Review title: Not good on AGM batteries, and causes some TV interference.
Product review: This B&D; float charger seemed to work OK on standard 12V automotive-type lead-acid batteries, but not on AGM types (sealed Absorbent Glass Mat, similar to GELs), although the box says it is also good for maintaining AGM and GEL batteries. When I tried it on an AGM the initial charge cycle was OK but then the following float charge dropped to at least 1 to 1.5 V less than what an AGM needs, resulting in a long-term undercharge while in maintenance mode. This will result in damage to AGM batteries, and probably gel-cells also.TV interference: while charging a battery it causes some picture hash on the lower channels of nearby TV sets that use an antenna, unless it's re-located far away from the antenna (this might not happen with TV's that are connected to cable or satellite systems). Well designed equipment should not have these problems. It was made in China, not here, which seems to explain a lot about quality these days.
