Both of my plug-in batteries show green on the recharge indicator but one does not work at all in the drill & the other one runs very weak/low. Is there a limit how many times that you can recharge these battery packs?

Depending on the model number of the charger, the light only shows whilst a bettery is connected.

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)

"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."

I use the Ryobi Li-Ion tools the L-I batteries will cut off when they get to a low charge level this is to protect the batteries Li-Ion batteries life span is shortened when fullt discharged so when the tool suddenly stops put the battery on charge,also if the battery has a charge indicator light for a more accurite idea of the charge (green is charged,red discharged) hold the test button on then run the tool the light may go from green to red if it does that shows the the charge is about depleted if the light stays green you have a little run time left.

Directions say green light indicates that the battery is fast charging only,it does not indicate at exact point of full charge. I let my batteries charge for 12 hours for the first time charging,found out myself the same way. Try that and you will notice the difference.

Yes. It's kind of like a flashlight when your batteries get low the light get dim, but if you replace the batteries light gets bright again. The drill will get weak as battery get low.

Hi the problem is with the cells in the battery what happens is the cells go bad and then dont hold the charge this then causes the battery to seem full when its actually nearly flat, all you need to do if you want to keep using it is get the battery replaced

replacing the battery with a new one will solve your problem
