The drain on the battery is easily checked with a digital multimeter, set it to the DC CURRENT position and initially a 2 amp scale, then remove either the lead on the battery, and connect the meter in series with the battery and the disconnected lead, you should get a reading of 0 amps (or milliamps). If you get a reading, then yes you have something draining the battery. The problem I was solving related to over charging the battery which can also shorten the life of a battery.
