The PX74 battery is produced by a number of different manufacturers and as a result is known by a large number of alternative codes, such as: I have a 90W version of these POWSEED supplies that has a clean output right up to the rated 90W. Unfortunately like lots of electronic devices lately, these are currently unavailable: Alpha FM 433MHz Keyfob Transmitter Module SMD – RF Solutions ALPHA-RX433S, The Alpha FM 433MHz Transmitter Module SMD Alpha-RX433S is an extremely cost effective but high Read More » If it's taken your battery up to 15 volts, and it's a modern, regulated charger, it appears to me to be faulty. After 8 hours, no self-respecting modern charger should still be charging at 15 volts. If it's old school, this is pretty normal, and it's time to stop charging.
I take it that the "car battery charger" you mention in your post is an old-school type, which does not have any built-in charge regulation? All you need then is a USB-C power supply – [Ricardo] uses a portable power bank which allows him to use the power supply on the go. It’s a great alternative to a traditional heavy bench supply, and more than enough for a lot of hobby uses. To power the 15v circuit, just cut the power cord on the DC side of your supply, and branch the positive and negative wires over to your 15v circuit, and then connect the base pins on the 2n2222s to the digital pins on the Arduino.So, to answer your question, Yes, 15 volts is too high. Most car alternators, that normally recharge your battery after every start, and provide power while the engine is running, are normally voltage regulated to about 13.8 to 14.0 volts. Up to this voltage and at normal temperatures, the battery will only gas very slightly. Above this, and it will gas increasingly with increasing voltage. This will damage your plates by causing flaking of plate material and shortening your battery's life. Gassing is undesirable. The Avera Retrosa is a new scooty in the market and the price of this battery scooty in India starts at Rs 1.08 Lakh. It gets a 3000-watt BLDC electric motor that derives its power from a lithium-ion phosphate battery. It comes with 5-speed settings and it also gets a reverse mode. The Avera Retrosa has a top speed of 90 km/h and it offers a range of 120-140 depending upon the riding conditions. The battery takes nearly 3-4 hours for a full charge and it comes fitted with disc brakes on both wheels. It gets features like a side stand indicator, LED lighting, a dully digital console, and a battery management system. TVS iQube
At 2-Power, safety is a priority. We only use UL1642 certified cells. All components are separated by insulated fire retardant paper. This prevents components touching and potentially short circuiting. In addition all cells have a rubber separator for increased safety. Flat metal connectors are used which have a low resistance, do not overheat and are less prone to damage. Cheap Laptop Batteries can be Dangerous.

Bajaj Chetak Please Note: A laptop battery is shipped with a small storage charge and you will be required to fully charge your new battery when you receive it. It is recommended to do a 16-24 hour initial charge, followed by 3-4 full charge cycles to calibrate your new battery. Please be aware that batteries have a limited storage life and batteries stored for a period of time without being charged / discharged will damage the cells and void any guarantee. See our Rechargeable Laptop Battery Instructions for more information. Bajaj Chetak is offered in two variants and this battery scooty price in India starts at Rs 1.0 Lakh. It has a full metal body with a premium build quality and it comes in exciting colours. It is powered by an electric motor that has a peak power output of 4,080 W. The electric motor draws its power from a 3 kWh lithium-ion battery. The battery takes nearly 5 hours for a full charge and Bajaj offers a warranty of 3 years on the lithium-ion battery. The Bajaj Chetak has a top speed of 70 km/h and it offers a range of 90 km per charge. It comes with features like a digital console, LED headlights, and sequential LED indicators.

It has a ground clearance of 175 mm and the brand offers a warranty of 3 years on motor and battery. Avera Retrosa The 15V is not a real reading. It's an artifact of bubbles formed on the plates from overcharging, which have by themselves an anode and a cathode. This creates a false" voltage potential that really isn't there. (Well, technically it's there, but the bubbles are acting as tiny cells in series, but have no actual stored potential. A high impedance DVOM is not enough load to break down the bubbles, so you get an exaggerated reading of Open Circuit Voltage (OCV) that is not a good indication of true State of Charge (SOC). The build is a simple mashup, starting with a ZY12PDN USB Power Delivery board. This board talks to a USB-C supply that is compatible with the Power Delivery standard, and tells it to deliver a certain voltage and current output. This is then used to supply power to a pre-built power supply module that handles current limiting, variable voltage output, and all that fancy stuff. It even comes with a screen built-in! Simply slap the two together in a 3D printed case with a couple of banana plugs, and you’re almost done. Once upon a time, building yourself a power supply required sourcing all manner of components, from transformers to transistors, knobs, and indicators. These days, everything’s a bit more integrated which helps if you’re trying to whip something up in a hurry. This build from [Ricardo] shows just how straightforward building a power supply can be.The Ather 450X is one of the most popular battery scooty in India and its price starts at Rs 1.13 lakh. It comes with a PMS motor that has a maximum power output of 6 kW and its peak torque output is 26 Nm. It is powered by a 2.9 kWh lithium-ion battery that is IP67 rated.

It comes with features like a 7-inch LCD dashboard, alloy wheels, reverse mode, and disc brakes. Ola S1 Power laptop batteries are randomly tested in-house as part of a total quality control programme to ensure compete safety. They are also supplied with 12 months warranty against manufacturing defect. Unlike some brands that use Chinese or even refurbished cells, 2-Power laptop batteries only use high quality, brand new components. Your Philips Shaver comes with a customised built-in battery. Do not try to replace the battery yourself. Note, by gassing, I don't mean boiling. Gassing is the breakdown (electrolysis) of water (H2O) in the electrolyte into H2 gas and O2 gas. This happens when the plates cannot accept any more charge (I.e. there is no PbSO4 left to be converted, meaning the plates are fully charged) if the voltage goes too high. A regulated charger will hold the voltage to 13.5 to 13.8 volts once the voltage has peaked, to prevent gassing and overcharging, and the current will drop to almost zero in a healthy battery. Gassing due to overcharging also "uses up" the water in your electrolyte, and in sealed batteries will fairly soon ruin the battery. You may have also noticed that the battery started to get warm/hot. This is another sign of overcharging, and is also damaging to the battery due to expansion and warping of the plates.
