I need a better battery charger than the one that came with our 2003 LD.
Last weekend were dry camped, for five days, under a lot a trees that prevented the solar panels from producing much power. Moving our campsite to a sunny location was not an option. By the time were ready to go home, the Link 10 showed a 230 amp-hour discharge. While this is still acceptable for our oversize battery pack (440 amp-hour with 4- T105s), it took many hours of driving and shore power to bring it back to a full charge.
If we had stayed any longer, the battery would have been discharged to an unacceptable level.
 Our LD has the `improved' 7300 Converter but it still charges at a low level and can take many hours of generator operation to recoup the used amp-hours. It will start out at 45-amps but quickly starts dropping and will be in the low 30-amp range with a half hour.
This is clearly not a 3-stage charger.
Before bumper jumps in and recommends a Prosine 2000 watt inverter with a 100-amp charger, I must say the $1200 price tag, plus installation, is way out of my price range.
 Searching the net, I found a Progressive Dynamics Inteli-Power PD9270C 70-amp converter that will fit where the existing 7300 now resides.
It sell for $208, a much more reasonable price.
http://tinyurl.com/2bybeu> The literature indicates that the charger should provide a high rate of charging until the battery reaches 90% of capacity and then starts tapering off. This sound like a true 3-stage charger.
Has anyone in this group install one? If so, what is your impression?

Thanks

Larry

Larry, see msg# 58869 for Jonna's report on replacing a 7300 series with a 9100 series.  The 9270C you're looking at should even be better since the Charge Wizard is built-in. Maybe Jonna can give a 2 yr. update.
