AUTOMATIC DIAGNOSTIC CHARGER FOR 12.8V LiFePO (LITHIUM IRON
4
PHOSPHATE ) BATTERIES FROM 2.5Ah TO 30Ah:
SAFETY WARNING AND NOTES: IF YOU HAVE NOT YET DONE SO, READ
THE PRECEDING PAGES LABELLED "IMPORTANT SAFETY
INSTRUCTIONS" BEFORE OPERATING THIS CHARGER.
This appliance can be used by children aged from 8 years and above and persons with
reduced physical,sensory or mental capabilities or lack of experience and knowledge if
they have been given supervision or instruction concerning use of the appliance in a safe
way and understand the hazards involved. Children shall not play with the appliance.
Cleaning and user maintenance shall not be made by children without supervision.
USING THE OPTIMATE LITHIUM 0.8A
CORRECT USE: If the
Use the charger only if the input and output leads and connectors are in good, undamaged condition.
input cable is damaged, it is essential to have it replaced without delay by the manufacturer, his
authorised service agent or a qualified workshop, to avoid danger.
Protect your charger from damp and humid
conditions both during use and in storage. Damage resulting from corrosion, oxidation or internal electrical short-circuiting is not covered by
warranty. Distance the charger from the battery during charging to avoid contamination by or exposure to acid or acidic vapours. If using it in
the horizontal orientation, place the charger on a hard, flat surface, but NOT on plastic, textile or leather. Use the fixing holes provided in the
enclosure base to attach the charger to any convenient, sound vertical surface.
:
EXPOSURE TO LIQUIDS
This charger is designed to withstand exposure to liquids accidentally spilled or splashed onto the casing
from above, or to light rainfall. Prolonged exposure to falling rain is inadvisable and longer service life will be obtained by minimizing such
exposure. Failure of the charger due to oxidation resulting from the eventual penetration of liquid into the electronic components, connectors
or plugs, is not covered by warranty.
VERY FLAT NEGLECTED BATTERIES: Pay particularly close attention to the following A
LiFePO battery left deep-discharged for an extended period may develop permanent

damage in one or more cells. Such batteries may heat up excessively during charging.
During the SAVE mode the program limits charge current if the voltage is below 12.8V and the program should detect obvious cell damage
and will automatically suspend charging, but the higher the cell count in parallel the more difficult it is to detect a bad cell e.g. a 5Ah battery
typically has 4 series connected sets of 2 parallel cells (4S2P configuration - total 8 cells), a 10Ah battery has 4 series connected sets of 4
parallel cells (4S4P configuration - total 16 cells).
ALWAYS monitor the battery temperature during the first hour, then hourly there-after.
If at any time the battery is uncomfortably hot to touch or you notice any unusual
signs, DISCONNECT THE CHARGER IMMEDIATELY.
CHARGING TIME
Charge time on a flat but otherwise undamaged battery:
For batteries rated from 2.5Ah to 5Ah: 180 to 360 minutes to progress to the voltage retention test.
For batteries rated above 5Ah: 125% of the battery's Ah rating, so a 30Ah battery should take no more than about 38 hours to progress to
the voltage retention test.
Deep-discharged batteries may take significantly longer. A full charge may not be achieved within the 24 hour charge safety limit. In this
case follow the reset procedure below.
RESETTING THE CHARGE & TEST CYCLE
Disconnect from the AC mains. Wait for the POWER ON LED #1 to go out. Upon reconnection to AC power LEDs #3, 4, 5 and 6 will flash
twice to confirm micro processor health, irrespective if the charger remains connected to a battery or not.
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 (per charging bank), equivalent to power consumption of 0.012 kWh per day. When a battery is connected to the charger power
