The scooter was in storage for some time--I'm sure the batteries completely ran down. Do you know if a trickle charger can be used to bring them back?


Hello Lara, go ahead and try a trickle charger. iIf your batteries are more than 3 years old, they may not recharge even with a trickle charger.

Where can I get a new set of rechargable batteries for my cobra microtalk cxt275


The Cobra CXT275 radios can operate on any type of battery (Alkaline, Ni-Cad, NiHM). Each radio uses 4 AAA batteries. Only special rechargeable batteries can be recharged in the actual radio (see below)
If I remember correctly, they come from the factory with NiHM batteries rated at 300mAH. "mAH" stands for milli-Amphere-Hour and it represents the storage capacity of the battery. (The larger the mAH, the longer run time of the battery)

You have 2 options: A or B
Option A) Buy a set of Nickel-Metal Hydride AAA rechargeable batteries and a external battery charger. When the batteries die, pop them out of the radio, and charge them in the external charger. When they are recharged, pop them back in the radio.
Option B) If you want the ability to charge the batteries in the radio, using the "drop-in charger" then you will need modify the batteries so they can charge in the radio.
Follow these steps: You must be somewhat electrically inclined to do this...Note: By doing this you are going to void the warranty of the radio and new batteries that you just purchased.
1) Buy a set of Nickel-Metal Hydride AAA rechargeable batteries. You can probably find some rated at 600 mAH (this will extend the run time)
2) Looking at the back of the radio with the cover removed, there are 4 slots for batteries.
3) Looking at the battery slot on the far right, you should notice 2 contacts for the negative contact. The one on the bottom, is the contact for the radio to receive power from the battery. The one on the side (about 1/8" inch up from the bottom contact), is the contact for the charger to recharge the battery.
4) You will need to modify 1 battery for each radio. Somehow you need to bridge the bottom contact with the side recharge contact.
5) (look at the negative end of the cobra factory batteries and this should help you realize what you need to do) depending on the manufacturer of the new rechargeable batteries, you may be able to use an X-acto knife and remove 1/4" of the plastic wrapper from the bottom of the battery on the negative end. This should reveal the metal shell of the battery that can mate with the radio's side recharge contact.
If it does not, you need to find another way to have it mate with the bottom contact. You might be able to use some Aluminium Foil to bridge the bottom contact with the side recharge contact. Be sure the Aluminium Foil does not touch the positive contact of the battery to the left! You could have an electrical short!
6) Insert the Modified Battery into the right slot.
7) Insert the other 3 new batteries into the other slots. These do not have to be modified. Only the right most battery needs to be modified.
8) Drop the radio in the charger for the batteries to charge. The red LED on the charge base should come on. If it does not, then the side recharge contact is not making a good connection with the negative battery terminal.
9) If the red LED comes on, then the modification works. Let the batteries charge for 24 hours for their first initial charge.
10) When the batteries die after radio use, then charge them for about 12 - 16 hours in the drop-in charger. Do not let the radios sit in the charger for long periods of time. That can destroy the batteries. Take the radios out of the charger when the allotted time has passed.
11) If you hardly ever use your radios you will want to drop them in the charger for about 8 hours every 3 months. This will keep the batteries fresh without damaging them.
I hope this helps, Thomas (Electrical Engineer)

I have an Energizer Model CHDC7 battery charger for AA/AAA batteries. I'm not sure how to use it. Specifically, when batteries are inserted and plugged in, it displays flashing green lights over all...


Nickel-Metal Hydride (NiMH) batteries are usually charged in pairs in consumer chargers. The CHDC7 can charge two or four batteries at a time. Their position in the charger is important (see the link at the end of this note). Each battery has a separate pair of green LEDs. There are no other LEDs on this charger. The LEDs light up to show the state of charge. Flashing means it is charging. Solid means it has reached that level of charge (ie, 1 LED = half charged, 2 LEDs = fully charged). The batteries will get warm but not uncomfortably so. After some practice you will be able to tell if they are getting too hot (which may signal a worn-out battery which should then be replaced). Like all rechargeable batteries, NiMH batteries have a finite life (measured in number of times they've been discharged and recharged). IMHO, they should also be used and charged in matched pairs. I mark them when I take them out of the box and keep them paired in use and in charging for maximum life. Yes, the devices that use 3 batteries are a pain to deal with. LOL. All details can be found on this Energiser data sheet: http://data.energizer.com/PDFs/chdc7_instructions_english.pdf

P.S. The CHDC7 remains open for charging. Closing it for storage is optional but minimizes the space it takes up.

My fone dead put charger in does nothing dead dead dead


Nokia phones are notorious for slow response time when recharging from a completely dead battery.

Remove battery.
Make sure there is good contact between all of the contact points.
Replace battery.
plug in charger.
wait for at least 5 min.
If recharge symbol does not appear in window, then one of these things has occurred:
1. Phone has internal damage or water damage. no way to fix without nokia service.
2. Battery is dead. Try a new battery
3. Charger is bad. Try a new/different car charger or home charger.
These chargers are very inexpensive on Craigs List, try to solve it before throwing away the phone. Good luck,
A former Nokia employee.

I have an Olympus C-765 for 5 years. Lately, the battery does not charge and in fact I cannot use the camera. How to know if the problem is with the battery or with the charger


1. Do not use ordinary batteries. Use rechargeable NiMH.

2. Measure battery voltage using tester or volt meter. 1.2 v for rechargeables.

3. Try measuring charger output.

Is the battery in my Nuvi 350 rechargeable, and if so, how do I do it and how long does it take


Yes, the battery is rechargeable and can be charged (3) ways:

1. Car charger.
2. Wall charger.
3. USB cable (less advisable due to current limits of USB port).

A new Nuvi is shipped with all (3) charger/cables. Overnight charginging is ideal.

Jabra BT350 Bluetooth Headset


This is what I did:
1. open the headset by following these steps:
http://www.instructables.com/id/Jabra-BT-350-Disassembly-and-Repair/
2. measure the voltage of the battery. If it is too low, the internal charger circuit may not like it. Mine was 2.6v.
3. Charge the battery "manually" by connecting to 3 serially connected rechargeable batteries (final voltage should be around 3.7v). Three NiMH AA batteries are fine.
4. Reassemble and hope your headset is back to business.
