Hawker batteries

[corvette9]

Whats the deal with Hawker batteries? Are they a gel type battery? Is there anything you need to do diff. to charge them?

I ask because the 5 ton cargo I bought last week is now home. It is an RR rebuild done 11/11. The truck is like new. The batteries are fine and it started right up yesterday in 20 degree weather. I lifted the seat to check out the batteries and they are all Hawkers. These batteries have some great cranking power. I just don't know anything about them.

They are sealed lead acid. Great batteries, look up 6TAGM, that is generic type, they do have special charging instructions.

Is there a problem with that link? I can't get to it.

Hawkers are great but not killable. I have a dead one and the price paid for new ones will kill you also.

I just bought two new NAPA Commercial for one of the Deuces this morning. $280 including tax.

Might be nice to have Hawkers but I like money.

I've gotten a bunch of bad hawker batteries lately. I have four on a desulfating cycle right now as a matter of fact and not sure they will pull through.

Great battery but only if you can get them at right price. I have a 2001 that's still kicking strong but you must charge them as there site recommends and they are a AGM type battery.

They are agm. It's glass mat it's like an optima battery. If they are dead you can give them a 20 amp charge for 20-30 hours. They may not even appear to start taking a charge for the first day. I have had ones from 2004 that still worked fine.

Hawkers need high amps to recharge.

Hawkers need high amps to recharge.

But also constant voltage (not over 14.4 volts). If your charger increases the voltage because of resistance/'dead cell', it will cook the battery.

Correct, SCSISCSI

But also constant voltage (not over 14.4 volts). If your charger increases the voltage because of resistance/'dead cell', it will cook the battery.

That is not what it says in the website or the TB. TB said 14.4 was minimum 15.2 high and 10 amps minimum.

I have an email from a Hawker FSR that details how to charge them. I will repost it here shortly.
