Honda Rebel 250 Battery Replacement

I bought this bike with only 1200 miles on the odometer. Yes, the battery is dead, and so I decided to replace it myself.  Paying $ 79.00  + %10 tax, for the Yuasa YTX7L-BS battery  plus  $80.00 for the activation /  installation just wasn't  "working" for me.  Specially since  I can buy this same battery for  $62.99, with no sales tax  from the and activate and install it myself. About  $100 in savings !!!

By adding a few more items (oil and chain lube) I was able to get free shipping deal as well. I placed  the order Monday afternoon, and everything arrived on Friday the same week.

Here is the battery as it arrived:

Before replacing the old battery, the new one has to be activated and charged. Activation and charging are simple.

Unpack the battery and the acid container. Acid is highly corrosive, so wearing gloves and eye protection when handling it, is a good idea. Once the battery and the acid container are out this is what they look like (plastic acid pack is inside the box).

The black plastic strip with 6 caps, is what will cap the batter once it is filled with acid and charged.

I placed  the battery on a flat surface and removed the sticky foil that covers the 6 cell opening holes

After removing the black plastic strip (6 caps) from the acid pack, I positioned the acid pac's foil covered opening over the battery cell holes nad pressed down. I could see the acid starting to flow in to the battery as the acid pack foil seals were punctured and it sank a bit down.

I left the acid to drip in to the cells until the pack was empty, and then I tapped lightly on the pack's walls to make sure every drop of acid ended up inside the battery cells.

My motorcycle mechanic warned me to let the acid soak in to the battery innards for at least an hour before attempting to charge it. I was told not following this advice can considerably shorten the battery's life-span. So, I let the battery seat for 2 hours (for a good measure), before connecting the motorcycle battery charger to it. 

Two hours after filling the battery, I connected the battery charger, and left it to charge untill the charger light changed to green, indicating it was fully charged.

3 hours later the charger light  turned green and the battery was ready to be installed. First things first,  I capped the cell openings with the plastic strip with 6 caps which was initially placed on the acid pack. I placed each cup on top of the battery cell opening and gradually pressed each cap little by little in to the battery cell openings. The caps are connected and you don't want to drive the first one all the way in while the other caps are hanging outside (don't ask me how I know this).

With battery charged and capped, it was ready to replace the old dead battery.  To gain access to the battery compartment I had to remove the left plastic cover.

The screw threads in behind the panel and is also held in place with a "counter" nut. As I took the Philips  screwdriver to the screw head (leftie loosie), I held the nut on the opposite side with my fingers to stop it from rotating together with the screw.

With the screw and the nut  out (stored in a plastic container next to the bike - so I can find them later), I gave panel a light tug and came off . You can see where the panel's posts enter the rubber grommeted holes once you remove the panel.

To remove the old battery, I had to:

a) Unscrew and remove the negative "-"  and then positive "+" terminals.

b) Remove the rubber belt that hold battery in place.

Then I reinserted the newly activated and charged Yuasa Yuasa YTX7L-BS and reversed the procedure with reconnecting the terminals. I also added the quick connect charger cable, so I can trickle charge the battery when the bike is not in use without removing the side panel.

I inserted the key and turned it in to "ON" position. The green "neutral" light came on and I could see the headlight glowing nice and strong. Choke on, Engine cut off switch "ON", hold the clutch lever and press the starter button. The engine turns once, twice and WROOOM ... !!!!! My little Honda Rebel 250 is running ! I hope you had fun reading my  story, now go and write one of your own.
