Battery lessons needed

[chuck hahn]

Ive been punching in the number listed for the battery in the Service manual for the 73 TX 750 and i keep getting "0 Matches Found". So where a sources for conversions on 70s OEM part numbers?? The OEM number I have in the book is..12N16-3B ( 12V 16AH ). And secondly, whats the cheapest places you guys use for batteries???

EDIT...I should add that I am just looking for a standard wet cell unit.

The cheapest for me has been at Menards. Walmart should be close 'if' they have the size battery you need.

I just bought one from here http://www.rockymountainatvmc.com/ $45 or so shipped. I did have to call because their oem section didn't list one for my bike and the saleman cross referenced one.

Auto Zone, Advance Auto, O'Reilly's, Checkers, Schucks, Wal-Mart, Sears, pick one, they are all about the same.

For an odd duck like that you may have to just measure your battery box and try to match the dimensions with the rating (~16AH).

Ive noticed to quite a price range between lead acid and say the lithium ion stuff.. if you went upgrade from regular lead acid, then what would you go with. I dont want to be spending 150.00 for a battery thats not any better in terms of longevity than by just staying led acid..follow me ehere??

... and .... that the terminals are on the same side. Most batterys have negitive on left, but some have it on right.

Chuck,
If you concider an online supplier, check to see if it does or does not have the acid with it.

I dont know much about batteries or what "questions" to ask.. So i guess what i need is pros and cons of all this new tecno stuff out these days. I mean if, say a lead acid averages 3 years for example and costs 60.00 and say a lithium one lasts 8 yers and cost 100. Whats the best deal for the best usable life...that kinda stuff is what im wondering about.

Chuck,

The important things are dimensions, cold cranking amps (CCA) and the posts. If you have the dead battery, take it in and compare it to what's on the shelf.

If you have Batteries Plus or similar, that's a good place to go, they have all the charts

Lead acid - $35=50
AGM - $60-75
LI-$150-250

The AGM is your best deal, $/year

Big T...I believe the battery that i took out of the box was the original OEM battery.. I think it says something like Yuasha on it. Im going over tommorow and will fetch it to take a pic or two and start asking local places for some figures.

My vote is for AGM. Comes fully charged, can't leak like a lead/acid battery, price is reasonable considering battery life ( >5 years). Lithium Ion batteries are nice, but pricey. I would only consider if weight were an issue, which it is not for your bike.
I purchased a MotoBatt off eBay and I could not be more pleased.

I agree with K-K on the AGM choice. By the way, that is a construction style, not a brand name, it stands for Absorbed Glass Mat, and has to do with the fiberglass mats that are between the lead plates in the battery to keep them from touching each other and shorting out. Very thin glass mats allow the lead plates to get closer together, so you can fit more lead in there, giving you higher craniking output with the same size battery.

Not so sure that lithium would be a good choice. They really require a different charging curve, which takes electronic circuitry to do properly. Our older bikes are not equipped properly to do that. Yeah, some of the bobber and cafe guys will put them in, but that doesn't mean they will be charged properly.

I got one of those Gell type batteries in my 1100 and an ordinary acid wet cell in my 1000. Problem is with the Gell is my charger won't charge it, so it says in the booklet, said it would do due harm to the battery, so I have to ride enough to keep the battery up. When it goes it's back to the wet cell, or go buy another charger that is capable of charging up the Gell.

[Steve]

$20 at Wal-Mart will get you a Schumacher Battery Maintainer that will keep your AGM (it's not "gel") battery working well.

It's about the cheapest one I have found that will do the job and do it well.

Here you go, Chuck. This is a link to a MotoBatt product:

I'm a little hesitant to buy warrantable products on EBay in case things go wrong, but it's an option. The price doesn't seem too bad for the product.
