**New** OptiMate 4 Dual Program - This unique 6-step battery optimiser is specially designed for modern 12V starter batteries from 2.5 to 28 Amp-hours capacity. Ideal for motorcycles, ATVs, jet-skis AND MX-5's with either the original Panasonic Gel Battery, or our WestCo Glass Mat Battery!

Since it's launch in 1995, the unique OptiMate has received wide acclaim as an outstanding compact automatic charger, maintainer and recoverer for 12V starter batteries of motorcycles, ride-on mowers and similar seasonal vehicles, as well as for sealed lead-acid gel and deep-cycle batteries used in back-up power supply applications. Now OptiMate 4 Dual Program takes the proven OptiMate interactive charging programme another step further. Unlike the previous Optimate 4, this new version has a user friendly initial battery condition test on connection, to give an instant indication of battery condition prior to charging.

The connectors of the charger output lead as well as the eyelet and clamp leads all feature integral “glide-guides”. These serve 2 purposes – to help weatherproof the cable entries and to hold the connector pins in exactly the right place. This means that there is now no possibility of the pins to becoming mis-aligned, something which was possible in the past and is still the case with
competitors’ connectors.

Electronic improvements are wide-ranging. Inside the new housing is a completely new electronic circuit board. The new OptiMate 4 is much more efficient than the OptiMate IIISP which it replaces. It delivers 33% more charging power but consumes less electricity, which also means less heat is
generated as a result.

The enhanced electronic functions are now controlled by a microprocessor, which allows additional stages and monitoring controls as well as an expanded and more precise end-of-programme test for power drain. An improved control panel explains the test results and general operation to the user much more intuitively than previously.

Diagnosis of deep-discharge or light sulphation; automatic recovery phase with precisely controlled parameters to recover many neglected batteries, even from as low as 2 Volts.

Multi-stage automatic charging programme monitors and controls both voltage and current while charging the battery to ensure optimum charge for the battery, without any risk of over-charging. OptiMate 4 is totally safe even for long-term connection.

Automatic double-check ensures that the battery is fully charged before switching over to maintenance (float charge) mode. If the check indicates that the monitored signals suggesting full charge were premature, the charger reverts to the main charging stage and continues this procedure until the battery is definitely fully charged.

Hourly checks (in maintenance mode) for any signs that the battery is not able to hold its charge or that it is being drained by something connected to it. If all is well, the green LED indicates after the first of these hourly checks and continues to do so unless something subsequently causes the battery to fail a check. Should this occur the red LED will indicate a "suspect" condition but the charging circuit will continue to support the battery until disconnected.

Automatic cancellation of charging programme when mains power fails. On restoration of mains power the battery is automatically re-assessed and the charging programme appropriate to the battery status is immediately restarted.

Automatic resetting of charging programme in case of accidental loss of contact between charger and battery terminals. If this happens, the circuit will automatically sense the fact and within 7 seconds it will disengage - the charge programme will start afresh on reconnection. OptiMate 4 is totally automatic and fully protected against user errors. There are no switches. Short-circuiting the charger output resets the programme, without sparks or blown fuses. Affordable, compact, intelligent and forgiving of errors,

OptiMate 4 is the perfect tool for regular or long-term maintenance of batteries not in daily use.

The REAL & unique 5-step battery optimiser specially designed for all modern 12V starter batteries from 2.5 to 28 Amp-hours capacity.

Diagnoses, recovers, charges, checks & maintains your battery automatically for months. All major battery manufacturers recommend maintaining starter batteries FULLY CHARGED during periods of non-use. OptiMate 4 is totally safe for months-long connection and maintenance of irregularly or seasonally used batteries even while still connected to the vehicle. The sophisticated charging algorithm ensures no risk of over-charging.

Suitable for all types of rechargeable lead-acid batteries: filler cap types; absorbed acid "MF" for motorcycles; valve regulated (VRLA); & GEL-electrolyte types. As simple as 1-2-3: Just connect the OptiMate Ill to your battery, the rest is automatic. Electronically protected against user errors. There is no switch, no fuse and there are no sparks.

We now have available additional charger leads so you can have a permantly wired plug on another vehicle, click here to see!
