Lawn Mower Batteries move with the Times?

Lawn Mower batteries

Britain has experienced one of the mildest winters on record and for us gardeners it is the beginning of the grass cutting season. I am never sure whether or not the weather has anything to do with the grass cutting time or the increase in the length of the daylight hours that causes the grass to start growing, I know that they say it is when the temperature reaches 6 C, but as I say I am not too sure. Some say that grass never really stops growing but the cold winter temperatures slow it down during the winter months.

However there I was cutting my lawn with my trusty 10 year old Mountfield petrol driver mower, belting out smoke as it struggled with the length of the grass and thought about what type of mowers were on the market place today? I was thinking that perhaps the lawn mower had moved on with times, the same as cars were doing and perhaps going from petrol engines to battery driven mowers.

At the moment we sell a large diversity of batteries for different types of lawnmowers. These lawnmower batteries are used primarily as starter batteries, are thus made in a similar fashion to car batteries, they are starter batteries and not storage batteries. They come in all shapes and sizes from 12volt 4.5amp up to a 12volt 24amp AGM or a 038 battery that are used on some of the older cars.

These types of lawnmower usually have an alternator fitted to charge the battery when the engine is running, but a backup smart charger is always handy to have, for if you do not have a long engine running time or have say a small lawn to cut and the engine does not have enough time to charge and recover the battery. Also a smart charger should be connected up to your battery in the dormant winter season, preferably in a frost free garage or out building. This will keep your battery fully charge and in top condition, up to the point of re using it again in spring.

If you battery has an alternator to charge the battery and you suspect that it may not be working, then it is easy to check with a simple and cheap voltmeter. Simply run the engine at full speed and put your voltmeter across the battery terminals, the reading should be between 13 to 15 volts input, if it is not then you may have a charging system problem, it could also be a fuse or the starter solenoid. If the charging system is ok then you will probably need a new battery.

If you do need a new battery then the best thing to do is to get the exact information from your old battery, this is the same advice as for a car battery or a motor cycle battery. Get all the information from your old battery and also the measurements, length, width and height. This will help your battery retailer should there be a discrepancy with the part numbers. I always recommend that you buy a battery from a local supplier if possible, but there are some excellent battery suppliers of cheap batteries online now and they are usually delivered in a couple of days, depending on when you order your battery.

New types of lawn mower batteries

The latest type of mower that I was perhaps dreaming about is now on the market. It has all been possible because of the recent advances in other type of battery technology, such as Nickel Cadmium and Lithium-Ion. These lawn mowers are powered by the batteries, just like say your cordless drill. In my opinion the Lithium-Ion battery will give you a better service and will hold its charge for about 500 days, but will require charging after that time. Also the lithium-Ion batteries are lighter and smaller than the Ni-Cd batteries.

The new types of mowers are very clean, quiet and do not pollute the atmosphere like my petrol driven Mountfield mower, the also make little noise when you are cutting your lawn. To sum up battery-powered mowers are much quieter than petrol-driven mowers and are more economical as well, considering the extortionate cost of petrol. While the lawnmower batteries can be recharged a number of times, they eventually wear out, which means that consumers will need to purchase replacement batteries from time to time, still much cheaper than buying petrol.

These mowers are now being produced by many of the mower manufacturers, such as Mountfield and Black and Decker and only time will tell whether or not they will be as effective and reliable as my petrol driven now old fashioned mower.

I have worked for a couple for national tyre companies in my younger days, before starting my first business. I now own a garage and MOT testing centre, here in the UK called Pellon Tyre and Auto-centre, and I am a keen blogger about anything to do with cars and their related products that will help my business. We are members of Point-S and Motor-Codes and are also a Unipart Car Care Centre and of course Tyre-safe.
