The solar panel will transform the sunlight into electricity and store it in the battery. When finishing charging the battery,unplug the solar panel and remove your battery close to your sump pump. Connect yoursump pump to the backup battery with a compatible cable. Test the battery and thesump pump to ensure they both function correctly.
Let''s start with charging. When you plug the pump into the charger, the light will slowly pulse red, orange, or green to indicate its charge level. Here are a few things to try: Charge your pump for a minimum of six hours, even if the power button''s LED has turned solid green. Confirm the outlet is working by charging another electronic device.

When purchasing a battery, check the backup pump manual to find out if the manufacturer recommends a maximum AH battery rating for the pump. BATTERY MAINTENANCE. The battery, being the power source for the backup pump, requires periodic maintenance checks to make sure it is fully charged and operational. The battery voltage
Here''s an idea, bootstrap a boost converter with the battery voltage that you want to charge and then use the output to charge the battery. You, of course, have to realise that this wouldn''t be an efficient way of charging a battery. You''d only probably get less than 4mA net charging current with 70mA input, not really worth it. I''ve done this
An alternative to using two separate power converters makes use of an auxiliary charge-pump circuit. The charge pump operates from the power converter''s main output that provides the system''s primary operating voltage, enabling
Today''s charge-pump ICs meet the demanding requirements of portable systems with improved precision, higher output current, output noise levels acceptable to sensitive RF applications, and battery life comparable to that of some inductor-based designs.

I got back home, and for some reason (I normally don''t worry too much about this) checked my Tandem t:slim pump battery. It read 40%. Normally I wouldn''t do anything at that level, but would let it go for 2-3 days at least. But (again for some reason) I decided to let it charge up while I was at my computer. I plugged it

If you build battery/usb powered electronics projects, often you''ll be in need of a high-voltage power supply. That is a power supply that has an output voltage higher than that catered by the battery. One way to get a high-voltage output is to build a charge-pump using a few components laying around. What''s a Charge-Pump?
Fractional Charge Pump: This type of charge pump generates an output voltage that is a fraction of the input voltage. It''s used in applications where a lower voltage is required. Dickson Charge Pump: This type of charge
A charge pump is a type of electronic circuit that is used to increase the voltage of a DC power supply. It works by using a series of switching elements, such as transistors or diodes, to transfer charge from one storage
Introduction. Most engineers are familiar with boost converters, which step up the output voltage (V OUT) to a value that exceeds the input voltage (V IN).They are also familiar with buck-boost converters and single-ended primary-inductor converter (SEPIC), which can ensure that V OUT is above, below, or equal to V IN as needed for the receiving device..
