I asked this in uk.people.disability but got no reply so know what a great bunch of people frequent this group, I beg your help.
Hi Everyone,
A friend of has had her batteries and charger stolen from her shed for her Tetra Booster mobility scooter.
A picture of the model can be found here:
Thank you most kindly.
Well assuming they're lead-acid, you'll definitely want "deep discharge" or "leisure" battery rather than "automotive" or "starter" battery.
No remaining clues about dimentions/capacity on any stickers on the scooter?
And Lidl had some "intelligent" switch-mode battery chargers about 2 weeks ago, which should suit. Probably sold out now, but worth a look if you're passing one.
I'd be asking the manufacturers/distributors. Failing that there appear to be people selling them new - I'd ask them if I couldn't find the source.
You might find this
cheers, clive
Ask here for Sam, he's the founder of Neves Mobility, 25-35 Birkbeck Rd, Sidcup, DA14 4DD 020 8300 1000
You will need 2 x 12V deep Discharge batteries, Measure the size of the hole they go in and I would guess 26 or 33 amp hour (Ah) batteries required and a maximum 3amp battery charger for 26Ah battery, maybe
5Ah for larger batteries, the bigger the charger the faster the charge time. h w l 26Ah 126 176 166 m5 bolt 33Ah 160 130 194 m6 bolt 44Ah 170 165 197 m6 bolt 55Ah 207 137 228 m6 boltsee

I don't know that particular model, but many (most? all?) of this type of vehicle have a non-standard battery pack designed for that make and model. This is to make it easy to install and remove the battery and hold it in place on/within the scooter.
Whilst the pack may have a perfectly standard and widely available battery within it, the entire pack is needed to match the scooter's connector(s) and mounting brackets. Unfortunately, as these packs aren't standard, the cost can be extortionate compared to the cost of the standard battery within it.
Buying the standard battery that is used within the pack is of little use - as it won't have the connectors needed to connect to the scooter or be safe to use without means to hold it securely in place.
Similar problems can exist with the charger. These are often fitted with a special connector, to plug into the scooter chassis, or plug into the battery pack. Another make and model of charger may again be of little use, as it will not fit the battery pack connector or a charge connector on the scooter.
Where standard batteries do come in useful is when the battery inside the battery pack has started to fail. This battery can be removed and a new one fitted, for far less cost than buying a replacement pack.
Of course, if you have the right skills available, it is possible to use standard batteries and a standard charger and make the modifications needed to the scooter to allow their use without the custom pack hardware. However, this is far from trivial. It is very important that the battery is held securely - if a bump causes the battery to move and for its contact(s) to touch metalwork, the result can be a fire and an explosion.
