Question about 2005 Volvo XC70

1 Answer

I use a gell cell battery to run a resmed device when I go tent camping. I would like to be able to recharge it from my vehicle on a day trip while camping. I want to give it piority in the charging circuit as my vehicle battery would be able to handle several motor starts and I would need to charge the gell cell as much as possible with limited driving. I thought a switch arrangment may work that would change from the main battery for starting to the gell cell during driving to recharge it. The gell cell is not normally in the vehicle. I would appreciate any suggestions and circuits. \r\nRegards, Kerry

Work on the assumption that a battery needs 15 mins of engine running to fully recharge after one start,so connecting a gell cell battery to the cigar lighter would work perfectly well,especially if the cell was down on charge.

Fully charged battery discharged after trip. Alternator output 14.4 volts, AC out 13.8 volts, Recharged from AC for trip home,dead again at home.


Did you check voltage at battery while running? Or at alternator. Watch voltage at battery at idle, see if there is a drop over a period of time. Should be 13.5-14 volts. It may be as easy as replacing the battery, not just recharging it. Also check terminals to make sure voltage is making it back to the battery.

I have a 2013 Chevy Tahoe with an unexplained battery drain, what could it be? help please


You could have a parasitic drain. Something that is left on in the car and drains the battery. It could also be a corroded terminal on the battery where the alternator is not getting power to charge the battery . Clean the post and the connector of all deposits and install those felt washers under the terminals to impede further corrosion.

2006 freightliner sprinter 2500 with MB diesel; Is there a "jump box" strong enough to start this in the boondocks (no AC power)?


many operators now carry a separate ac unit isolated from the cabin so as to provide ac when the vehicle engine is stopped ( camping/resting). These units are powered by a petrol motor that runs a alternator to run the ac compressor and there are tapping plugs in the panel to charge batteries of the truck.. Because of the size of the batteries needed to jump , I would be investigating the possibility of obtaining one of these units and mounting it under the chassis at the rear area of the 5th wheel pin

Humming after engine shuts off


I'm no Honda expert so I'm not sure if an 02 has a "key off" evap system. If it does that may be what you're hearing. A lot of newer cars will run evap tests while the vehicle is off. It basically pulls vacuum on the fuel tank with an electric motor to test the integrity of the evaporative emissions system and opens / closes vacuum switching valves.

I have a 1996 palomino tent trailer. I came with two older 12 volt batteries and has two battery mount brackets. Is it supposed to take 12 volts or 6 volts. Also do I need both batteries to run...


It depends.
On some models, one battery handles the fridge and heavy loads, while the second battery is for lights. On models that came with one battery, owners have installed a second for longer camping trips. And some owners have switched from one 12vt to two 6vt golf cart batteries for longer power.

BATTERY PROBLEM


Ultimate solution is change the battery... because the capacity of battery cells is poor.. this could be the reason if battery is old...
Still u can take a chance by completely removing the battery fluid and replacing it new battery fluid... but keep in mind that, after doing so, u'll need to charge the battery fully before using it in car...
This kind of battery problem is common in all diesel cars, the reason I think is, Diesel engine need heavy torque to start that draws heavy current from battery.. so if you are facing starting trouble for the vehicle, then battery is surely going to discharge frequently...
Still try the solution mentioned above and still the problem persists, then replace the battery with new one.
((I am considering that the battery you are having is 3-4 years old...))

I have a 2003 f350 6.o diesel and i have change the batterys 3 times in 2 years ,it starts and runs great but some time it the batterys drain and won't start i have it jump and it will run for 3-7...


How many accessories do you have plugged into the power ports? Do you have a lot of stereo equipment in the vehicle? Do you only make short trips with the vehicle? Too much load on the system from accessories (Cell phones, computers, GPS receivers, stereo equipment etc.) will cause batteries to drain. An alternator will provide enough power to run all of the stock electrical load and maintain a charge on the batteries. However, if the electrical load is greater than the alternators output, power is drawn from the batteries as well. Combine that with constant short trips and the batteries will never have a chance to be recharged.

2005 Town & Country Van dead battery after short trips


Possible dead cell in battery, most likely a fault in the charging system. First, Jump Vehicle to get started then remove the Negative cable. If the vehicle dies when you take the jumper cables away or when you disconnect the negative cable your alternator or charging system is faulty. If the vehicle runs without battery connected you have a bad cell in your battery, replace the battery.

I suspect a weak battery, but how do I know it's not a bad ALT?


when your car is running disconnect the positive cord from the battery. if the car stays on, than it is your alternator, if not its your battery. also if the car stays on, the head lights go dim if the alternator is malfunctioning
