A Lawnmower battery is the simplest of components which kicks starts the engine to get the blades spinning and the grass cutting. Even though there are hundreds of brands of lawnmower and ride on lawnmowers, the range of lawnmower batteries is relatively small, making finding the right battery for you easier than ever. The most popular ride-on lawnmower battery replacement is what we call a 12N24-3 or a 12N24-4 (positive right and left respectively) but these are also known as an 895, 896 or a U1R and U1. The slight variation in part number simply refers to the positive and negative terminal layout. When checking your ride-on mower battery replacement always check the original box to get the polarity the right way; you can judge a battery’s layout by placing it on the floor with the terminals closest to your feet, note if the positive (red) terminal is on the left or right.
Another popular lawnmower battery is a 33Ah box size, the Haze part number is HSC12-33. Haze batteries have been used as original equipment on Countax ride-on lawnmowers, with the HSC12-33 most commonly fitted. It has a high CCA (cold cranking amps) of 350, this gives the battery the starting power it needs. Most lawnmower batteries are 12volts.
The Haze range consists of 5 main part number prefixes, HZS, HZB, HZY-EV, HZB-EV and HSC. The HZS and HZB batteries are used for standby applications as they have a long-lasting slow releasing power. The HZB-EV and HZY-EV are used for mainly for electric vehicles, due to their deep cycle capability. HZB-EV are AGM batteries and HZY-EV are Gel Batteries. The HSC range is used mainly in the Lawn and agricultural market as it has a 5 year design life and high CCA starting power.
One of the main reasons your mower needs a replacement battery is due to their seasonal use; over the winter period when you don’t need to cut the grass a battery can become flat. Most lawnmower batteries are charged in a similar way to a car battery with the use of an alternator, therefore if the mower battery is not used over the winter or dry periods in the summer, the battery will slowly self-discharge (go flat) and it may sulphate. Sulphation is the crystallisation of sulphur which in prolonged periods of discharge, deposit on the negative plates; this reduces the battery’s active material, which is responsible for its performance. It is not a manufacturers fault and is due to general wear of the battery or misuse.
Here are some hints and tips to help prevent sulphation:
When storing your engine starter battery for the winter period, ensure the battery is fully charged (a fully charged battery is 12.69volts), then either disconnect the battery from the machine or remove it altogether. Store your battery in a cool, dry, frost-free environment.
If stored, unused for more than 3 months check the batteries voltage, if this has fallen below 12.6V charge it again.
To help reduce sulphation have a look at our chargers available, a trickle charger is partially useful for these batteries, as when fully charged it can be left connected to keep the voltage from falling again in these prolonged periods of storage.
