What does the OptiMate’s red light tell you?

 

·         OptiMate’s Red LED is to tell you there is a battery problem  - it has 2 main functions: 

The first function is to tell you that OptiMate cannot recover your battery – in this instance your battery will almost certainly be unable to start your vehicle after standing for some time.  OptiMate will detect that your battery is deeply discharged and automatically engage its special recovery mode.  In most cases, as long as there is no physical damage to the battery, OptiMate will eventually break down the sulphation inside the battery and continue its program to charge your battery.  If after a long period of trying, even OptiMate cannot recover the battery, the red LED will light to advise you.  The second function is to warn you that the battery is unable to retain its full Voltage after being successfully charged.  This can be due to various causes: e.g. one or more of the battery's six cells having suffered an internal short-circuit. This is like a "hole in a bucket" allowing the delivered charge to run out of the battery again quite quickly. Other causes are described below.

·         Your OptiMate is fine.  OptiMate charges your battery and then tests it to see if it will hold its charge OK.  If OptiMate senses that the battery Voltage drops, it will “red-light” your battery to warn you that the battery may have a problem.  Even while the red LED is showing your battery is still being charged, so for a while, your battery may still seem OK because of the benefit of this ongoing supporting charge. However the underlying battery problem is sure to reveal itself more clearly when you disconnect the OptiMate!  The red LED will also indicate if OptiMate is connected to a battery on the vehicle and it detects a current load, like an alarm siren or the lights being turned on.  If this happens, reset OptiMate by turning the power off and restart it (only OptiMates 1-3 – see notes above).  OptiMate will also detect any persistent drain in the vehicle’s wiring (above that of an alarm) – to check this, disconnect your battery from the vehicle, restart OptiMate and see if it still goes to red.  If it doesn’t, then your battery is fine but there may be a problem with the vehicle’s electrics - you should ask your dealer to check the wiring.
