If you a stairlift userm, one of the parts that you will need to replace before all others is the battery. Stairlifts are designed to last for many years but the batteries reach end of life within a year or two at best and then they need to be replaced on a regular basis. It is also crucial to always check the condition of the battery to ensure no leakage as it may damage the electronic parts inside.
The average stairlift is powered by either two or more batteries that are located in the carriage itself. The other location for the batteries is in a box at the base of the system. The batteries are 12V lead acid batteries. Most stairlifts for children and adults have 7Ah batteries whereas those that serve heavier load such as wheelchairs have more powerful 12Ah batteries and they may even have three batteries instead of two.
Buying Stairlift Batteries
Most devices on the market use standard batteries that are mounted in standardised enclosures. Whether you are looking for batteries for Bruno, Acorn or Bison stair lift, chances are the same battery will do for all the brands. You need to check though whether your stairlift takes 7Ah or 12Ah batteries and how many it needs. Once done you can go to sites like batterysharks.com that specialise in replacement batteries for all makes and models of stairlifts.
Prices Of Stairlift Batteries
For a regular 7Ah battery you can expect to pay between $75 and $100 depending on the discount you get and the brand you go for. Yuasa and Panasonic are two of the best brands to go for and a quick way to check the quality of a battery is to feel its weight. More weight equals more lead in the lead acid battery and hence better power capacity as well as life expectancy.
Replacing Stairlift Batteries
Consult the manual that came with your stair lift before replacing batteries yourself. If the model was designed to have user replaceable batteries you can go ahead and follow the instructions. If the manual says that the batteries must be replaced by a professional you should have an electrician do the job. If you are replacing batteries yourself, always make sure you disconnect the mains connection and do not reverse polarity on the batteries as they may cause short circuit. Also lead acid batteries must always be kept upright to prevent leakage.
