The DBM is an extremely easy device to use just plug in and read.
The Digital Battery Meter (DBM) is a sophisticated meter using a complex computer algorithm which loads and interrogates the battery to discover accurately, how much capacity remains available. It can be used to determine the health of a battery as well as its capacity. There is no other meter which even comes close to this one in terms of technology, effectiveness and value
Plugging an ordinary multimeter
into a baitboat which is not running in water to work out the state of a battery
is next to useless - a pointless exercise. A battery must be under consistent
load to enable its true capacity to be measured. Failure to do so may provide
a false sense of security...and a drifting boat.
