I charged my KX-TGA652, it keeps saying use rechargeable battery. Does not seem to hold charge


It does take rechargeable batteries. Remove the back and change batteries for Ni-cad or similar rechargeable batteries. Trying to recharge normal batteries is dangerous. Any rechargeable make of battery will normally work and they recharge when phone is in cradle

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

Can you use 18v lithium battery in old 18v drill


Yes you can. On tools, 18 volts is 18 volts. Tools don't 'know' how the power is being created, either by Ni-Cad or Li-Ion means. Chargers are totally different. Most Li-Ion chargers can charge older Ni-Cad and some Ni-MH batteries but older Ni-Cad chargers will charge Li-Ion battery untill they overheat and sometimes start on fire because older chargers can't detect when the Li-Ion batteries are full.

I just bought the Lithium - ion batteries for replacement for my 18.0 volt ni-cad battery. when I put it (ion battery) in the charger (ni-cad charger) no lights come on. what's up?


Lithium Ion batteries don't charge the same way ni-cads or ni-mh do. You need a lithium ion specific charger to charge them. (Some chargers do multiple types.)

Hi there, I have a MiproACT-707 TM, which i use while teaching aerobics classes. After working perfectly for about 10-15 minutes - it stops working completely. This happens with brand new fully charged...


Hi, I would first ask if you are using a Ni-cad rechargeable battery system, these are not optimum performers for such a high drain microphone as probably the one you're using. Especially if the mic. takes a single 9 volt battery ( the average ni-cad 9 volt is about 200 milliamp hours, not a lot. If so-try switching to nickel metal hydride ( Ni-Mh ) these are better for high drain devices and do not develope a " MEMORY " effect ( which will cause rather sudden power loss ) memory effect can happen to almost brand new batteries as well, all it take to incur this is to charge a Ni-cad before it is totally dead. good luck, and thanks for choosing FixYa-Prodzilla

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.

I need ni-cad battery specifications for Acoustic Research AW-721 headphones. I bought replacement ni-cads but they don't charge when the headphones are placed on the headphone cradle/charger.


The AR AW721 headphones require 3 AAA NiMH batteries, not Ni-Cad. The original batteries are 1.2 volt, 550 mAh. I replaced mine with Energizer 850 mAh AAA batteries, which work well and actually last longer per charge than the originals.

We have a Firestorm drill and have had conflicting advice on charging the batteries. which is correct flatten the battery right down or charge as soon as it loses power. ?? thankyou Colin.


There are different types of battery, the old ni-cad (nickel cadium) batts lasted longer if you let them run right down before recharging them as they had a 'memory' which meant if you charged them from half life they wouldn't charge as much after a while. The new Ni-mh (nickel metal hydrate) and li-ion (lithium ion) batterys don't suffer from this problem so you can recharge them whenever you fancy. The li-on batts don't tend to run compleetely out of charge as when tehy have lost a certain amount of power they just stop anyway. If your batt has lost some life it is possible to get it re-formatted' in some cases by having it put on a battery discharge tester. This is a bit of kit that fully discharges a battery from full in a short space of time and measures it's capacity by timing it. Because it completely discharges and recharges teh batt acouple of times quickly it can someetimes reinvigourate the batt.
