Good replacement at a good price.
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.

Used on my Mountfield
Last battery lasted over 15 years but finally died. This turned up quicker than expected - I took it out the box and fitted it straight onto the mower without checking the voltage or connecting it to my battery charger. beforehand. Turned the key and she fired straight up! Very pleased...even comes with a spare set of bolts and washers to connect the leads.

Excellent Value
Nothing complicated to say here. Battery was dispatched and arrived very quickly. The price was very competitive and it came fully charged. Easy to fit as it was an exact replacement for the old unit. Buy with confidence.

New Battery, great price good delivery service and mower now works as before.
The original mower supplier wanted £90 plus carriage to replace the original Mountfield battery. At this price the Ultramax looks to be a bargain, less than half the price and no additional carriage charge. The battery was as described and delivered in the quoted time window by a carrier, despite there being no carriage charge. So far so very good only time will tell how good a buy this proves to be. 2022 and after the pre season charge up the battery enters its fifth year still working fine.
