The Battery Is A Good Job Fits And Works Great Will Please !

Arrived on time and fully charged. Easy to fit and started first time so works fine on our Mountfield 1530 H. At £49.99 an excellent price compared to Mountfield. Early days so can’t comment on how long it will last but will report back if there’s a problem.
