Battery drains battery keeps draining down bought new battery same problem needs recharge in 4 days power safe works on -off switch works

Modern cars have parasitic drain from all the computerized control. It requires systematic approach to identify the myriad of potential causes. Eliminate any aftermarket devices which includes any plug in power supplies. After market radios, security, and remote starters are notorious parasitic drains.

How fast does the battery drain to a level that it no longer cranks? You need to verify it's recharging properly. Most auto parts stores do this diagnostic no fee.

If overnight then it's a gross drain. Over a couple days then it's a moderate load. If several weeks, it may be normal.

There is probably a small drain on the battery - perhaps the luggage compartment light isn't switching off.

The car alternator isn't really capable of recharging a battery due to it's high internal impedance. It is better to recharge it independently.

There may be a "fusible link" hanging off the side of the battery that might be blown. That could explain the "no power" problem. Once that's fixed, you can begin to find where the heavy drain is.

you don't say how long it takes to run down it sounds like you have something that still switched on does it loose power after you have driven somewhere or just overnight

Check alternator voltage output, might be low. obd2 scanner

1)teh batteries are not the right typ use or alkaline or only NIMH
2) if shooting a cold area, keep the batteries warm by placing them in a inner pocket, until you ready to use them
3) battery terminal are diry, wipe them very well, with cloth and ethylic alcohol to 70%
4)the batteries have not been used for over a year.
God bless you

If the battery is getting old (4 to 5 years) it may not be able to hold a charge as well as it did. Have it tested, it may need changing. If an alarm is fitted to the bike it will drain the battery as it will use power even in standby mode.

Either something is draining the power or your alternator is not recharging your battery. Do you have a DC voltmeter? With the engine running check the voltage accross the battery it should be about 14 volts. If it's down around 12.5 volts with engine running the alternator is not working. If you determine the the alternator is working and the battery goes dead, then there is a draw on the system. It could still be the alternator though, there are diodes in the alternator, a diode acts like a one way gate for electricity. With one bad diode the alternator will still work but, when you shut the car off the alternator drains the battery back down. Something is drawing it down, without testing equipment, you'll have to take it to a shop. Something you could try, after the car has been shut off for while, an hour or more, go feel if the alternator is warm or hot, if so it's drawing the battery down. Disconnect the battery overnight so it doesn't go dead on you.

the camera takes 1.5v to operate it
anything less the camera will shut down
recharge batteries are only 1.4v so at full
recharge it won't last long
The best batteries are litheum that have the right
volts and capacity to keep the camera going.
try turning or the camera stablizer setting...
might save your battery power.

Hello,


I suggest you use rechargeable batteries. They usually drain faster than the alcaline ones anyway.So have 2 sets of rechargeable batteries. Evaluate the number of days a set lasts. Insert the charged batteries before the old ones are thourougly drained.

The life of your batteries in the calculator depends on the usage.

About repairs: I am convinced that it will cost you more to have it fixed than to buy a new HP calculator (HP 49g*'s, HP 50g* 's).

Hope it helps.
