OptiMate IIIsp - the unique 2 plus 6-step battery optimiser specially designed for modern 12V starter batteries from 2.5 to 28 Amp-hours capacity.

Now OptiMate IIIsp takes the proven OptiMate interactive charging programme another step further - features include:

· 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. In really difficult cases the interactive programme even gives the battery a subsequent "second shot".

· 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 III 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 IIISP 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 III is the perfect tool for regular or long-term maintenance of batteries not in daily use.

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 III 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 II to your battery, the rest is automatic. Electronically protected against user errors. There is no switch, no fuse and there are no sparks.
