How to recharge my dead batt.

hi have you tried other battery? if not, kindly replaced it. if yes, pls bring it to service technician to open it i guest inside board is wet due to rain, they will used hot air blower to dry it. thanks

That means you have to put new batteries in your scanner... or recharge your rechargable batteries but if you use rechargable batteries use your yellow battery cradle for rechargeable batteries and your black cradle for alakline batteries....foe pro 82...

The Batts can be charged externally, then refitted, usually I extend the DC cables so I can work with the batt outside the unit. This is ONLY to be done if you understand the risk and what may happen if you get it wrong.

Batts are always live and can cause fire/explosion/severe burns if shorted!
IF YOU ARE NOT SURE THEN GET SOME EXPERIENCED HELP!

OK so the UPS will not normally recognise a very low batt pack, that is the reason you can not start the test, this test will back of the rectifier so the batt pack takes the load for a short period.

If the batt pack is out of range then this will make the load go off, so the UPS is designed not to allow the test,unless the batt is at the right level.

If you can get the batt pack up close to normal then the unit will recharge it to full.,Wait until it is fully charged before testing.
If this is sucessful the cyle the batt a few times allowing it to reach around low batt warning before recharging. This will assist the batt in recovery. During this process if possible monitor with a test intrument(fluke 123 or 43B will do) the batt pack discharge curve , once the batt pack has dropped to its charge level from float, it should be a smooth decay.
depending on the state of the batts you may be ok, if there are weak ones in the string then you may have to replace all of them depending on the age of the batt pack.

MAKE SURE YOU ARE VERY CAREFUL WITH BATTERIES, THEY ARE VERY DANGEROUS, AND ALWAYS LIVE!

Check you manual for safety procedures, BEFORE working on Batteries.


hope this helps

thanks for using Fixya

if u put 3 bateries on a loop u can charge them on a 24v loop

may be it got stuck try to move it by ur finger cuz mine one opens half some times so move it by finger ..... try it it might work for u ....

You can only recharge ,rechargeable batt. so many times and then they are no good this information is some times on the packing.....

Remove stain from batt. location , spray it WD40 inside batt. compartment then use NiMH batt. enelop white color

Your battery is probably dead.This has worked before,take your batt out and put it in the freezer for 4 hrs then recharge it. Hope this helps.The worst is you need to buy another batt.
Let me know.

Same unit, same problem. I found that when the internal batt is dead current draw on the USB port is not enough to recharge. I have a USB car adaptor (it is for my kids PSP ) and use it to recharge the batt when it goes completly dead. I keep a eye on the remaining batt life and charge it via the computer USB before it gets to low

if you did keep the lappy on the charger all the time with the batt still pluged in it will wear the batt down...Yes even if you never ran off the batt...they lose power and recharge even when not being run off of...check the connections though and if you can see any probs (dirt,disscoloration anything) then it could be there. If now try finding a batt store that deals with batts they norm can test and fix em if its only a cell or so that has gone bad other than that run it down till its dead and recharge it to the max and see..
