Last summer I got my son a Oset trials bike, it's battery powered.

The batteries will now not take a charge and I need to buy new ones,
can anyone tell me the difference between a 12ah & a 14ah battery ?

Many thanks.

ah stands for amp hour. A 12 ah battery has less available energy than a 14 ah battery. Basically, a 14ah battery should last a bit longer than the 12 ah battery.

"A battery with a capacity of 1 amp-hour should be able to continuously supply a current of 1 amp to a load for exactly 1 hour, or 2 amps for 1/2 hour, or 1/3 amp for 3 hours, etc., before becoming completely discharged. In an ideal battery, this relationship between continuous current and discharge time is stable and absolute, but real batteries don't behave exactly as this simple linear formula would indicate. Therefore, when amp-hour capacity is given for a battery, it is specified at either a given current, given time, or assumed to be rated for a time period of 8 hours (if no limiting factor is given)." http://www.allaboutcircuits.com/vol_1/chpt_11/3.html

Hope this helps. Hi Darling, I'll be home in 10 mins. If I'm not back, please read this message again...

14ah lasts longer than a set of wheels on EV's car
