2009 accord , Memory saver ? Sign In

I'll probably need a new batt. on the 2009 accord with a 2.4 . Do you know if I'll need a memory saver ? Thanks .

Most vehicles do Doc: This one (many now) the power ports/cig lighters are off with key off. You can use or make a rig AYOR that powers the cables (don't let them touch ANYTHING till back on a real battery - using a 9v (like for smoke detectors) battery. Also just look for gadgets there's more than I would know of sold all over the place in stock you should own one.


It just saves more than computer memory assorted vehicles are a real PITA to reset everything they have just ordinary stuff now, memory anything, clocks, seats, driver 1+2 and so on never mind certain radio/sound system stuff,

O.K. I charged the batt 2 days ago and it has reservoir caps so I figure it's a goner , but who knows I'll have them check it . I'll see what I can wire up safely .

Caps? IDK but don't think MA allows them except commercial use? Batteries are dated either plain like B-6 would mean Feb. 2016 for example or in codes you can find when it was made it's embossed in the plastic of them - has to be for at least warranty reasons or more.
It's another IMO at 3-4 years old you are at much higher risk of a surprise the exception is beginning to be the AGM types look and see how costly those are vs regular ones still sealed except for a "gassing" event nobody wants.


I beat on battery a lot here toss early because a meltdown of one is so destructive to so many other things either going weak or a short you really louse things up.


It's costly to keep dumping them also a risk with new so beat on it more, charge it up with a charger/maintainer before you install a new one. If it can't take it right back! Laugh - the battery places don't like me I take a lot back NEW!
Whatever you do it's still worth saving memory in about anything for road use even tons older than this,

The auto store didn't have what I needed the guy at the counter said to swap the battery while the car's running and that he used to do it all the time ., I told him I wan't the old one tested and that I'll be back . What do you think about disconnecting batt terminals while the car's running ? I've seen a guy on U-TOOB do it on a car but from what I gather I"ll say don't .

NEVER EVER disconnect the battery with the car running. The voltage spike can fry every module in the car.

This guy is an idiot to suggest that.

Oh, I know what you are talking about. When you "wanna be" a tech but are not qualified, you work for a parts store and act like you might know what you're talking about.

Re: 2009 accord , Memory saver ? Sign In

Doc, what you could rig and I have just can't suggest it for just anyone. If able to be super careful without fail jump from even 9v battery still with alligator clips (they must stay on small 9v one) to cable ends at the U-bolts for Honda. DO NOT LET THOSE SHORT OUT WHILE CHANGING BATTERY!
If it does at least it's lower force from tiny battery is enough to remember info IF NOTHING GETS TURNED ON OR LEFT ON! No hood lights, doors open or anything for the quick time for the swap.
Duh - there's risk there but such is life CERTAIN DO NOT ALLOW ANYONE TO DISCONNECT BATTIERS WHILE ENGINES ARE RUNNING! OMG that's risky since alternators in anything were in use the first (trivia) was put in a 1959 Chrysler Valiant! So take that! :-) Tom

Re: 2009 accord , Memory saver ? Sign In

Auto zoo has a saver they can hook up while we put the new batt. in , I ordered a saver on line but free shipping snail mail is 2 weeks but at least I'll have one after that . If I rig something up There's the chance it'll come loose and ruin everything and I don't want to take that chance .
I remember the neighbor telling me about the centrifugal force of an AC compressor and he couldn't pronounce centrifugal . I thought that was funny , I didn't listen to him , the freon he suggested I put in would have been lost right back out through the leak .

Re: 2009 accord , Memory saver ? Sign In

You're probably making way too much out of the memory saver stuff.

So what if you have to reset the clock and the radio stations and drive it half a mile to relearn the idle strategy.

Re: 2009 accord , Memory saver ? Sign In

So True: As Hammer said it will re-set by itself not "radio" or devices that want residual memory. Those just do yourself or just drive tolerating some stalling (maybe) and lousy recovery of expected loads, turning corners, A/C and more. It comes back.


For a customer it's rude IMO to ignore that have stuff on hand so that isn't a factor. The "unaware" customer freaks out sometimes car is all screwed up over just even cleaning a battery up!


If you also need to get inspections for many places you can't or wait "STATE" (where I am) just gets a "not ready" so don't get one. More annoyance.


All this over just being ready so I'm sorry for beating on it, I AM READY so don't think about it much more than that.


Refresh: Just remember the well meaning of friends, "Sammy the stud snapper" neighbor and more don't have a clue AND DON'T LEAVE ENGINES RUNNING.
It's also (if battery is out for any good reason) need time to rust/corrosion proof hardware that holds it in place takes more time use a smaller real 12V battery if it take a day fixing or painting up icky metal, broken hold-down hardware etc.
If folks paid attention all along and kept a vehicle for knowing it would need periodic battery removal replacement it's just nice that it's never a wild hassle again or be ready for another - I am it's routine but ignored to take care of the dang things!
Unreal how easy it is (if keeping vehicles) how much better it is later new they are NOT very well done catch it for first terminal clean up save hours of grief later.


All in all being ready isn't that costly vs the time and aggravation later.


Scary Doc you are 99% more aware than "Joe/Jane" public or the Autozoo type places they even sell all the stuff to make it easy later just takes some brains (I wonder about that out there all the time) to know just that if you do it routinely and they offer that so do major others that still ignore it and tick off customers/friend or yourself!

Re: 2009 accord , Memory saver ? Sign In

Yeah I do look into things too much but I have a haynes manual for the 09 accord and it said you need the codes for the radio after un hooking the radio and about 4 other things that sound like a PITA , And I did want to clean up the batt tray while it was out but the guy putting it in wasn't into that and I don't blame him . After he put it in it didn't crank so he said he tightened the + terminal , another funny thing is the batt. I needed just happened to be sitting on the counter , he said it was new . Only the 3 year batt. was good enough for this vehicle .. Now the spare is getting mounted with TPMS that has to be programmed with the car and that should go off without a hitch . Just gimmee an old dodge or a nova please .

Yeah , I forgot about that radio lock on the Hondas. That can be a real pain in the ass if you don't have the code number.

Re: 2009 accord , Memory saver ? Sign In

My wife's not aware of any security codes but we're not sure , As far a the memory thing I'm more concerned with the thing not even wanting to start or some other such nightmare . The guy installed the batt and said take it for a ride to ensure a good charge , he used some kind of stupid analogy . I don't remember ever buying a new batt and having to " take it for a long ride " . Right now I'm charging the goombah thing in the drive way because it died at the tire shop .. I think it sat on a shelf for who knows how long losing it's charge . I think they owe me $80** for the towing

Re: 2009 accord , Memory saver ? Sign In

Yes, all Hondas have a 4 digit lock code for the radio if power is disconnected. Look in your glove box for it. It's a real pain if you lose it.

Yes, I would dump that battery right into their lap. No battery should be on the shelf for 6 months or more.
If it has a sticker with a letter and a number, that means it has already expired and they recharged it and extended the warranty 6 months.

Re: 2009 accord , Memory saver ? Sign In

Thought I already said they are NOT fully charged NEW, DAY 1 from just filling. There's handling of the things AFTER that by who knows who and on till you get it think it's new so are marked. 6 mo. is way too long from original fill without a real charge up FIRST and before you even put one in test it out of vehicle dump it then not this scene again!


It's life can't be full expectancy now if first crack wasn't starting the car otherwise if nothing wrong with the car's system for charging I'd dump that battery now while you just did it for another new but make sure it's dead or get told it's fine - it isn't. Your call on that I'm a pest they get those back right away before seeing a vehicle, machine or any reason I want one for me or anyone,

Re: 2009 accord , Memory saver ? Sign In

Once I got it home I put a charger on it and the needle jumped and steady after a while it came back down showing a full charge and had 13.3 volts with the multi meter , but it still cranked only a turn or two . I'll look for that code in the box , I have another batt I can try , I'll look for any white tags on the new one if I bring it back and things will have to be reset anyways . If the batt. is good that leaves the starter ? /

Re: 2009 accord , Memory saver ? Sign In

The tag won't necessarily be white. It could be any color. I've seen a lot of yellow or orange. It will be a round dot about 1 inch across with a letter and a number. They are codes for the production date.

The original code is stamped right into the casing. The sticker is added if it is taken off the shelf and recharged and then put back into inventory.

Re: 2009 accord , Memory saver ? Sign In

I took the batt out of the accord and put in a civic batt that I know is good and it still did not crank , the "new" batt did have a white label on it saying 6-20 and 0F04AHZ melted into the upper lip of the caseing . I did a search on that # with no real results . My wife looked into the radio code thing and found our model does not have one for security , After re connecting the batt I turned on the radio and everything was still there . But it still doesn't crank .

Re: 2009 accord , Memory saver ? Sign In

You're going to have to do some testing here. Do you have a digital voltmeter and do you know how to do a voltage drop test?

Re: 2009 accord , Memory saver ? Sign In

you mean get a volt reading on the batt. , engage the starter and look for a drop under 10 V ?

Re: 2009 accord , Memory saver ? Sign In

No, that's not what a voltage drop is.

Say you want to test the battery cable. You attach one of the test leads to the battery end of the cable and the other lead to the starter terminal at the other end of the cable. Set the meter to 12v and crank the engine. Ideally you will see no reading on the meter. If you see 1v or more, then there is too much resistance in that cable.
This test will determine too much resistance in any electrical circuit.

Re: 2009 accord , Memory saver ? Sign In

True as HT just said but Doc if you see under 10v while cranking it does mean it isn't right just not instantly why. Think (my analogy) water pressure thru a hose that's clogged or has a problem then you lose how much pressure and volume both at once only for a short time if not working the pressure should be there is VOLTS just not the volume so they do mess with each other.
Cables - both are only as good as the weakest one or spot from battery and route back to it - EVERYTHING, Tom

Re: 2009 accord , Memory saver ? Sign In

We are looking for a problem point in the supply circuit and the test I explained will pinpoint the problem.

Simply watching the battery voltage drop doesn't tell you anything about what the problem may be.
