Why does my Schumacher Electric Battery Charger ammeter read less than the selected charge rate?

If the ammeter on your Schumacher Electric Battery Charger reads less than the selected charge rate while charging a discharged battery, it could be due to a few reasons. An extension cord that is too long or has too small of a wire gauge can cause this; try using a shorter or heavier gauge extension cord. A weak cell or sulfated plate in the battery may also be the cause; a sulfated battery will eventually take a normal charge if left connected. It's also possible that the battery is only partially discharged, in which case you should continue to charge it.
