient current to sustain it against natural self-discharge or drain from permanently active vehicle components or connected accessories (alarm, immobiliser). The voltage retention test and charge maintenance periods continue alternating half-hourly until the battery is disconnected. The test result is updated during each subsequent test.\u003cbr\u003e11.    \u003cstrong\u003eCAN-bus program:\u003c\/strong\u003e the KEYLESS activation program guarantees automatic re-opening of the connection even with the ignition turned off. 12.    The alternating test and charge maintenance program is designed to provide the recommend maintenance voltage for AGM \/ GEL batteries whilst reducing the average voltage as required by STD filler cap batteries, making it ideal for indefinite and 100% safe long term maintenance charging of any type of 12V lead-acid battery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended for: \u003c\/strong\u003eAGM\/MF, STD, GEL and spiral cell batteries from 2Ah to 50Ah\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLong term maintenance: \u003c\/strong\u003eUp to 75Ah\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProgramme control: \u003c\/strong\u003eMicroprocessor, 6 stages, fully automatic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput current max: \u003c\/strong\u003e0.15A @ 230V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTypical annual energy cost: \u003c\/strong\u003eLess than £1.00 per year (continuous maintenance)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReverse drain current:\u003c\/strong\u003e Less than 0.5mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput current (bulk charge): 1\u003c\/strong\u003eA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic desulphation: \u003c\/strong\u003e2 stages (recovery and Turbo-recovery)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharge time limit: \u003c\/strong\u003e48 hours (maintenance time: unlimited)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaintain \/ test cycles: \u003c\/strong\u003e30 min\/30 min (alternating hourly)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharge retention test:\u003c\/strong\u003e 5 possible results from ‘good’ to ‘bad’\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize: \u003c\/strong\u003e200 x 75 x 61mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight: 1000\u003c\/strong\u003eg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure classification: \u003c\/strong\u003eIP54\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting: \u003c\/strong\u003eEasy direct wall mounting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput cable length: \u003c\/strong\u003e2m\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput cable length: \u003c\/strong\u003e2m\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Accessories: \u003c\/strong\u003eO1 Weatherproof Eyelet Lead; O4 Clamp Lead for bench charging\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation temperature range: \u003c\/strong\u003e-40°C \/ +40°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty: \u003c\/strong\u003e3 years\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe REAL \u0026amp; unique 6-step battery optimiser specially designed for all modern 12V starter batteries from 2.5 to 50 Amp-hours capacity.\u003c\/p\u003e\n\u003cp\u003eDiagnoses, recovers, charges, checks \u0026amp; maintains your battery automatically for months.  All major battery manufacturers recommend maintaining starter batteries FULLY CHARGED during periods of non-use.
