Warning: this is only a resume; you can' t use the JMF236  only with these instructions. The complete information is sent to customers with the machine; including instructions about acid. See also FAQ about car batteries and JMF process

The super battery charger / regenerator JMF236 charges and regenerates from one to twenty 12 or 6 volts batteries. Motorcycles and 24 volts batteries can be regenerate with the JMF236 (See the user manual for precise instructions)

Operate the JMF236 is very easy.  We recommend that you read carefully the instructions and follow the manual step by step.  Before  to operate the regenerator, it is important to know the different components of the JMF236:

Interrupteur = Switch
Controle = Control knob
Amperemetre = Ampere indicator
Indicateur =  Power indicator
Connecteur = Connector
Entrée electrique = Electricity input
Redresseur = Reset

Step 1 : Verification and starting  the JMF236

When the regenerator as been carefully withdraw of his box, you have to:

Adjust the 220-type Gab adaptor at the end of the electric wire of the regenerator.  This adaptor allows you to fit from the North America electric system to the European and African electric systems.  At this step do not connect the regenerator.

Adjust the control knob at the minimum level.  The control knob is the big wheel with numbers.  Turn the knob left to reach the minimum. 

Be sure that the switch is OFF. The switch is located at your right just over the amp. control. To be OFF, the switch must be in the lower position.

The regenerator is now ready to run.  The next step is to check and prepare the batteries. 

Step 2 : Preparation of the batteries

The JMF is able to recharge simultaneously 1 to 20 batteries of  6 or 12 volts. ( For motorcycles and 24 volts batteries consult the user manual) There is no matter how many batteries you are regenerating simultaneously; the charging time is always the same because we are recharging in a serial way. 

Check the casing of the battery.  If the casing have a split or a crack, it is important that you block it with special glue because you won’t be able to regenerate the battery.  (See the user manual to know which glue you have to use). If the battery is rounded, it shows that the battery was charged many times and the heat of the cell did the battery rounded. A rounded battery shows that it is probably an old battery which will not run for a long time. 

Clean the battery posts: see user manual. 

A battery full of sulfur acid will have a better efficiency: check the level of acid with the battery hydrometer received with the JMF236. Complete information about acid and possibility or not to use water: see the user manual.

Battery caps position during regeneration: see the complete manual for instructions

This ends the battery preparation.  You can now start the regeneration process. 

Step 3 : Testing the batteries 

Before starting the regeneration process we highly recommend to test the batteries one by one to make sure that they can receive the charge.

Take to positive (+) connection of the JMF (red) and connect it to the positive battery post.  Do the same thing with the negative (-) connection and connect it to the negative post of the battery. 

Put on the JMF by putting the switch on (ON position).  A red light should lit indicating  the regenerator is functioning properly. 

Turn the Control knob to the right until the needle of the Amp Control reach 4 amp. Let the regenerator work for 3 minutes. The needle should be stable between 4 and 8 amp. If it is impossible get this result, even if the control knob is at the maximum, it means that the battery can't be regenerate. If the needle stays between 4 and 8 amp., you have a good battery that will response favorably to the regeneration process. 

Don’t be afraid to over charge a battery. The JMF will stop the power if the charge goes over 10 amp.  The regenerator is provided with a security mechanism.  You have to press the RESET knob to restart the JMF.  

If during the test you smell a stench (bad odour) or you see smoke coming out from one of the cell, it means the battery is shorted. This battery can’t be regenerated but could be rebuilt if you change the cell.  (JMF offers for export complete equipments for rebuilding batteries.  Ask us for more details if any interest).

If during the test your hear a sound coming out from the battery, it means one of the cells is probably loose.  In this case, the battery can’t be regenerate but could be rebuilt.

Repeat these operations with all the batteries.

Step 4: Plugging the batteries

You have now at least one to 20 batteries ready to be regenerate (6 and 12 volts basis). The next step is to plug the batteries before the regeneration. Make sure that the JMF is not switch on when you start to plug the batteries. To plug the batteries you must: 

Take the positive (+) cable of the JMF and connect-it on the positive battery post of the first battery.

Take one of your connection cable and connect the negative (-) battery post of the first battery with the positive (+) post of the second battery.

You repeat this operation with all batteries.

For the last battery, you take the negative (-) connection of the JMF and connect-it to the negative (-) battery post of the last battery. Now, all of your batteries are connected in a serial way.

Warning ! Be sure that all your connections are well done because you won’t be able to charge properly your battery.  A bad connection won’t brake your JMF.

Step 5 : The regeneration Process

Everything is now ready for regeneration.

Switch on your JMF236.  The red light should lit. 

Turn your Control knob on right until the needle of the Amp Control reach 4 amp.  Let the JMF works for 12 hours.  Make sure during this time the needle is between 4 and 8 amp. If the needle doesn’t move, it means that one of your battery is not correctly connected.  Check every cable and battery post.  

After 12 hours, check the charge of each battery by using your portable battery tester received with your regenerator.  If the charge is lower than 12 volts, regenerate your battery for another 12 hours.  If it shows 12 volts it means that your battery is now ready.  You can remove your battery from the regeneration process. Be careful to re-plug your battery the right way. There is no problem letting your good battery for another 12 hours but it will not become better.

After 24 hours, check again the voltage of your batteries with your battery tester.  If after that time a battery doesn’t reach 12 volts it means this battery will can’ t be regenerate. Meanwhile, this battery can be rebuild .

For the batteries which reach 12 volts, we highly recommend to check the ampere level of the battery. See instructions on the complete user manual.

It is possible, but not necessary, to check the charge of the alternator of the vehicle which will receive the battery.  For details and conclusions about this test see the user manual.

We are at your service to answer to  any question.  We also want to remind you that we offer all the equipments to rebuild  batteries and can offer the training  in any country or in Canada.

Warning
Never smoke or bring close the batteries any fire. Batteries could explode.
