forms, diamond and graphite, are crystalline in structure, but they differ in physical… Graphite is used in pencils, lubricants, crucibles, foundry facings, polishes, arc lamps, batteries, brushes for electric motors, and cores of nuclear reactors. What are the five uses … Continue reading →

Properties and uses Graphite has delocalised electrons, just like metals. These electrons are free to move between the layers in graphite, so graphite can conduct electricity. This makes graphite useful for electrodes in batteries and for electrolysis. The forces between … Continue reading →

Graphene’s high electronic conductivity, transparency and flexibility make them useful in heterojunction solar cells, where they can be employed in many different ways including electrodes (both anodes and cathodes), acceptor layers, donor layers, buffer layers and active layers. Can graphene … Continue reading →

A basic charger usually charges at around 2 amps – and so needs 24 hours to deliver the 48 amps needed to fully charge a flat, 48 amp hour battery. But there is a wide range of chargers with different … Continue reading →

Typically, the best way to charge your RV batteries from a campsite or at home is to use your shore power cord plugged into a 120-volt outlet (like the shore power pedestal or wall outlet). Can you charge RV battery … Continue reading →

How do you make graphene from carbon? First, pour some graphite powder into a blender. Add water and dishwashing liquid, and mix at high speed. Congratulations, you just made the wonder material graphene. This surprisingly simple recipe is now the … Continue reading →

A graphene-based sensor for detecting gas molecules works by measuring alterations in the electrical conductivity of the material. Graphene-based gas sensors operate by adsorbing a gas molecule on the graphene’s surface, which acts as donors or acceptors of electrons. Why … Continue reading →

You can easily use your alternator to charge your second (auxiliary) battery simply by connecting the positive terminals of both batteries so that they’re in parallel. What charges the auxiliary battery? Electric Vehicle Auxiliary Battery The auxiliary battery is not … Continue reading →

Never ever connect lithium batteries to PWM chargers ! PWM gives out a pulsating power. That destroys a lithium battery. As someone who has designed a MPPT controller I can attest that MPPT has a pulse output akin to a … Continue reading →

5.0 out of 5 stars Amazing shocks, thanks Rancho! Shock performs marvelously, ride improved drastically over OEM. Installation was easy, just a tip though. Get the bottom in place before you release the shock, otherwise you’ll spend a little bit … Continue reading →

So can a bad starter drain your battery? The short answer is: Yes, it can. It could also drain the battery even faster if you repeatedly try to start your car with a faulty starter. A faulty starter is also … Continue reading →

How to Charge Your Power Wheelchair Batteries Position your power wheelchair next to a standard electrical outlet. Be certain the controller power is turned off and the motorized wheelchair is in drive mode. Plug the off-board charger into the off-board … Continue reading →

Short battery life in a laptop is mainly cause by heat rather than charge / discharge patterns. Batteries with fuel gauge (laptops) should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in … Continue reading →

Leisure batteries should be tested for both voltage and state of health regularly. On many vehicles, voltage can be checked using an on-board battery control panel. If not, you can also use either a multimeter or voltmeter. How can I … Continue reading →
