Try jump starting the battery. Li Ion batteries often have smart chargers if the battery gets to low the charger doesnt recognise it. If yo have a spare battery fully charge it ant then conect + to + and - to - with wire ( may take two people) kep them connected for 2 mins or so then try in the charger.

The red light on my mouse keeps on blinking


Here's a guide;
What do the battery lights mean on my mouse? Some keyboard and mouse models feature a battery light that shows the current status of the batteries. The following table describes the different lights and states.
Light
Device Model Status Single long green blink Rechargeable Batteries are good. This occurs when batteries are first installed or every time that the device is turned on. Slow green blink Rechargeable Device is docked in the charging station and is charging properly. Steady green Rechargeable Device is docked in the charging station and does not need additional charging. Steady green Presenter Mouse (Japanese version) Laser pointer is on. Red/green blink Wireless Device is discoverable (trying to connect to the transceiver). Slow red blink Non-rechargeable Batteries are low and need to be replaced. Slow red blink Rechargeable Batteries are low and need recharging. Fast red blink Rechargeable Device is docked in the charging station, but there is a charging error.
Reasons for errors: The wrong type of battery is installed; the battery or batteries are missing; or the battery connection is bad.
Solutions: Make sure that the correct battery or batteries are installed, and are installed correctly. If necessary, remove the batteries, wipe them with a clean cloth, and reinsert them. Steady red Presenter Mouse (Standard version) Laser pointer is on.

What does a orange power light mean


please see the commentary. God bless you

  • The majority of laptops will display a solid green, blue or purple battery light to indicate that the battery is fully charged. Most manufacturers indicate that a laptop is in the process of charging by displaying a solid or blinking green, orange, blue or purple light. If your battery indicator light is green, blue or purple, the battery is probably functional, regardless of whether the light is blinking. If the light is solid orange, the laptop is probably in the process of charging.

Battery Error Coneventions

  • Many battery manufacturers use rapidly blinking lights to indicate that a battery's charge level is low. In general, a laptop will rapidly blink orange or red when its charge drops below a certain level until the computer is plugged into a power outlet and charged. If your laptop's battery indicator continues to blink rapidly in orange or red or if it remains red even when it is plugged into the charger, it indicates a problem with your battery or the charger.

Makita bl1830 charges but stays on static red light


Chargers have been known to lie about what they are indicating. Even though you say the batteries were charged only a hanful of times, they may, in fact, have expired

DC18RA battery loader is not working anymore.


Makita chargers are designed to check a battery before charging them. If both the red and green lights are flashing after you put a battery on the charger, it is reading a problem with the battery and will not charge it. It could be a bad cell, a problem with the circuit board, etc. but as long as it reads the problem it will not charge the battery.

My dc18ra makita battery charger flashes red and green lights no matter how many bateries i try


The pcb inside the battery has a microcontroller that monitor the charges and charge cycle. When the cell falls below a certain voltage, it will instruct the charger not to charge and will show with a red-green flashing light. If the battery has been tried 3 times in succession then the pcb will brick itself from the makita charger. So first replace the bad cells. There are 2 solutions at this moment: charge with a 3rd party lithium charger like the imax b6 or replace the pcb with a working one. check out my blog on http://mkbl1830.blogspot.com/

Battery will not charge, charger flashes red and green


If both lights are blinking on the charger after putting the battery on to charge, the battery is no longer chargeable. Most likely it's bad cells inside the battery, the charger is reading the battery as bad and will not charge it. The only fix is to buy a new battery.

My charger is flashing red when i place the battery in it


Ridgid charger lights read as follows: Solid red; charger has power. Flashing red; charger is evaluating the battery, checking if it's cool enough to charge and if it is in chargeable condition. If the battery is hot, i.e. just came off the tool after extended use, it won't charge the battery until it cools down. Flashing red & green; the battery is defective and the charger will not charge it. Solid red & flashing green; battery is charging. Solid green; battery is full.
