QUALIFYING YOUR BATTERY:
Preliminary Requirements
NOTE: The BatteryMINDer has no electrical output unless it is connected to
a healthy battery. Testing the BatteryMINDer with a volt or an Amp meter
without the unit being connected across a good battery will result in a false
reading. If you experience any problems, or are not sure of how to properly
use or connect your BatteryMINDer, please e-mail our technical support at:
[email protected] or call our toll-free technical support line
800-379-5579 x6 (Eastern Time).
Be certain to leave your phone number
with the area code, time zone and the best time to call.
To gain the best result from your new charger and to maximize the life and
performance of your batteries we strongly recommend you qualify (test)
your batteries before attempting to either charge-maintain or desulfate them.
Remember, even if you just purchased a “new” battery it may have been
subjected to conditions that have caused “sulfation” such as high temperature
(>=80°).
NOTE: If your battery is new and you are certain it was not subject to
conditions that could have caused sulfation*, even before you purchased
it, then you can disregard our recommendations for qualifying / testing
your battery, before using the BatteryMINDer.
* Such as high temperature storage (=/> 80°F) and/or allowed to self-
discharge to
37.2 Volts
/
49.6 Volts
or lower.
Testing a Filler Cap or Manifold-type Lead Acid Battery
1. Carefully remove all caps from your battery.
2. Check the water-liquid electrolyte level. If the level is low or has ever
been below top of plates, severe lead plate sulfation has taken place.
Significant recharge/reconditioning time is needed to restore these plates
to a condition where the battery can be expected to function normally.
3. Refill each cell with distilled water only to the liquid level indicator found in
each cell.
Before proceeding further you must be thoroughly familiar
with the safety and operating instructions.
4. Recharge the battery with the BatteryMINDer to ensure that it is slowly
and completely charged before you determine its condition. Allow battery
to “rest” (see
Glossary of Terms) overnight for a minimum of 12 hours
before testing with a temperature compensated hydrometer and/or digital
type voltmeter only.
