Curious ,recently bought a 2008 diesel with 4 hours run time according to dcs remote.
Charged its original battery ( double AA) with charger for 12 hours before operating engine , it started up and ran fine and shut down fine.
Checked dcs and it said low battery but was not alarmed as another diesel from 2011 i have says same thing (always did ) with its MTH original battery fully charged .
Its my understanding reading the forum that this is normal and has to do with the status of the charging circuit and not the battery.
The 2008 diesel however i figured not to chance it since the battery is 5 years old and this morning put in a newly bought BCR2 which was easy to do .
Turned on the old reliable ZW to about 12-13 volts for several minutes then turned on dcs remote and pushed start up selected the engine and it came to life.
After it ran for a few minutes in dcs mode i checked the remote out of curiosity and it said low battery ran for an hour and rechecked it again said low battery.
The instructions that J and W sent with the BCR2 says this "If you are operating in DCS mode (i was ), the battery status will read "HI'.
Any comments appreciated.
