It has to be shook each time i use it, also can the battiers stay on charge when not in use?


If you have a machine with a li-ion battery it MUST me placed as soon as it stopped on the charger and leaf them on the charger and as soon as they get slowing down the rpm of the machine change the battery it has no memory effect or capacity problem Everything opposite to compare with nickel cadmium batteries ,and that because of the old Makita machines with only have 2 battery connectors are now for 60% modified with a 3 (star)contact battery holder by Makita if it was in warranty time by Makita, the switch and contact plate are modified because of the deep discharge protection of makita because it new (star) li-ion batterys have been allways by every brand on protected against discharge with a similar or comparable protection with a small circuit with a refference power on it , a li ion battery can be boosted with a special cadex charger that will bring back the referrenced power so the charger will if boosted working again on the battery . but if your machine shooks has to do with a contact or soldering problem om the switch possibly or to short carbon brushes but not by the battery .

How to CHARGE CORDLESS DRILL


First, you should know your battery is a Ni-CD / NI-Mh or Li-ion battery. If it is a Ni-CD / NI-Mh battery, please fully discharged and fully charged it to prevent "Memory effect".

If it is a Li-ion battery, please charge it before you use it.

Please keep in mind that, please fully charge a battery when you store it. And, charge it again every two months.

If your old battery is dead, you can replace it with a new one. Ryobi Power Tool Battery

Low battery on a tk3202 two way radio


Hi Patrick,

Are you using rechargeable Ni-Cad batteries?

If so, buy Li-ion Batteries, Ni-cads have a memory and will recharge from last charge only, rather than fully charge.

Lithium Ion Li-ion batteries don't have memory issues, and therefore will recharge fully.

These are available as rechargeable types so, look for the rechargeable types.

I hope this has been helpful.

Best regards,
Peter

Dell Inspiron 6000 (approx 4 years old) has an issue with the power cord internal connection? Battery and Power cord/adapter are fine. Computer constantly switches from battery to AC when powered on. ...


The input jack that is soldered to the motherboard (where the AC jack plugs in) probably has a cold solder joint. Thus the laptop switches from battery to AC power. You can try to have the solder joints
re-soldered.

How many hours we should charge the battery fist time Nokia-2700


There are basically 3 types of chemicals currently being used for cell phone and laptop batteries. Ni-cad, Ni-mh and Li-ion. There is a fourth makineg its way in Li-ion polymer. A couple things are consistent for all types of batteries no matter what chemical is inside. You must initially give the battery a 12-14 hour charge on the home charger. (Don't use a cigarette adapter for the first charge. This conditions the battery and don't take it off the charger that first time even if the charging indicator says it's full after 3 hours. Also the manufacturer's also state to run it thru 3 charge cycles. What that mean's is that you fully charge and fully drain 3 times. 1 full charge + 1 full drain = 1 charge cycle. Here's where the way you charge the battery starts to differ.

Ni-cad: Mostly only on older devices, has a "memory" effect, should be drained before a full charge is put on it, should be removed after overnight charge or can be overcharged and burnt out.

Ni-mh: Still used for some devices, has slight memory effect but not enough to have to fully drain before the recharge, should not be consistently left on charger after full charge that can eventually burn out battery and shorten usage time.

Li-ion and Li-ion polymer: Used on a lot of newer devices, has no "memory" effect, should be recharged as often as possible, actually likes to be charged and draining it regularly can cause the usage time to be shortened, can NEVER be overcharged so whenever you're near a charger put it on there. Besides those benefits a li-ion battery is lighter and smaller but the chemical can hold more charge than Ni-cad and Ni-mh.

So the one reply to your question said to error on the side of draining the li-ion batteries. This is incorrect information. You want to charge the battery before it gets below a 20% charge. Also batteries will not go bad from accidentally doing the incorrect charging procedure here and there but normally follow the correct procedure. One last note try to use the home charger more often than the cigarette lighter charger for best long term results. Cigarette lighter chargers do not give a full charge (about 95%) which in the long run can damage any type of battery listed.
