Can the Accumate battery charger charge a 12v 64amp Battery?

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?

Yes there is a 12v/24v.

What are the charge ratings in Amps of the chargers on offer?

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?

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?

admin — Mon, 21 Apr 2008 09:20:41 +0000

Yes, no problems charging maintenance free batteries.

Does the high cycle / deep cycle make a difference to the charger?

admin — Mon, 21 Apr 2008 09:19:51 +0000

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.

To calculate approximately how big a battery and inverter you require for your power backup needs in Amp-hours (Ah), enter the power of each appliance and the average length of loadshedding time. The first couple of lines are given as an example; just click in the boxes to replace the values with an estimate of your own power consumption.

5 things to look for in power backup system

admin — Wed, 26 Mar 2008 11:06:33 +0000

Here are 5 things you must look for in off the shelf power backup solutions:

1. If it looks home-made, it probably is. The problem with any home-made product is that you get no guarantee, no long term support, no quality connections and no real thought about the components such as cables that work efficiently and use less electricity.

2. Many Inverters on the Market do not perform as well as the manufacturers claim. Make sure the stated Watt capability is true and correct.

Read the small print to make sure the Inverter actually delivers the correct WATTS for what you require. Mention of advanced filtering is a good sign.

3. Only a proper Deep Cycle battery should be used. It has been designed to charge and drain a load over and over. Car batteries are designed for staring (a quick load) they are not designed for been totally drained of power and then charged up again. The incorrect battery will fail, 100% guaranteed.

4. Make sure that the watts are correct for your application. Always take a little bigger than what is actually required. Buy a bigger unit e.g.if you need 1000 Watts then buy an inverter than can deliver 1200 Watts at least. An absolute must is SURGE Watts, on almost every application when you switch on there is a higher surge of power that the Inverter must cope with.

5. The Cables running from the battery to the Inverter must be of a very good quality – the thicker the better. This is very important as a lot of power is used and a lesser quality cable will get hot and can be unsafe. The connectors, joining the cable to the battery must be strong and sound. The contact must be good.
