The Amazing Ten-Year Motorcycle Battery
I replaced my motorcycle battery last week. It stopped holding a charge sometime this winter.
The amazing thing about this is that the battery was manufactured in 1997. That's right - ten years ago. It was the OEM YUASA YTX12-BS battery that was in the bike when I bought my Honda CBR1100XX new in 1998.
Complicating the situation: the UNGO motorcycle alarm that I had installed when I bought the motorcycle. During periods where the motorcycle was left unused, it could drain the battery fairly quickly, due to the standby current draw.
Extending Battery Life
How did I manage to squeeze ten years of reliable service out of a lowly OEM battery? Simple: keep it clean, keep it charged! I've alternated between the classic Battery Tender Battery Tender Plus 12-Volt 1.25 AMP Battery Charger
and, more recently, the modern CTEK MULTI US 3300 Battery Charger For 12-volt lead-acid batteries.
In all, I'm amazed (and pleasantly surprised) at the extended service life I experienced.
R.I.P. YUASA YTX12-BS. I'll miss you.
