Ok, I know this is a bit far off the subjects here but I thought I would see if some of the pro's had any ideas. I tried to start DW's quad (used as a farm implement to rake the horse arena) and no go.I had checked the % charge on the DieHard prior to jump attempt and it said 99%. Did not measure quad battery. Any way now DieHard says 10% and will not charge from wall wort! Any suggestions, other than pitch and buy a new one? Wall wort is putting out expected voltage 17V.

I have no idea what a "wall wort" is however the 17 Volt wall charger for the 1150 system only puts out 1amp when charging it will take allot of hours to bring the jump start battery back to full charge. recharge the battery with a normal battery charger and see if it will hold a charge. A battery can show full voltage but not have any power to start a piece of equipment. you might want to take the battery to someplace like auto zone and have them put a load test on it before buying a new one.

It's wall wart (like a wart on the skin)Wall wart

Sorry for the spelling error. Wall wart is a slang term for the "wall charger". I assume that I could use a higher amperage battery charger once I removed the battery? Then down to auto zone for the load test. I guess I will try to tear down to unit to get at the battery.

Many of these things use a utility battery. I fitted an AGM UL1L to his jump starter and he claims "10-times the power!"Don't know about -that- but if the voltage regulation circuit still works I'd think about it. A cheapo battery is always -the weak link- in those critters.

^^^ Yeah. I have a Harbor Fright pack that's Start, Power Outlets, Work Light and Air Compressor. My guess is a replacement battery would cost as much as a whole new unit, at least on sale. Till then, it's very useful to have around.

AT A BARE -----MINIMUM...

A power pack would have to contain a UL1 L or R AGM battery.

I had one long ago which had the 12AH battery inside. It helped start my 5.2l V8 on numerous occassions, and other vehicles as well, but one day it could not start a 2.0 I4.

I'd had a aux battery by then, but I saw I could have replaced that 12AH agm for about 24$

Here's one for 28$ with free shipping.

Probably sitting on the shelf for years and is 40% charged and sulfated.

Yeah, the couple I've dissected had a 12AH SLA battery inside. Combine that with the 16 ga. wire used to connect to the jumper leads, and you won't do much car starting with it.

I went through two of those portable boosters. One had a built in 120 volt inverter, which was handy. Neither one ever successfully jump started a vehicle. The batteries are just too small. Now I just keep an old full size battery around for boosting.

I guess I could use it to power a small radio for a few minutes. :(

jrnymn7,

The Paisley shirt crowd rates 900 amps by laying a copper bar across the 2 terminals. It will, it really will give 900 for a quarter second before the sucker goes off like a grenade.

I recently bought a Peak Performance power pack, (900 amp), and it couldn't even turn over my 4.0L six banger.

Tried charging the battery and no go! Ordered a replacement battery and hopefully everything will be good. Truth be known we usually only use it to power the sat. finder and a portable dvd player for the kids as well as a jump for the quad. But keeping the DW content means I enjoy fishing that much more.

Thanks for all the feedback! I got to the battery. Negative terminal had white powder build-up. Voltage from the wall charger was good to the battery so I will try charging the battery remotely!
Thanks!
