Can the Accumate battery charger charge a 12v 64amp Battery?
April 30, 2008
Do you want to recharge flat batteries or maintain a battery? The AM6/12 is a 1.2A charger the AM PRO is a 6A charger. They can both do the job, it depends on how long can you wait ( how fast you need to charge).
The formula for working out how long a charger will take to recharge a battery from 100% flat state is.
The batteries Amp Hours x 0.7 devided by the chargers charging current in amps. e.g. using your figures - 64ah battery x 0.7 = 44.8 devided by (AM6/12 charging current of 1.2 = 37.33 hours.
If you use the AM PRO 6A then = 64 x 0.7 devided by 6 = 7.46 hours. Remember this is to charge up a 100% flat battery.
The AccuMate 6/12V or the AccuMate Pro 6A can both charge a 64ah battery. If you are looking to recharge flat batteries then the AM PRO 6A is the better option as the AM 6/12V been a lot smaller would take much longer.
If you are however just wanting to maintain your 64ah battery the smaller AM 6/12V will certainly do the job. If you let us have some more information on your exact application we could advise further.
Do you have the smart charger in 24 volt?
April 22, 2008
Yes there is a 12v/24v.
What are the charge ratings in Amps of the chargers on offer?
April 22, 2008
Optimate IIIsP is only 600ma this is for maintenance. The AccuMate 6/12V is 1.2amps also for maintenance and small charge situations. The AccuMate Pro 12 V 6A is a 6 amp charger but has a special charging algoruthym suited for charging big batteries.
When power is restored after an outage, do the chargers automatically revert to the charge-mode? What is the full range of your chargers in Amp ratings?
April 22, 2008
The chargers are intelligent enough to test the condition of the battery when power comes back on and then the charger will go into the correct mode - bulk, absorb or maintain. Optimate III is only 600ma this is for maintenance. The AccuMate 6/12V is 1.2amps also for maintenance and small charge situations. The AccuMate Pro 12 V 6A is a 6 amp charger but has a special charging algorithms suited for charging big batteries.
Can you charge maintenance free batteries with this charger?
April 21, 2008
Yes, no problems charging maintenance free batteries.
Does the high cycle / deep cycle make a difference to the charger?
April 21, 2008
It does make a difference as a high cycle battery needs a different charge than a deep cycle battery. However, our charger is intelligent enough to recognise the difference but still do the job. Therefore our charger will charge both.
I have a 105amp high cycle battery. Can this connect to the battery while the inverter is connected or must it be manually changed over during a power outage?

No you don’t have to disconnect the battery charger as the TechMate’s intelligent circuit makes provisions for power cuts.
