Hi, i have a 18v rechargeable hand held vac (pirana brand). It wont hold charge or wont even charge. What can i do to revive and/or where can i get a replacement battery? Thanks

Once the green light goes off, it's done charging. Since it was first charge I know they say to charge it 8? hours (or 4? don't recall right offhand) but it does come charged (that's part of how they make the batteries). What you do want to do is remember not to always recharge it when your done using it. Use it till the battery goes flat, then recharge it; it will give you a longer battery life that way.

Mostly likely it needs a new power pack, but you could try cleaning off the contacts first. Use a pencil eraser and clean the metal power contact on the charging unit and the vacuum. Then charge it over night. If that doesn't help, charge the power pack.

Hello! If you are experiencing a short run time your battery may need to be reset. Try completely depleting the battery. Run the vacuum until it shuts off. Then re-charge for a full 24 hours. The indicator light will come on to indicate the unit is charging. If there is no indicator light on the charger, the charger may need to be replaced. Below is a link where you may go to purchase the charger if needed. Hope this helps!

No, the P110, 18V NiCad battery charger, will not charge a 18V lithium ion battery. You need one of the dual-chemistry chargers. If you have the Ryobi ONE+ batteries, you can get the P117 charger ($30) or a charger with an extra battery (P126) from a store like Home Depot. A 6 battery charger and a 12V in-car charger are also available.

I wish that I had better news for you.

(who has the Ryobi 12V drill and charger, a few of the 4V tools, and a number of the ONE+ 18V devices and chargers. The single chemistry battery charger is not used much any more.)

Rechargeable batteries do have a lifespan, they won't recharge forever. If you have fully discharged the batteries then fully recharged them and they still don't have full power or they only last a couple minutes then they are done. If they won't charge or the charger shows them as defective, the only fix is to replace them.

I have just had a similar issue I left the drill unused for a period and when i placed it in the charger the charger showed the battery as charged after about 15 secondseconds.

Following a internet search i found a site that suggested for a imlar problem with a camera jump starting the low battery with a 9 v battery. I had a spare from the drill which was fully charged so placed a contact from + to + and - to - and held for about 2 mins. I then placed the battery back in the charger and it started charging. Running the battery down as we speak to recharge again well worth a try. If you dont have a spare maybe the 9 v would work

Hi Fred,

I have several 18v tool sets and for the most part I'm quite satisfied with their performance. I currently use Bosch and Ryobi.

When used with the drill, a battery can last me the whole day. On the other hand, the sawzall will eat them up pretty quick.

The thing I've found common to all brands is that it is absolutely crucial to make sure the batteries are fully charged before they get used for the first time. That first full charge seems to set the bar for subsequent charges for the rest of the batteries life.

I too, have tried the discharge/recharge thing. No help. I can only suggest a new battery and letting get all it can take from the charger the first time out of the box.

Since I've been doing that, I rarely even think to bring my charger to job sites, there's that much of a difference in performance.

Hope this helps you out.

Best regards,
Mike
