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 Tech Support Dept. at:
[email protected] or call our toll-free technical
support line 800-379-5579 x206 (Eastern Time) (USA & Canada
ONLY). 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 unit 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 an extended period at high
temperature (>=80°F).
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 24.8 Volts or lower.
Testing a Filler Cap Lead Acid Battery
1. Carefully remove all filler 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
