I have the Shoprider Delux scooter.I brought it second hand.I put in a new battery but its not holding the charge. I seem to have to charge it up before any trips out.When its fully charged and I go about 50yards two bars are already gone.I would be grateful for advice.The scooter is about 4/5 years old.Thank You.

Yvonne,

When you say that you put in a new battery, I hope you mean new batteries. This particular scooter takes 2 batteries and just changing one will leave the remaining one in poor condition. Make sure that you have replaced the batteries with the correct size and type. This scooter takes 2, 40 amp hour batteries. Sealed gel AGM batteries are preferred. The batteries should have the number 40 on them with a date code. You need new, fresh batteries to have them work properly. A date code tag of A1 indicates the A month(1st month) or January of 2011 (1 is for 2011). If you are not sure of the battery condition a local shop can load test them for you.
There is a possibility with a 5 year old scooter that a worn motor/brake will cause excessive current draw and drain your batteries. A qualified technician can determine this for you with a service call.
Hope this helps.

I would agree. AGM (absorbent glass mat) lead acid batteries
deteriorate with time, just sitting around. If they are being used
(charged/discharged0 that speeds up the batteries aging process
and at a certain point, the batteries may appear to take a charge
to their nominal voltage 12.6v x 2 = 25.2volts, but as soon as
you put a load on them, their capacity drops off rapidly.
Since both batteries age at the same rate, you must replace
both of them at the same time.
I replace my AGM 33ah batteries on my Pride XL scooter and my
wheelchairs about every 2 years to be safe and not run out
of battery capacity when I need it the most.
