UPP: What Households Should Know About UPP E-Bike Batteries

If you own a UPP e-bike battery, the government has warned that models U004 and U004-1 pose a serious fire risk and should not be used.

UPP is a maker of e-bike battery packs, and its batteries are not emergency power kit. They are the kind of lithium-ion battery a household may already own, and the government has warned that two UPP models pose a serious fire risk. If you have a UPP battery, the first thing to do is check its model number. Models U004 and U004-1 are deemed to pose a serious fire risk according to the Government1.

The official safety notice, case number 2401-0083, was notified by the Office for Product Safety and Standards and advises owners to stop using the battery immediately and dispose of it safely via their local household waste disposal site2. That advice is the centre of this page. Everything else, from charging to storage to what happens in a power cut, follows from it.

For a household getting ready for emergencies, a battery like this matters in two ways. It is a fire risk in the home if it is charged or stored badly, and it is not a substitute for a torch, a power bank or a radio when the power goes off. The sections below set out what UPP makes, what to do with it, and how to keep the rest of your emergency kit ready.

UPP safety notices and recalls

The UPP notice is a product safety report rather than a simple recall. It was notified by the Office for Product Safety and Standards under alert number 2401-0083, and the risk level recorded in the report is serious4. The notice covers UPP Battery E-Bike Battery Packs sold via Amazon, AliBaba, eBay, Made in China and Desertcart, with China given as the country of origin2.

The warning has been repeated. West Yorkshire Fire and Rescue Service carries the OPSS warning on dangerous UPP e-bike batteries, a repeat warning to stop using UPP batteries linked to multiple serious fires5. That repetition matters: if you saw the original notice in 2024 and put it to one side, the advice has not softened.

Checking for recalls is something every household should do periodically, not only for UPP kit. Fire services advise checking your appliances are not subject to a product recall by checking the Office for Product Safety and Standards alerts and recalls page6. For white goods, check for recalls or safety notices on the Electrical Safety First website6. Registering electrical items with the manufacturer means you can be told if a safety repair is needed6.

What UPP makes for UK households

The product the safety notice covers is the UPP Battery E-Bike Battery Pack. The notice lists two models, U004 and U004-1, and gives their battery types as 18650 for the U004 and 21700 for the U004-12. Those cell types are how you tell the two apart if the model number on the label is hard to read.

E-bike batteries sit within a wider group of lithium-ion devices that fire and rescue services warn about. South Wales Fire and Rescue Service describes these as batteries that can be recharged and range from mobile phones, vaping devices, e-bikes and scooters, vacuum cleaners, tablets, iPads and ear pods7. The same charging disciplines apply across all of them, which is why the advice below is worth applying to the whole house and not just to one battery.

UPP batteries are sold through online marketplaces rather than a UK high street chain, according to the notice: Amazon, AliBaba, eBay, Made in China and Desertcart2. That affects how you get support, because there is no shop counter to take the battery back to. Keep your order confirmation and any messages with the seller, and deal with the marketplace you bought through if you need to raise the matter.

UPP kit for power cuts

A UPP e-bike battery is not a household backup power supply. It is designed to drive a bike, it is the subject of a serious fire risk warning, and it should not be pressed into service to run lights or charge phones during an outage.

What a household actually needs for a power cut is set out by local resilience partnerships. West Yorkshire Prepared lists a torch and spare batteries, a wind up or battery-powered radio tuned into local news or a car radio, a power bank or solar charger, an analogue phone, warm clothes and blankets, and non-perishable food8. The Met Office gives the same short list in its storm advice: battery candles, torches and batteries, and a mobile phone power pack9.

Need during a power cutWhat to keep readyWhy it matters
LightTorch and spare batteries8Safe light without flames
News and warningsWind up or battery-powered radio, or a car radio8Local updates when the internet is down
Phone chargingPower bank or solar charger8Keeps a mobile working for calls
WarmthWarm clothes and blankets8Heating systems often stop with the power
FoodNon-perishable food8Meals without cooking

Build that kit around your household rather than around a bike battery. Our guide to power cuts walks through what happens and in what order, and the emergency kit page sets out what to keep ready as a baseline.

Charging UPP kit safely

A battery charging on a bare tabletop, well away from soft furnishings and exits
A hard, clear surface and an unblocked exit are the two things fire services ask for when charging.

If you own any UPP battery that is not one of the two affected models, or you are charging other lithium-ion kit in the home, the fire and rescue services give clear rules. Always use the manufacturer's approved charger, because using the wrong charger can cause the battery to overheat and a fire to start3. Never leave electrical items unattended when charging, and unplug them before going to bed or leaving home3. Never cover batteries while charging, as this can cause overheating and start a fire10.

The Office for Product Safety and Standards sets out a five step routine, and its fourth step is to charge in a safe place without blocking exits and always unplug your charger when you have finished charging11. London Fire Brigade adds that you should put your device on a hard surface like a table before you start to charge it up, and unplug the charger once the battery is full12.

If a battery swells, the instruction from London Fire Brigade is blunt: stop charging immediately13. A swollen cell is a battery that has already failed. Do not press it back into a case, do not try another charger, and do not leave it in the house while you think about it.

Storing UPP kit so it is ready for an emergency

Storage for a battery under a safety warning means keeping it out of the living space until it can be disposed of, not arranging it neatly for use. For the rest of your kit, the principle is that it should be within reach when the lights go out.

Local resilience advice is consistent on this. Prepare an emergency pack and keep it within easy reach if needed14. Make up a home emergency pack, prepare an evacuation checklist, and keep a basic emergency kit in your vehicle depending on the time of year15. Keep spare batteries at home in the event of an emergency16.

  • Keep spare batteries at home in the event of an emergency8
  • Prepare an emergency pack and keep it within easy reach if needed8
  • Keep the kit somewhere in the house where everyone can get to it16
  • Keep some of the kit in a waterproof bag in case you need to leave your home without notice14
  • Use plastic boxes or backpacks to keep the supplies together, in a designated place that all household members know17

Winter is when this matters most. Insulating pipes is standard winter preparation17, and a household that has its kit checked before the first storm is not hunting for a torch by phone light. Our storms and snow guide covers the seasonal side in more detail.

Using UPP kit safely during an emergency

During an actual emergency, the temptation is to improvise. Resist it with batteries. A power cut is not a reason to charge a suspect battery from a generator or a car, and a storm is not a reason to move a battery somewhere warmer and softer.

The general rules for the home still apply when the power is off. Fire services advise checking for product recalls and safety notices on your specific model periodically18, and the government's product safety alerts, reports and recalls list is the place to search19. If you have registered your appliances, you will be told when a safety repair is needed6.

For the household kit that does work in an emergency, keep it simple and tested. A first aid kit should be handy in case of an emergency20. Pet care items should be included if required21. A wrench or pliers to turn off utilities belongs in the kit21. None of that depends on a bike battery.

UPP support and warranty

The government notice does not publish a UPP support line, a warranty period or a repair service. What it does record is where the batteries were sold: Amazon, AliBaba, eBay, Made in China and Desertcart2. Your route to support therefore runs through the seller or marketplace you bought from, using your order records.

For any electrical product, the practical steps are the same. Register the item with the manufacturer so you can be contacted if a safety repair is needed6. Check the government's list of product safety alerts, reports and recalls, and register your appliances so that you can be notified if your product is recalled19. For white goods, check for recalls or safety notices on the Electrical Safety First website6.

If a battery has been recalled or is under a safety warning, a warranty claim is secondary to getting it out of the home safely. The notice's instruction is to stop using it and dispose of it safely2. Keep a record of what you did and when, in case the seller asks.

Disposing of old or damaged UPP kit

Disposal is the step most households get wrong, because a lithium-ion battery cannot go in the bin. The UPP notice advises owners to dispose of the battery safely via their local household waste disposal site, and to check first with their local centre whether it accepts this type of battery2.

Ring ahead before you travel: not every centre takes every battery type.

Fire services give the same direction for damaged or end of life batteries generally: if in doubt, always take them to your local household waste recycling centre, the tip1. Vaping device batteries should be disposed of safely at designated recycling facilities22, and damaged or worn-out batteries should be replaced promptly to reduce the risk of malfunctions and fires22. The Office for Product Safety and Standards has run a campaign highlighting the hidden dangers of improper charging, damaged batteries and binning vapes23.

Common questions

How do I find the model number on a UPP battery?

Look at the label on the battery pack itself. The government's safety notice for UPP e-bike battery packs lists two models, U004 and U004-1, and gives their battery types as 18650 for the U004 and 21700 for the U004-1. If the label is worn or missing, treat the battery as suspect and do not charge it. Take it to your local household waste recycling centre instead.

How do I contact UPP about a battery?

The government safety notice does not give a UPP contact address. It records that the batteries were sold through Amazon, AliBaba, eBay, Made in China and Desertcart, so your first route is the marketplace or seller you bought from. If you are worried about any electrical item in the home, your local fire and rescue service publishes electrical safety advice, and the Office for Product Safety and Standards publishes recalls and alerts.

How do I check whether my UPP battery has been recalled?

Search the government's product safety alerts, reports and recalls pages for UPP. The UPP e-bike battery pack notice carries the case number 2401-0083 and was notified by the Office for Product Safety and Standards. You can also check the Electrical Safety First recalls pages, which fire services point households to. Check periodically rather than once, because notices are added over time.

Can I make a warranty claim on a UPP battery?

The government notice does not set out UPP's warranty terms, so a claim would go through the seller or marketplace you bought from. What matters more for safety is that the notice advises owners to stop using the battery immediately and dispose of it safely at their local household waste disposal site, checking first that the centre accepts this type of battery.

Where can I get replacement parts for UPP kit?

The safety notice does not list spare parts or a parts service for UPP batteries. Because models U004 and U004-1 are deemed to pose a serious fire risk, replacing cells or a charger yourself is not a sensible route. The official advice is to stop using the battery and dispose of it safely, not to repair it.

Can I use a UPP battery in cold weather?

The safety notice does not give cold-weather instructions for UPP batteries. General winter preparation advice is to insulate pipes and keep an emergency pack ready, and fire services advise charging batteries on a hard surface, never covering them, and unplugging the charger when full. If a battery is damaged, swollen or has been dropped, stop charging it immediately.
