4.0 out of 5 stars
Good product at a good price, poor instructions with contradictions, 29 Dec 2011
Bought this to trickle charge my Harley Davidson motor bike during the winter months based upon the reviews here and of course the price. It comes with a selection of battery connection options which is really good, and has a LED display during operation which indicates the charging status. However it may not suit my application as in the instruction manual it states..
1. "The battery should be disconnected during use" (I want to leave mine connected to the bike)
2. "Do not leave the charger unnattened for long periods of time" (I want it to maintain the battery charge during the winter months)
3. "When chaging is complete unplug the AD/DC power adaptor" (I want to maintain a battery and the bike alarm etc over a period of time)
This appears to be contradicted later in the instructions by the statement that "The charging and discharging process will stop and start in a continuous state. In this way, even if the trickle charger is connected to the battery for a few months, the battery will be charged and fully active"
So 4 stars from me due to the quality of the instructions and the obvious contradictions in the specification and mode of operation
The minimum charging capacity for the battery is 7Ah, not stated in the instructions but indicated on the charger, so check before you purchase this item.
For those that dont know when connecting the unit connect the red (+) first to the positive terminal and then the black (-) next to the negative terminal before connecting the unit to the mains supply. When disconnecting isolate the mains supply then disconnect the black (-) first and then the red (+).
