Place the strip of caps [A] loosely over the filler ports,
press down firmly with both hands to seat the strip of caps
into the battery (don't pound or hammer). When properly
installed, the strip of caps will be level with the top of the
Once the strip of caps is installed onto the battery,
never remove the caps, nor add water or electrolyte
to the battery.
Charging the battery immediately after filling can
shorten service life.
Newly activated sealed batteries require an initial charge.
Standard Charge: 0.9 A × 5 ∼ 10 hours

Let battery sit 30 minutes after initial charge, then check
voltage using a voltmeter. (Voltage immediately after
charging becomes temporarily high. For accurate mea-
suring, let the battery sit for given time.)
Charging rates will vary depending on how long the
battery has been stored, temperature, and the type of
charger used. If voltage is not at least 12.6 V, repeat
To ensure maximum battery life and customer satisfac-
tion, it is recommended the battery be load tested at
three times its amp-hour rating for 15 seconds.
Re-check voltage and if less than 12.6 V repeat the
charging cycle and load test. If still below 12.6 V the
battery is defective.
