A "must have"
these days is the MicroVAT Battery, Starting, and
Charging System Tester
advantage of new Impedance/Current test technology to detect the full
range of battery failure modes including bad cells, sulfation, internal
shorting, and other chemical and physical failures. Testing takes less
than five seconds and works on batteries discharged down to as low as one
volt. This saves you valuable time by reducing lengthy charge and re-test
diagnostic tests, plus detailed test data for expert-level
test of battery, alternator and starter in under a minute.
Detailed test data:
alternator ripple, internal resistance, starter draw, state of charge,
charging amps, and volts.
load for accurate alternator test under loaded conditions.

And while we're on the topic
of batteries... it's time to get a "Smart Charger"
When your 12 volt
battery goes dead, a jump-start is only a quick fix for the problem that
may reoccur. The solution is to recharge the battery, using a Smart Battery Charger.
There are several brands available. The two chargers I own are not from
Black&Decker however they seem to work/look very similar.
The Smart Battery Charger is fully automatic and electronic, with a
Digital Smart microprocessor control and an LED indicator for selecting
your charging rate. The three stage automatic rapid charging operates at
40 amps, 20 amps, 10 amps, and 4 amps, with an average 5 minute engine
start time and 4.5 hour full battery charge.
The Smart Battery Charger features 3-stage recharging
This device also features a reverse hook-up warning
The LED display lets you know when the battery is fully
Works with Any Boat
The Smart Battery Charger is ideal for any 12 volt lead-acid battery
types, including those that power cars, boats, lawn mowers, RVs, ATVs and
It uses a 3-stage automatic high-frequency charging technology to build
the battery back up to its normal output level, making it more efficient
at charging than conventional model chargers.
The Smart Battery Charger also has a spark-resistant reverse hook-up and
overcharge protection circuit built into it to insure that the clamps are
not accidentally affixed to the opposite terminals, which would damage the
battery. The automatic float mode monitoring tells the unit when the
battery is ready to avoid overcharging.
Many models have a de-sulfate
mode that can help restore an older battery to almost new performance. The
process can take a day of more however, it is fully automatic and built in to
charge the battery after the de-sulfate process has completed. If the process
can not be completed the charger will give an error code of why the battery can
not be charged properly.

If we post it, we'll send you a Nautical brass key chain that sells for
$10 to $15 at most boat stores. If you have a picture, that's even better.
