OptiMate is a charger/maintainer that you can leave connected to any battery whicle a vehicle is not being used. Simply attach the pigtail lead to your battery and leave the connector some where for easy connection, on a bike for example, under your pillion seat, behind a panel, a rear foot rest. The lead has a weather proof cover to protect it from corrosion.

 

Simply connect OptiMate after every ride and your battery will ALWAYS be fully charged.

 

 

For more accessories please see SAE accessories page - usb chargers, torches, charge indicators, exptension leads, splitters, sockets and plugs etc

 

Recommended for use with all lithium batteries.

Why use OptiMate Lithium for Lithium batteries?

You’ve bought the performance motorcycle of your dreams. The manufacturer says it runs best on the highest octane premium gasoline / petrol available where-ever you may be riding at the time. Even so, you make it your business to go out and always fill it with the cheapest low grade gasoline you can find.  Come on, 87 is close to 93, so surely a few points of octane cannot make a difference to performance?

Is this scenario likely? NO!  Would you be considered nuts if you did that? YES! 

Then why is it likely that you may buy an expensive premium lithium battery that works at a higher voltage and then charge and maintain it with an old lead-acid charger designed for lead-acid batteries that work at a lower voltage? Surely a volt or so cannot make a difference?

Well, it does, but you might be forgiven as buyers of lithium starter batteries have been fed false information that originates from the assumption that as the lithium battery is replacing the lead-acid in the vehicle it must be charged the same.

Actually, NO!

Unfortunately it has caused many a lithium battery to die prematurely and many riders have ended up on the growing list of disillusioned users of lithium starter batteries.

Let’s set this right  :

Lead-acid and lithium batteries operate the same in the vehicle ONLY within the range of 13 to 14.4V.  Below that it changes : a lithium (LiFePO4) is close to 0% at 12.8V. It has no useful power left to give around the same voltage where the sealed AGM / lead-acid battery is at full charge (12.7 to 12.9V)!

If you want your super light lithium battery to perform as intended, you should charge it with a lithium battery charger!

So, what does a lithium charger do differently and why?

Saving a low volt lithium battery – There are NO lead-acid chargers that can effectively SAVE a lithium battery that is discharged below 8V. In fact, the opposite is true, a lead-acid charger is more likely to kill that weak lithium battery!
A lead-acid charger is designed to deliver high current at low volts, exactly the opposite that a lithium battery needs when completely discharged. A lithium battery below 8V is in an unbalanced and sensitive state, cells are at different resistances. Applying high current will develop different voltages across the cells and the weakest is most likely to develop too high a voltage, which will effectively kill that cell and cause a short circuit. Then there are 3 cells left, each with increased over voltage …..  rapidly there will be none!

OptiMate Lithium’s SAVE mode has been developed following extensive R & D to bring back low voltage lithium cells safely. If a cell had developed damage during the deep discharge OptiMate Lithium will detect that and stop charging, preventing unnecessary overcharging of healthy cells or overheating the battery.

Tip on jump starting a low volt lithium battery - DON’T! As soon as the vehicle engine fires up very high current is delivered to the battery and the unbalanced cells will suffer. Rather SAVE and CHARGE it with an OptiMate Lithium! 

Correctly charging a lithium battery – A fact that no one can dispute – lithium batteries are voltage sensitive, they cannot accept higher than their maximum rated voltage! LiFePO4 cell’s ideal maximum charge voltage is 3.6V, calculating to 14.4V per 4 cell battery. Some advanced cells are able to accept a slight over voltage for short periods of time, up to 3.65V per cell, calculating to 14.6V on the vehicle. Over that all cells rapidly become ‘seat heaters’ and then they die!

OptiMate Lithium’s multi step charge mode is specifically designed to recharge lithium batteries to 100% and no more. The unique pulsing equalization mode removes the need to individually balance cells.

Maintaining a lithium battery – Lead-acid batteries have a higher internal drain which demands a continuous charge to keep them at 100%. Lead-acid maintainers are designed to do that.

Lithium batteries have a very low internal drain and do not need continuous maintenance though. Infact it will weaken the battery over time if this is done. Once a lithium battery is fully charged (100%) it cannot and should not receive further charging.
Best practice is to charge the battery to full and then only recharge it when the charge level has dropped a few points below 100%.

OptiMate Lithium’s maintenance charge mode automatically does that by monitoring the battery charge level and only delivering a charge when the battery needs it.

The SAFE & unique multistage battery optimiser specially designed for 12V LiFePO4 / LFP batteries up to 100 Amp-hours capacity.

OptiMate Lithium 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.

Delivered with two interchangeable SAE connection sets, one with clamps for bench charging, the other with in-line protection fuse and eyelet terminals for permanent connection to the vehicle’s battery to allow easy reconnection of charger when necessary.

Optional accessories include additional fused permanent connection leads (O1); cigarette lighter plug lead (O2) to charge via the cigarette lighter or DIN socket (as found on some BMW, Honda& Triumph touring motorcycles); 1.8m and 4.6m extension leads, weatherproof sockets to provide a convenient 12V supply for sat-nav, MP3 player, mobile phone charger, PDA etc. and much more. 

3-year warranty.
