^I am in full agreement. You need a MANUAL battery charger and leave it on 10 amp mode while scanning, coding, or doing DME updates, it needs to maintain constant voltage during these operations and any AUTOMATIC battery chargers or maintainers will drop off voltage once the battery reaches full charge which could potentially get a voltage drop
