Product Features The MOTOPOWER MP00205A 12V 800mA Battery Charger allows you to connect the charger to the battery and leave it for maintenance indefinitely. Once the battery has reached a 100% charge, the chargers will automatically switch it's output voltage to a safe, storage/float level (13.6V+/-0.2V) that eliminates the need to worry about the damaging effects of overcharging. Pulse Current Recovery Mode In the Absorption Mode, the charger will give a 0.5Amp pulse current to charge and recover the battery until it's fully charged. In this stage, the charger will decrease the battery sulfation and improve the battery performance gradually. For several times charging, you will find the battery internal resistance is lower and the performance is improved.

It's unlikely a minibus has such a small battery. In fact, I don't know what cars will have such a small battery. **Q: do you manufacture a 6 volt version** A: No **Q: I have this charger. Just to clarify, when charging the red light is solid and flashing green means nearly charged and solid green fully charged ?** A: Yes you are totally correct. Great little charger as it will not overcharge, it cuts off when the solid green is lit. Adrian **Q: Can this be used while car alarm is still running as stored outside** A: Mine is, however, the unit it’s self needs to be out of the weather, I extended the power lead (using waterproof connectors bought on Amazon) to give me extra cable between the outside socket and the unit, the unit is kept under the bonnet, If you plan to use an extension lead, all of the power sockets need to be protected of course from the wet. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Intuitive Display *by F***Y on 12 March 2026* Great little charger supplied with a fused connector to attach directly to a battery, very handy to fit to my motorcycle. Also supplied with a set of insulated crocodile clips which connect to the charger output cable via the insulated connector. The LED display is clear and intuitive. If I have one small criticism, it's the lenght of the power lead which is quite short, this was mentioned in other buyers reviews, however, this did not affect my choice. Very pleased with this purchase. ### ⭐⭐⭐⭐⭐ Great item *by P***D on 13 February 2026* This item is worth the money as it does the job efficiently ### ⭐⭐⭐⭐ Reliable and Affordable, but Cable Needs Extending *by P***R on 10 January 2026* I used the MOTOPOWER MP00205A 12V 800mA fully automatic battery charger/maintainer on my Toyota RAV4 while it was left unused for about 45 days. I simply connected it to the car on the driveway, and when I returned, the 12V battery measured 12.6 V, the car started and drove perfectly, and there was no battery discharge or issues at all. The charger is easy to use, fully automatic, and very affordable at £18. It kept my OEM battery healthy without any need for upgrades or expensive replacements. One important note is that the cable is very short. I had to cut it and extend it by 2 metres to reach comfortably. If you do this, make sure to reconnect properly using electrical tape or solder the wires, and make it waterproof to avoid any risk of damage or short circuits. People should be aware of this before purchase. For anyone leaving their car idle for extended periods, this is a simple, reliable, and cost-effective solution. ## Frequently Bought Together - MOTOPOWER MP00205A 12V 800mA Fully Automatic Battery Charger/Maintainer - UK Plug - KUNCAN 25FT Sae to Sae 2 Pin Extension Cable DC Power 16awg Heavy Duty Battery Quick Disconnect/Connect Wire Harness with Sae Connectors with Dust Cap… - Dongge 2 PCS SAE Connector Motorcycle Battery Charger SAE Charging Cable SAE Quickly cuts The Plug to The 12V Ring Terminal Fuse Suitable for Charging Motorcycles Tractors Cars etc --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/53558325-mp00205a-12v-battery-maintainer](https://www.desertcart.hk/products/53558325-mp00205a-12v-battery-maintainer) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-05-25*
