OptiMate 4 Quad Program 12v Battery Charger / Optimiser Reviews

4.8 Rating 11 Reviews
Read MX5parts Reviews

**New** OptiMate 4 Dual Program - This unique 6-step battery optimiser is specially designed for modern 12V starter batteries from 2.5 to 50 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 50 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.

This is so much easier to use than a basic charger so the extra cost is worth it. It lets you know every step of the charge and takes away the guessing. I woukd definitely recommend. Confirmation of questions I had were quickly explained by Mark at mx5 parts who was extremely helpful.

I had another (branded and not cheap) charger/conditioner connected for weeks and when I checked the battery was flat and the charger had a battery fault LED lit. I bought the Optimate 4 and in 2 days I was able to start the car again. Wonderful service I ordered it on line and it arrived the following day.

This is a wonderful addition to my tool kit. It arrived the next day as promised and my battery was on charge in a few minutes. Take your time to read the instructions and the chargers processes as it's all lights and whistles initially. When I monitored it's progress in conjunction with the guide, it demonstrates a complete condition of your battery at every stage. A very useful item.

I know that this may sound like hyperbole but the Optimate charger may be one of the most satisfying gadgets that I have bought. There is just something about the way it does what it does that just feels right. I love it when a piece of kit does exactly what it is meant to and does so in a satisfying manner - and this charger does that.Don't be fooled by its diminutive size - smaller than most battery chargers I have used - it's a good piece of kit. I had allowed my battery to get far too low over the winter and my existing charger couldn't do anything with it. It was either buy a new battery or try an alternative charger. The charger being the cheaper option I went for that. I'm glad I did.When it arrived, I looked at it with dismay. This small plastic box surely couldn't be the answer to my problem. However, it had a good solid heft to it and, having no other option, I connected it up. The charger went through its initial checks and confirmed that my battery was indeed out of charge and damaged. So, heartened by the fact it seemed to be doing something, I left it overnight. When I came back, the lights had changed. Could it have actually done something? I tried turning the key and my 5 sprang into action on the first try.The battery was still registering as not being perfect so I left the charger connected and over the next few days my battery got better and better. My battery now registers as working perfectly (and experience confirms that it is working). I've left the charger on its maintenance program and my 5 is ready to roll whenever I want it to be.Seriously, I really, really like this charger!

La prise de branchement est à 3 broches et comporte un fusible. Il faut donc ajouter un adaptateur (pas facile à trouver et environ 25 €) pour se connecter. Pour le reste ça marche très bien, même si le manuel d’utilisation n'est pas des plus clairs pour un néophyte.

Woo Hoo no more "all dressed up and nowhere to go" episodes since i purchased the Optimate and the Westco mx5 gel battery.My Mk1 mx5 is her reliable old self and one of the loves of my life again. As everyone knows a spin with the top down lifts the spirits better than the fizziest cocktail. :DMy Mother drove her '71 MGB GT till she was almost 80, at 70 i'm trying to follow in her footsteps with my MX5, with parts and good service from MX5parts.co.uk looks like i may manage it.jo moore

Brillant bit of kit and essential if you do not use your Mx5 for long periods. Much better than the Lidle chargers you get (and I had), as these revitilise the battery, if you disconnected from the car first.

This is a super piece of kit that performs exactly as claimed. Very sophisticated recovery/maintenance process that is perfect for Fives that are not used daily. Connection to battery can be left permanently in position avoiding need to remove battery cover each time it needs charging - connecting block just pokes out from under the cover. TAKE MY ADVICE: buy one of these BEFORE you buy a new battery. I bought a WestCo battery in a hurry to get back on the road, realised I needed a good charger and then put it on the old battery which I hadn't yet thrown away. Result: old battery fully recovered and now I have a spare....
