There is another size battery that uses the same serial code but is a completely different shape, so please do look at the dimensions before ordering, the link to the other one will be in the alternatives tab.

We are also able to offer this size battery as an upgrade to a popular high energy starter that has a good following, it has a whopping 7ah of capacity and higher CCA so well worth investing in. You can add it as an upgrade above.

The details mentioned here are to act as a guide, you should check your old battery and compare it to this compatible one before ordering, this might save you a lot of time in the long run.

Looking after your battery is important if you do not want to have to change it every spring. Charge when it arrives and first use. During the summer if it's being used every few weeks it will probably pretty much look after itself, as long as its having good runs after every start. If they are only short runs then the energy might not be replensihed so a top up charge may be required.

Now it's during the offseason where it will go wrong, if when those shorter days begin to set in if you just abandon the lawnmower to the garden shed with no care, then your battery will have a shorter life. If it's not being used it should be recharged every six weeks to ensure the cells are fresh for the following spring.

Voltage = 12v
Capacity = 5Ah @ 20Hr
Chemistry = AGM, sealed
