Time for new battery??

[jodebg]

I have a 2004 B7800 with an origianl battery and have 3 questions:

-When starting, it cranks fairly slow. Is this because of age and will a new battery crank faster? Winter is also on it's way/cold starts.

-What is the best battery to use?

Origianl battery is a......Yuasa #55B24L (S) MF

-Worth getting a higher cranking amps battery?

If it was me and I got 10 years out of the battery I would be looking for exactly the same one if it's only starting to crank slow now and no problems in the past.

Just found out that this Yuasa model number is no longer available.

That's good service from a battery, but if it's cranking slow now it will be a problem when the temperature drops. I usually use the largest battery that will fit when replacing. My personal preference is Optima red or yellow tops.
For exact fitment, read the BCI group size off the old battery (24 ?) and pick your poison in brands of that size.

I usually just measure the available space for the battery. Then go to Costco or Sam's Club, (or even Walmart) and buy the largest battery that will fit and also has the highest CCA. Costco has the best replacement warranty in my experience.

Be extra careful that the + and - battery posts are in the correct position. You may have to buy longer cables if they are not.

I'd say that with 10 years of service you made out like a bandit on the OEM battery. Expect 3 to 5 years out of a replacement.

Oh, and clean up the cables where they attach to the battery and where the ground attaches to the frame. If you need a new - cable, buy one long enough to attach the ground to a bolt on the engine. It is a much more secure and functional option.

Thanks.

Any advise on the proper procedure to switch over to the new battery?
Which cable to remove first, etc.?

Always remove the negative first then positive.....

then hook up positive first - then negative with new battery.

If you ever did it the other way and the wrench slipped, YOU will understand WHY it is done in that order!

Buying the most cranking amps for whatever sisze battery you choose can at tumes be a mistake. 24 series 1000 amps is not a good choice. A 650 or 850 max in the 24 series is plenty.

Higher amperage means more plates,closer together and thinner weaker plates.
Weaker plates means wont stand up to vibration.
More plates means sulphation will affect battery much sooner
And more plates will short if plates move/warp.

Please take a few minutes to read about batteries and charging systems. There is a reason you don't put 1000 CCA battery on a system designed for 550 etc. CCA is the amps it will deliver for 30 seconds without dropping below 7.5v ,measured at 0 degrees. CCA is not the only number you need. RC reserve capacity ,how many minutes a fully charged battery will discharge 25 amps until the battery drops below 10.5 v is measured at 80 degrees. Hmmmm which one sounds like the more usable rating? If you use your equipment in winter a lot or spring summer...
