TecMate Optimate 7 Select, Instructions For Use Manual

6

Check for unusual signs, such as bubbling or leaking electrolyte, heightened activity in one cell compared to 

others, or hissing sounds. If at any time the battery is uncomfortably hot to touch or you notice any unusual 

signs, DISCONNECT THE CHARGER IMMEDIATELY.

MAINTAINING A BATTERY FOR EXTENDED PERIODS: 

For accurate temperature regulated charging and 

long term maintenance place OptiMate as close as possible to the battery under charge. 

For example, if the 

battery is within a vehicle or craft stored outside in direct sun or cold, place the OptiMate inside the vehicle or craft 

(or its battery compartment) so that charge voltage can be adjusted according to the same environment 

temperature that the battery would experience.

The OptiMate will maintain a battery whose basic condition is good, for months at a time. At least once every 

two weeks, check that the connections between the charger and battery are secure, and, in the case of 

batteries with filler caps on each cell, disconnect the battery from the charger, check the level of the 

electrolyte and if necessary, top up the cells (with distilled water, NOT acid), then reconnect. When handling 

batteries or in their vicinity, always take care to observe the SAFETY WARNINGS above.

NOTES ON TEST RESULTS: 

The voltage of a cooled battery is directly proportional to its State Of Charge 

percentage (SOC%). Immediately following charging a battery may briefly hold a higher voltage, as charging 

raises the temperature of chemical elements within the battery. A battery recovered from a deep discharged 

state may need longer to cool and voltage to settle and reflect its true state of charge (SOC%). 

1.

 For any test result other than green #6 (or green #6 and yellow #7 together if the battery is a STD type 

with filler caps), disconnect the battery from the electrical system it supports, and reconnect the OptiMate. If 

a better test result is now obtained, this suggests that the power losses are partly due to an electrical 

problem in the electrical system and not in the battery itself. 

2.

If the red LED #8 alone, or the yellow #7 & red LED #8 indicate together, or yellow #7 LED alone for a 

sealed battery, a significant problem exists. The battery is unable to retain sufficient charge or is losing 

charge very fast due to connected circuitry. A sudden load being switched on while the charger is connected 

can also cause the battery voltage to dip significantly. 

3.

GOOD TEST RESULT, but the battery cannot deliver sufficient power: Degraded inter-cell connections or 

poor external connection at battery posts may cause severe voltage drop when high current is demanded 

from the battery. Check external battery connections or have battery professionally assessed (load tested).  

ECO POWER SAVING MODE WHEN THE CHARGER IS CONNECTED TO AC SUPPLY: 

The power converter switches to ECO mode when the charger is not connected to a battery resulting in a 

very low power draw of less than 0.5W, equivalent to power consumption of 0.012 kWh per day. When a 

battery is connected to the charger power consumption depends on the current demand of the battery and 

its connected vehicle / electronic circuitry. After the battery has been charged and the charger is in long term 

maintenance charge mode (to keep the battery at 100% charge) the total power consumption is estimated to 

be 0.024kWh or less per day.
