Batteries die quickly - unit gets hot

My Rhino 120 dies after about 1/2 hour, fully drains the batteries(I can watch the batteries indicator drain before my eyes). The unit also warms up and the display and surrounding areas get pretty warm. Never in or near water, no impact damage. What is the problem?

    I have a rino 120 that I have had for about two years and it gets very hot after about 5 minutes with new batteries in it. I have tried both alkaline and rechargegable batteries and they both do the same thing - gets very hot. I have also plugged it into my cigarette lighter adapter - no batteries and it still gets hot. I put in new batteries and left the unit OFF and it still got hot. I own 4 of these and only have the problem with the one unit. I have tried to update the os, but it doesn't help either. Does anyone have a solution other than sending it back to Garmin?

    I have the same problems with my 120. I have a 130 and it works fine. I saw another unit on craigslist that listed the same problems. Has garmin done a recall?

You may have a bad or shorted battery pack. You might try replacing it to see if the problem goes away. It would be normal, while charging for a battery to get warm. But not hot. Rechargeable batteries have a life expectancy of 18-24 months.

    Check your battery contacts to see if there is a break in the solder which connects them to the board. Something is shorted, if it is not the contacts, it is in the component board itself. This could be from a variety of causes, including pressure against the unit, such as being simply sat on, causing a hairline crack in the board. If this does not reveal the problem, contact Garmin.

How do I stop the battery from draining after only a few hours.

try letting the battery completely die and recharge it. Do this 2 or 3 times. Sometimes "topping up" a partially charged battery puts a memory into the battery and it wont allow you to do full charge.. I let my Nokia get to its last legs before replacing the battery with a spare and then fully charge the other one. Both batteries are now at least 6 years old.. Yes , its an old phone...

Why are the batteries dying so quickly in my Kodak 12MP?

It depends, if you are using regular Alkaline batteries, those are known to go dead really fast. Better if you try some rechargeable batteries with a rating of at least 2100mAh, anything smaller than that will drain just as quick as Alkalines.

What is the life of my satellite l30-101 battery off the ac charger

Toshiba's line of Satellite PC laptops offers a variety of screen s that are customizable when ordered online. The laptops offer built-in webcams and backlit keyboards. Most Toshiba Satellite laptops use six-cell lithium-ion batteries that can last up to six hours. To reach that six-hour mark, you can use several tricks to maximize your battery's capacity.

Charge your battery completely before its first use. Check your user manual for the exact charging time required, which is typically at least 12 hours. Discharge your battery completely every two months. Allow it to drain fully before recharging it. Recharge it completely, for at least 12 hours before using it again. Remove CDs and DVDs from your laptop's drive when not in use. These drives spin when loaded, which can drain your battery unnecessarily. Set your laptop to hibernate mode when you need to take a break. This conserves more power than standby. Store your laptop battery in a cool place. Never let the battery sit in direct sunlight or leave it in your car on a hot day. For even longer battery life, remove the battery from the laptop which can get hot while in use when you are plugged in. Turn off your Wi-Fi connection when not in use. Constantly searching for a Wi-Fi connection can drain your battery faster. Work in only one program at a time. The more programs you have open, the faster your battery will drain. Unplug any USB devices, especially those that charge when plugged in, such as your cellphone. These will drain your battery quickly. Dim your Satellite's screen to conserve battery. Hold down your "Fn" key and tap "F6" several times to dim the screen. The "F6" key should show an open circle with small lines radiating out, to symbolize a dim display.

I have been having this problem with my Olympus mju1040 for quite sometime. Everytime i tried to charge the battery when the battery low signal is blinking or when the screen blackout, it will be fully...

Try charging it for an hour even if it is indicating that it is already full in 10 minutes. If the battery still gets drained after a few shots, then you should change your charger.

An older unit. No service available from Garmin as it is obsolete. The 120's have a lot of problems. Poor battery life. Poor reboot and constant dying after on. I would find another unit.

How long to charge cordless battery for Oster Power Pro Ultra

Usually it is recommended that you leave it plugged in to charge a minimum of 12 hours before you even use it. Then, once you unplug it to use it, keep it completely unplugged and use it until it dies completely and shuts itself off. Then, and ONLY then, plug it back in and charge it again for a minimum of 8 to 12 hours and do not use it while it is charging! Once you've passed the 8-12 hours, you can unplug it again and start using it again. After you do that, you should be able to use it for a few days before it dies and you will have given the battery a "memory". After that, you don't really need to have it plugged in more than a few hours to fully charge after being drained. It's always best to let the batteries fully drain and shut off before plugging back in to preserve it's life.

Overheat/battery drain

Hello dogwillhunt,

It is normal for a two-way radio to generate some heat, especially during extended periods of long talk time. Consumer two-way radios tend to be much more susceptible to this because they tend to be constructed out of materials that do not dissipate heat very efficiently, such as polycarbonate and plastic. Periods of heavy transmit times also use additional power, causing the radio’s batteries to run down more quickly and require replacement or recharge. Use of the display backlight feature can generate additional heat and run the unit out of battery power even more quickly.

If the radio is heating up excessively and burning through batteries (pardon the pun) in situations where you are not using the LCD backlight excessively or transmitting for long periods of time, this may be indicative of a problem with the unit that would require service, such as a short or defective component. If such is the case, I would recommend contacting the manufacturer.
