characteristics of the connected battery, in the range of 0.4A to 5A, by the ampmatic ™ output control circuit .
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 is not intended for use by persons (including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge, unless they have been given supervision or
instruction concerning use of the appliance by a person responsible for their safety. Children should be
supervised to ensure that they do not play with the appliance.
USING THE OPTIMATE LITHIUM
CORRECT USE:
Use the charger only if the input and output leads and connectors are in good, undamaged condition. If the 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:

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 safe T program limits charge current if the voltage is below 12.8V and the
ampmatic
™ 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 will be affected by ambient temperature. The safe T program limits charge current if the temperature measured at
ampmatic
the OptiMate Lithium is below 0 C / 32 F or above 45 C / 113 F. Within the normal temperature range the
™ LiFePO4
specific program automatically determines the most efficient rate of charge current for the connected battery, according to its state
of charge, state of health, and electrical storage (Ah) capacity. The delivered current may be anywhere from 1.25A to 5A.
Charge time on a flat but otherwise undamaged battery:
For batteries rated from 2.5Ah to 5Ah: 60 to 120 minutes to progress to the voltage retention test.
For batteries rated above 5Ah: slightly less than 25% of the battery's Ah rating, so a 50Ah battery should take no more than about
12 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 #6, 7 and 8 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 1.7W, equivalent to power consumption of 0.042 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 0.060 kWh or less per day.
