Drained battery a little during Brake flush.

During recent brake/ clutch flush. I obviously ran Abs/ servo to flush wheel circuits. Well upon completion I go to start the bike.. A faint click . That's it.Hook up the charger. It charged 4 amps. I
Charge it up. Starts right up. This is the battery I had in it when I bought
It 3+ years ago. So. Question. Did servos running just take enough out
Of it to cause a issue? Or is this battery suspect and needs to be replaced? And if so. What are the recommendations?

More than 3 years on a lead acid battery means you are on borrowed time. However, even with a good battery, I hook my BatteryMINDer up when doing maintenance that requires battery power.

The expensive OEM battery lasted four years. My first Shorai LiFePO4 battery lasted one year. The warranty replacement is doing OK after three years, but I won't get another lithium chemistry battery. Too many disadvantages and the only advantages (small size, light weight) really don't matter on the LT.

I will buy the cheapest lead acid battery WalMart sells and replace it every three years. I think that will be both the most reliable and least expensive option.

Re: Drained battery a little during Brake flush.

I used Battery Mart on-line 2 years ago to buy AGM batteries for a Gold Wing and one for a trail bike. Shipping was fast and they used to carry DEKA Batteries that were made in PA.

My 2007 LT has a Throttlex Battery "AD51913BS" in it, put in by the previous owner. I have never seen this brand before but the terminals are either a little to big or the PO bent the ends of the cable or something. It is a real pain trying to take the cables off I wouldn't use this brand again in an LT. My .02

Re: Drained battery a little during Brake flush.

Yes the servos draw significant power and probably just ran your battery down. Watch it over the next week and see how it does. I have a volt meter on board and after I start and hold the brakes the voltage drops to 11 volts until I rev the engine up and the alternator overcomes the draw.

Re: Drained battery a little during Brake flush.

Not my experience.
I average 10 years out of a battery.

further more, The Shorai battery in my Kawasaki is a few years old now, never charged it. always 14v + come spring.

You really expect us to believe you average 10 years from standard lead acid batteries. That means some have lasted what 12-13 years to offset those that didn't last 10. Or do all of your batteries last exactly 10 years so that the average life is 10 years?

I bet your eyes are brown also.

Re: Drained battery a little during Brake flush.

I'd like to put a VMeter on the LT. But anywhere on the facia panel by the headlight adjuster knob and BC computer is very tight on space.

Re: Drained battery a little during Brake flush.

I ran a Sears Diehard lawn tractor battery in my '85 K100RT for nearly 10 years. Of the two LT's, battery life has only been 3-5 years. Bought the current battery in 2012, so I won't be surprised when it dies. It seems to be fine as I have accidentally left the ignition on twice in the past month and drained it completely. It has charged right back up. I rarely use a charger but ride 50-100 miles several days a week, best way to maintain the battery IMHO.
