Ht1000 6 Gang Charger...Power questions.

firebuff17 · Post by **firebuff17** » Thu Dec 14, 2006 8:04 pm

Would like to get some help with an HT1000 6 Gang Charger. I do not have the model Number because I havnt bought it yet.

I am looking at the likely hood of mounting this in a vehicle. I have the option of keeping it plugged into 120v when stationary, but would like to run it on 12v, so it can charge with the vehicle running.
How much power does this draw when @ full capacity at 120volts?
Do they sell a conversion kit to be able to charge on 12v? If they do, What is associated with this?
Am I able to modify the cord to adapt it to 12v?

Any help would be appreciated.

I woould suggest running a inverter.......a good quality one at that. In my opinion you would be much better off in the long run.....

Although these are HT600's we are talking about.

Thanks for the info. I had thought about an inverter also, but forgot to mention it in the post, and also wanted to see if there was another option out there.

Yeah I am in the process of trying to use one with 12V power. Here is an excerpt from a past post of mine:

Alright so I took it apart and found that there are three wires coming from the power supply. A red, black, and blue.

The red and black measured +12V and the red and blue measured -10V.

I have no clue what the blue is for; has anyone ever just powered this up with +12V?

I plan on putting this inside of a fire engine hooked up to 12V.

So it comes down to finding the purpose of the -10V from the supply. Does anyone have any ideas?

Not the best charger for that purpose, the batteries will get COOKED..
AKA distroyed.

You need a charger designed for 12 to 14 VDC UNATTENDED operation.

Will, could you elaborate on how they will get cooked if I run these on 12V and don't hook up the -10V?

The rack will be in the cab...in Michigan...where its cold...

Not an issue of the lack of a -10 Volt source. That particual charger never quite stop charging. So even after the HT's are fully charged, it continues to supply current to the battery. This is what "cooks" the batteries

Spareparts said it well.

The problem is that these Rapid chargers NEVER quit charging the batteries. Then every time the truck is started the charger resets and puts more rapid charge into allready overcharged batteies.

Result= over cooked batteries.......

Also the -10 volt supply is bias to the charge control circuits and without it the charger probally does not work properly.

Get something like the AdvanceTec AT4-205x-Bank charger.

Thank you for your replies.

I have the model number now. Would anyone be able to tell me which style it is? Slow rate? Rapid only? or rapid then trickle?

Model Number NTN1177A or NTN1177C. I will have to wait to receive it because both numbers were listed.

chipjumper:
What model number charger were you using?

Thanks again

Interesting....

Who makes a decent gang charger for a vehicle that will not cook batteries?

We have lots of money in our budget and I'm interested in all types. We need a gang charger will will accept the battery with the radio attached (I don't want our guys taking batteries off and putting them on a charger, its gonna result in broken battery tabs and probably a broken charger).

The only thing I could think of would be getting a ton of those heavy duty metal mobile chargers.

First, what's your application for this? Is this a piece of apparatus (like a command post) that needs to be sustainable for days on end? Or are we talking a regular engine?

In my opinion, chargers on an engine are a bad idea. There's no way you're going to prevent cooking the batteries, and it's not really needed, especially if you have money in the budget for other alternatives.

I recently set a fire department up with all-new portable radios (Kenwood TK-2180Ks). In the past, they were running shift radios with mobile and fixed chargers... the radios were always getting broken/damaged/lost, batteries weren't properly maintained, etc. This time, we bought enough radios and leather belt clips that every single firefighter has a radio, speaker mic, 2 LiIon batteries, and a charger in their locker. The chief also made it SOP that every member on duty carry his/her radio on their person or very close by (if you're going to bed, the nightstand is acceptable... if you're watching TV, the coffee table is fine... etc.)

With this arrangement, the guys should always have a hot battery sitting in the charger. If the tones drop for something big, they can grab it on the way out the door and have a spare. If something small turns into something big, we can send someone to the station to pick up spare batteries.

Plus, the radios get treated much nicer, since they're assigned to each firefighter. You break it, you get to 'splain why to the chief.

If you want to add one or two mobile chargers to the apparatus for occasional use, that's fine. They should NOT be the primary charging/storage/etc. device for your radios, or you're going to be SOL when you really need them and discover the batteries toasted.
