increased battery life and performance. Do not remove the BatteryMINDer from your battery unless you place
the battery back in service.
Failure to keep the BatteryMINDer connected to your battery at all times that the battery is not in service will
affect its performance claims.

Testing Your Battery
It is extremely important that you determine the health of your battery before you attempt to recharge and
recondition it. If any of the cells are shorted (no reading on a hydrometer tester), or the difference in charge
level is greater than 0.50 SG between any two cells (two ball difference if you use a ball-type hydrometer), your
battery cannot be properly recharged and reconditioned. Discard the battery in an
appropriate lawful manner.
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 ET). Be certain to leave your phone number with the area code, time zone
and the best time to call.
Testing a Manifold-type Lead Acid Battery
1. Carefully remove all 6 caps or both manifold-type covers from your battery (3 caps on a 6 volt battery).
2. Check the water/electrolyte level. If the level is low or has ever been below top of plates, severe lead
plate sulphation has taken place. Significant recharge/reconditioning time is needed to restore those plates
to a condition where they can be expected to function normally.
3. Refill each cell with distilled water only to a level of 1/4" minimum over the top of the cell's plates.
