How does “storage mode” work?
“Storage Mode” is a feature that comes with all Lester Electrical E-series, E-Series II, Summit and Summit II golf cart battery chargers. Once a manual charge session is complete, the charger goes into its “storage mode” feature when it remains connected to the golf cart and the AC Plug remains plugged into the wall. When in storage mode, it will charge your batteries only when the following two situations occur (1) the battery voltage drops to a certain predefined voltage AND (2) 10-15 days have elapsed.
How do I connect the Lester on-board charger to my vehicle batteries?
The positive wire from the charger must be connected to the first positive(+) terminal of the series battery pack (Battery #1), and the negative (-) wire must be connected to the last negative battery terminal of the circuit
Can I use my charger (or the Lester chargers) with a GFCI outlet?
Yes, Lester Electrical chargers have controlled current production so they can be used in application where the AC power sources is controlled by a GFCI wall output
Can I swap out plugs on my 36V or 48V charger?
The DC output plugs used by Lester Electrical have different current ratings, so its important to install a DC Cordset that is rated for the current that can be produced by the Lester Charger. Contact Lester Technical Support for DC Cordset current ratings before swapping DC Plugs
What if my batteries’ voltage is too low, can they still be charged?
There is a minimum start voltage for all Lester Chargers. Lestronic 2 chargers require a DC Battery voltage of at least 70% of the rated voltage to initiate a charge sequence. Newer designed chargers such a Summit or E-Series require approximately 15 VDC for startup
Can I leave my charger plugged in for long periods of time?
Yes, the Lester Electrical Battery Charger can remained plugged into AC power for extended periods of time. It is a good idea to use an AC Outlet surge suppressor if the charger will be left unattended for long periods of time
Does my charger automatically stop charging once the batteries are fully charged?
Yes, All Lester Automatic battery chargers will terminate the charge sequence when the batteries being charged have met 100% capacity
Should the charger make noise while charging?
Ferroresonant and SCR Chargers all use a transformers to produce the current required to charge batteries, so when these types of chargers are producing current, you will hear a low level “buzz” emitting from the charger. Summit and Summit II Chargers are “High Frequency” chargers that do not use transformers, so the LED Lights are used to verify proper operation
Why is my battery charger showing a red flashing light?
Red Flashing lights indicate a fault has occurred during the charge cycle. Quick Flashing (multiple flashes per second) are less critical than slow flashing (once a second) . If the charger is flashing a slow red light, it has terminate the charger cycle and further troubleshooting steps are required
How do I find the owners manual for my charger?
All manuals for Lester Chargers are available on our public website. It may be easier to search for this information using the Charger Series type (Summit II, E-series, etc.)
