Prices and availability updated on 24/09/2026
Based on the batteries we found for your vehicle, our experts help you pick the right one.
📋 What we found
For your MTD Products All 800 we found 6 compatible batteries. This list includes 2 Start-Stop batteries and 4 conventional batteries (non Start-Stop).
📏 Battery size
The list contains batteries in different sizes or capacities (Ah). In many cases both variants fit, but it's worth checking your compartment dimensions and the Ah of your original battery before buying. If in doubt, choose the one with higher capacity: provided the size fits, it gives more headroom for cold starts and accessories.
⚡ Battery type for your vehicle
Does your MTD Products All 800 have a Start-Stop system? It shuts the engine off at short stops (traffic lights, jams) and restarts it automatically when you release the brake/clutch. If your dashboard has an "A-OFF" button or an engine icon with a circular arrow, it has it.
How do I know if my car has Start-Stop?
Start the engine, let it idle with the brake pressed: if at a stop the engine shuts down by itself and restarts when you release the brake, it has it. You can also look for an "A-OFF" button on the dashboard or a circular-arrow engine icon.
What happens if I fit a conventional battery in a Start-Stop car?
The battery will drain within months because it cannot sustain continuous start-stop cycles. The alternator also works harder compensating and may be damaged. We do not recommend it.
⚠ Then you need a battery designed for Start-Stop (EFB or AGM). We have hidden the conventional batteries from the list: fitting them in your car would ruin the battery within months and could damage the alternator. The batteries below are built for the frequent charge/discharge cycles of Start-Stop.
💡 Great. You can buy either a conventional or a Start-Stop (EFB or AGM) battery: a Start-Stop battery is perfectly valid in a non-Start-Stop car and is actually more robust (longer life, better cold-start performance). It is just a bit pricier. On vehicles older than year 2000, an EFB is preferable to an AGM: legacy alternators charge at a fixed voltage without temperature compensation, and an AGM needs a more precise charging profile to avoid losing life quickly — an EFB tolerates the classic alternator profile better.
💡 If in doubt, play it safe: buy a Start-Stop battery (EFB or AGM). It works in Start-Stop cars and non-Start-Stop cars alike, lasts longer and avoids any risk. You only pay a few euros more than a conventional one.
🔋 Technology (AGM / EFB)
✓ All Start-Stop batteries in the list are AGM — the most advanced technology. Perfect if your current battery was AGM or EFB: AGM always replaces both. Remember to register it via OBD if your car has a BMS (BMW, Audi, VAG, Mercedes…) so the alternator charges it correctly.
📊 View AGM vs EFB vs Conventional — full comparison
Here are the key differences between the three starter battery technologies. AGM is the most advanced technology (and the priciest); EFB is the middle ground for basic Start-Stop; conventional (also called flooded lead-acid) is the classic choice for non-Start-Stop cars.
| AGM | EFB | Conventional | |
|---|---|---|---|
| Charge cycles | Up to 3× more Start-Stop cycles than a conventional (cycle endurance certified to VDA standard) | ~2× more Start-Stop cycles than a conventional (cycle endurance certified to VDA standard) | Designed for start + alternator, not for repeated cycles |
| Expected life | 5-7 years under average use | 4-5 years under average use | 3-4 years under average use |
| Start-Stop compatible | ✓ Yes, even advanced systems (regenerative braking) | ✓ Yes, basic and mid-range Start-Stop | ✗ No — degrades within months |
| Cold start | Excellent (higher CCA) | Very good | Adequate |
| Relative price | €€€ (highest) | €€ (mid) | € (lowest) |
| Recommended for | Premium cars with advanced Start-Stop, many electrical accessories, heavy urban use | Mid-range Start-Stop cars, mixed city/motorway use | Non-Start-Stop cars, standard use, tight budget |
| Replacement rule | Replaces AGM and EFB; NEVER use EFB where AGM was original | Replaces EFB and conventional; does NOT replace AGM | Only conventional; not suitable for Start-Stop |
⭐ Our recommendation

Does your car have Start-Stop?
Start-Stop switches the engine off at traffic lights. If your car has it, it needs an AGM or EFB battery.

Frequently asked questions
- The MTD Products All 800 may use different batteries depending on engine and equipment. We found 6 compatible batteries priced between 76,20€ — 156,95€. Check dimensions and positive terminal position before purchasing.
- Yes, you can install a higher capacity (Ah) battery as long as the physical dimensions fit your MTD Products All 800 battery compartment and the positive terminal position matches.
- Yes, we detected Start-Stop compatible batteries for your MTD Products All 800. If your vehicle has Start-Stop, it needs an AGM or EFB battery. An AGM must always be replaced with AGM. An EFB can be replaced with EFB or AGM. Never install a conventional battery in a Start-Stop vehicle.
- Use the search tool by selecting your vehicle's make and model. Our system automatically filters compatible part numbers verified by our technicians. If you have any questions, contact us via WhatsApp.
- As they are consumable items, car batteries have a 2-year warranty, truck batteries a 1-year warranty, and all others (motorcycle batteries, cyclic batteries, etc.) a 6-month warranty. If a battery has a manufacturing defect, it will be replaced at no cost to the user.
- Under normal circumstances, batteries usually arrive within 1 to 2 days of ordering. However, there are some cases where delivery may take a little longer: peak seasons (Black Friday, Christmas, etc.), palletized shipments, occasional stock shortages, etc.
- In mainland Spain and Portugal delivery takes 24 working hours if you order before 17:00 and the battery is in stock; for the Balearic Islands, the Canary Islands and other EU destinations allow 2 to 5 days. Batteries are shipped fully charged and ready to install.
- Batteries compatible with the MTD Products All 800 fall into the following categories, each with typical dimensions: Start-Stop starter battery: 205 × 90 × 165 mm (length × width × height). Conventional starter battery: 205–207 × 90–92 × 162–165 mm (length × width × height). Before buying, check the battery compartment size of your vehicle: a larger case will not fit even if the reference is technically compatible.
- ⚠ Then you need a battery designed for Start-Stop (EFB or AGM). We have hidden the conventional batteries from the list: fitting them in your car would ruin the battery within months and could damage the alternator. The batteries below are built for the frequent charge/discharge cycles of Start-Stop. 💡 Great. You can buy either a conventional or a Start-Stop (EFB or AGM) battery: a Start-Stop battery is perfectly valid in a non-Start-Stop car and is actually more robust (longer life, better cold-start performance). It is just a bit pricier. On vehicles older than year 2000, an EFB is preferable to an AGM: legacy alternators charge at a fixed voltage without temperature compensation, and an AGM needs a more precise charging profile to avoid losing life quickly — an EFB tolerates the classic alternator profile better. 💡 If in doubt, play it safe: buy a Start-Stop battery (EFB or AGM). It works in Start-Stop cars and non-Start-Stop cars alike, lasts longer and avoids any risk. You only pay a few euros more than a conventional one.
