I have only had a wheelchair, supplied by NHS, for 2 months - the battery is showing signs that it is too tired to perform 100% !
I charged it fully on Thursday - went 1/2 mile to the shops and other than that, used it in the house to get to the downstairs toilet 10 times per day.
The LED's suddenly went from losing just two greens - to only 3 reds remaining, which rapidly dropped to 2 remaining - and the chair couldn't even climb a 1/2 inch step in to the conservatory !!
I have emailed my NHS contact…. but in the meantime, can't even trust the chair to get to the shops.
