I have a Craftsman mulcher model 315.370270. The green recharge light goes on but the battery charge level stays in the red. Do I need a new battery and if so where do I buy it?

It is common for many Braun shavers, that if the indicator light flashes red while the shaver is being used (switched on and running), it means the battery is low and needs to be charged soon.

Below is an example from a manual for a Braun model 7526 shaver. You can search that site for other manuals if this is not the correct one.

This model shaver has 3 indicator lights:
1) Green (Charging)
2) Red (Low battery)
3) Blue (Power cord attached and plugged into the wall)

Download the manual for the model 7526 here: http://www.manualslib.com/manual/20281/Braun-5301.html#manual

"The green charging light shows that the
shaver is being charged. When the rechargeable
battery is fully charged, the charging light
flashes or goes off.

If later on, the charging light comes on
again, this indicates that the shaver is
being recharged to maintain its full
capacity.

The red low-charge light flashes when the
battery capacity has dropped below 20%,
provided the shaver is switched on. The
remaining capacity will then be sufficient
for 2 to 3 shaves."

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.

Both issues might be to the same problem.

First problem number 1... you should try using some AA batteries and try to see if you still get the disconnect issue when pressing the X button repeatedly. If so then you have either a bad controller or you have some interference with your controller and other device that might be messing with the 2.4Ghz radio frequency. (Note: that sometimes metal frames and some wires can also bleed signals.)

If your controller works fine with the AA batteries then the issue is likely your rechargeable battery.

Secondly problem number 2... I have had similar issues with batteries. often times it is just because you have reached your limit with your charging on your battery. If you are an avid gamer then this might be the issue. You might want to try the tweak to getting your charger to work again:

"First insert the play and charge kit a little way in just enough to make a contact but not enough to click into place - light goes red - when light goes green slide it out a bit so the green light on the play and charge kit goes out - The green light on the controller should stay on, count to 2 in you head then slide it back in again like before. As soon as the light goes green to tell you its charged slide it back out again I had to do this 3 - 4 times then as if by magic the light should just stay red and carried on charging."

Hope this helps.

Turn your camera on and look at the battery life after you had it charging for a while. your rechargable batteries may be bad or getting bad. Try trading out the rechargeable batteries or try plugging in your charger on a different outlet at home

When the charger light is changing from red to green that is a indication that it is charging the battery. When the charge is complete the light will stay green until the battery is removed or the charger is unplugged.

When the green light stays on that means the battery is fully charged. The correct charger for that light is a Class 2 Transformer
Model: KA12D120030042U It has a output of 12VDC at 300 mA

Red light indicates that the camera is out of charged., Try to charged your battery for 3-4 hrs if you encounter flashing red on a fully charged battery you need to call kodak 1 800 235 6325 ext 12

You can charged you camera using 5V AC Adaptor or a USB cable taht attached into the computer

I don't know how to solve your problem but, the three lights mean this:
Red LED light indicates the battery is being charged
Green LED light indicates that the battery is fully charged
Amber LED light incidates that the battery power level is low - the battery needs recharge.
Do not recharge you battery over 24 hours.

the battery's are most likely dead, (like the real dead) after many uses of rechargeable battery's they slow stop holding charge at all, make sure when you get a new rechargeable battery you fully charge it once and fully discharge it once this will increase batterys life time

According to the manual, the red light comes on while charging when the battery does not yet have enough charge to sustain a 3-5 minute shave. The green light stays on steady while the razor is charging, and blinks when it is fully charged. If your battery life is short, they might need to be changed.
