My vantage pro battery that I had rebuilt last year has a problem. When I put it the charging station the red and green led,s just blink back and forth. Does this mean that the battery is bad?

Yes. When the charger does the railroad crossing alternating lights it indicates there is a problem with the battery. If it was extremely dead, sometimes you can get it to charge by trying it several times. If it wasn't that dead, there is a problem with it.

I understand. Both my Modis and Vantage Pro batteries are getting tired. Especially my Modis battery. I'm not eager to replace them, but they are both pretty old, so I've got no gripes. Funny thing is, when my Modis battery is bad it only runs the tool for a few minutes, if it all. When my VP battery is getting old it still works for about a half hour or so. It'll be totally dead before too long.

Sometimes, and not always, rechargeable batteries can be brought back to some kind of service life buy cycling them through 3 or 4 DEEP CYCLE discharges and recharges.
Charge them up as much as they'll take, and leave them for 6 or 12 hours still charging. If the voltage is up full there is usually very little current so therefore there isn't any heat.
Hooking a light bulb across them to bring them down again till the bulb is dim (but not completely out) and then charging them up to full charge again, leaving them on for another 6 or 12 hours (again low current flow at this point) and then cycling them down again with the light bulb and recharging them a third time, to full charge, and leaving them for another 6 to 12 hours to give them a true full charge and it might last another 6 months or year.
It takes some effort to cycle them but sometimes you don't have to purchase another battery right away.

Here's a tip that an old timer told me about.... Drain it completely and throw in the freezer for a day. Then let it thaw out for a day and charge it... Apparently it "removes" the memory effect. Don't know about that last part, but it does give you a little more life, worked on some 9.6V Makita batteries."If you aim for nothing, you'll hit it every time!"

Thanks for the tip.Comment

You may find it doesn't hold a charge or last very long.
I would suggest you give it a charge, cycle it down and charge it up again.
Good luckComment

It worked a treat.
Awesome tip.

Hi....as per my knowledge rechargeable batteries can be brought back to some kind of service life buy cycling them through 3 or 4 DEEP CYCLE discharges and recharges.Charge them up as much as they'll take, and leave them for 6 or 12 hours still charging. If the voltage is up full there is usually very little current so therefore there isn't any heat. Also hooking a light bulb across them to bring them down again till the bulb is dim and then charging them up to full charge again, leaving them on for another 6 or 12 hours and then cycling them down again with the light bulb and recharging them a third time, to full charge, and leaving them for another 6 to 12 hours to give them a true full charge and it might last another 6 months or year.

Hi...i am a new user here. I will suggest drain it completely and throw in the freezer for a day. Then let it thaw out for a day and charge it. Apparently it removes"the memory effect. Don't know about that last part, but it does give you a little more life, worked on some 9.6V Makita batteries.
