- Ultra-simple to operate
- 1 to 3 cell lipo & 1 to 8 cell NiMH / NiCd
- Charge current 0.2, 0.5 and 1.0 A
- LED charge indicator for NiMH / NiCd or LiPo batteries
- Delta-Peak cut-off detector for NiCd and NiMH cells
- Switchable Delta-Peak voltage: 5 mV, 10 mV, 20 mV per cell
- Constant current /constant voltage charge process for LiPo cells
- Selectable charge current
- Attractive design

What type/size of battery do you have? It should say a Mah rating on the cover or stamped on the actual batteries.

That charger is a low amperage charger. The Peak is for peaking the cells. A lot of other chargers make it automatic yours you will need to pick the rate of peak.

This was one of the more difficult ones to find a users manual in a PDF for. Here you go: Graupner Ultramat 6 Manual PDF Click Here.

Sounds like a 1500mah Nicd battery. That is an older style battery. That battery is going to be a tough one to use since it will drain fairly fast. Plus if it is aged over a year old and has not bee up kept by charging and discharging it may be crapped out by now. I would recommend reading over your owners manual and if you have questions bring it in to your LHS with the battery and run through it with them. You may find out the battery is not going to work for you. If you do not have LHS close there are a few good electric guys here that will be able to help you out step by step. I am one to buy a more costly charger just so it can do the thinking for me.:blush:

LHS = Local Hobby Shop.

If you "peak" a battery, that means the charger will charge the pack to its maximum capacity. The charger will automatically shut off and discontinue charging the pack..

If it were my pack and charger, I would put it on the highest charge rate and let it cook. The charger will shut off when it's done charging.

Like BTB said, it sounds like you have a 1500mah pack. (mah= Miliamps/hour), this is the capacity of the pack. The higher the mah, the more it's capacity, therefore the longer the pack will last per charge.

A simple rule of thumb about charging...

By charging at 1 amp it will take approx 10% of the packs capacity to charge, in hours..
Example... You have a 1500mah pack, charging at 1 amp will take approx 15 hours to charge (because it's a 1500mah pack).. 2 amps will be 7.5 hours 3 amps will be 5 hours to charge and so on.. Make sense?

I wouldn't charge an old pack much harder/higher than 4-5 amps. Anything harder, it will just "false peak" the pack and could potentially burn up the pack.

After you have that all figured out, I can explain how to "Cycle" your pack to bring it back to life, but that is for another time... I don't want to overwhelm you anymore than I already have. I have "Race" packs, that I found in the Garbage at the local track back in the 90's, that are still in use!!

The more times you charge it and use it, the better the battery will work. To an extent of course.
