| I work for a UPS manufacturer and have used UPS batteries on cars and bikes with no major problems, although life and performance depends on the design of the battery. Although the Ah capacity may be the same some batteries are designed to be float charged for a long period, followed by a steady discharge (this is the type of battery used in UPS). Other types are designed to sit with no charge for a time, a sudden massive discharge then high current recharge (this type is used in vehicles).
It makes me wince when I see people paying £90-100 for a 12v 17Ah battery for a bike when £100 will get me a 160Ah UPS battery and a 12v 17Ah battery is about £20! (OK, we buy thousands of them a year... but you see what I mean). |
