I need to replace my battery charger for my twin Trojan T-105 batteries. Ten Tec recommends an automatic 10 amp charger but I have read on the LIST that some have had great success with the Battery T

Those all work if they have good voltage regulation to not overcharge the batteries, but the low current chargers and battery tenders probably won't keep up with conversational use of the amp. Maybe
I agree. I use a 10A supply to recharge a deep discharge Costco battery that runs my K3 and a few accessories. It's enough for that power level, even during heavy contesting, but I'd want more like 2
My shack DC buss is powered by a large deep cycle 110ah battery maintained by a 75a inverter/charger from a motor home. You may find these devices from Todd engineering as an example. _______________
A battery charger which could provide one tenth of the current needed to run the amplifier could be sufficient if the amplifier was only operated with a 10% duty cycle and the battery discharge/charg
Jim, You are asking what kind of battery capacity you need to run the Herc from just batteries, or a PS + deep cycle in parallel? Maybe this is not what you what, but it might be useful anyway. * Wit

According to the Herc II manual it draws 80 to 100 amps for 1 KW input. Batteries last even better if the discharge is less than 50%. 73, Jerry, K0CQ _______________________________________________ T
Absolutely! I know that with CW you are actually looking at a 50% duty cycle but I'm not sure about SSB. A pair of 6 volt batteries will handle several hours of SSB at 100 watts, but we are talking

I think the Trojans are about 120 ah. So they in theory would supply 80 amps for 90 minutes continuous. Longer loaded time if loaded intermittantly. But they survive much longer if less than half tha
That assumes that you transmit 100% of the time, which is certainly not the case. Rather, most of us listen more than we transmit, except, perhaps, during contests. So for CW, a duty cycle on the ord
