Solar power operates on a very simple concept known as the photovoltaic effect. The sun's rays supply photon energy. When photon energy is contained with electrons in orbit, it knocks those electrons from their orbit and creates electricity. This electricity can then be sent to either an electrical device or battery to be stored or used.
Solar power is an excellent energy source due to the fact that it is completely renewable, and also has a little-to-no carbon footprint in most applications. Power grids may fail, and batteries may run out, but solar power will always be there for you as long as we have the sun - which isn't going away anytime soon.
The Solar Power System Components includes Solar Panels, 12 Volt AGM Deep Cycle Battery, Power Inverter, Charge Controller, Wires, etc. If you want to read more information then click on the following site

Check the loading resistors and capacitors feeding the transistors. My guess is a shorted cap on the drain.

We could use some details as to what you wish to find out. Did you want to know about specs or replacements?

Cosun Group went bankrupt a couple years ago and is being liquidated.

The American arm is Qiao Xing which is CECT in China.

These are not well known in the US so they don't show up on battery replacement guides. See if the battery has a capacity and voltage on the outside. If so, then you may be able to find a compatible battery under a different brandname that will fit inside the phone. Try contacting your local Batteries+ or cell phone repair shop. I've had decent luck with the iRepair cell phone repair shop which is now Cell Phone Repair

Red flashing means it is a non-rechargeable or incompatible battery. The charger is meant for NiMH batteries.

Try a friend's good Eneloop battery. If that flashes red, then the charger probably has a manufacturing defect.

These are all messages that follow overheating. E.nOH indicates that the heat sink has returned to the normal temperature range and the unit can be reset. E. OH indicates that the power module is over-temperature. This could be caused by insufficient air flow at the heat sink. That is caused by dust/dirt. The ventilator could be clogged or the ambient temperature is too high. E. OH2 indicates that the motor protection relay was tripped. Check for dust/dirt and clean any filters. Make sure that nothing is blocking the air flow around the unit.

KEB uses these error mesages on the CombiVert F6, https://www.keb.de/fileadmin/media/Manuals/f5/control/f5m/00f5mebk320.pdf .

I hope this helps.
