Abso 3-in-1 40A Battery Charger 12V (AC / Alternator / Solar). FREE BTS-10K temperature sensor included.
Our price is the manufacturer's home-market RRP — what this gear sells for where it's made. Branded marine equipment in Thailand typically retails 15–90% above that, when prices are published at all. Ours doesn't.
An all-in-one battery charger that accepts a variety of input sources, including: AC, DC, and PV solar.
KISAE’s UC1240 is the ultimate all-in-one battery charger. Able to draw power from a variety of inputs sources to charge your house battery, these smart multi-stage chargers use advanced algorithms to rapidly and safely replenish large capacity Gel, AGM, Lithium and Flooded batteries to peak performance from your choice of input sources.
FREE battery temperature sensor included. Every compatible Kisae charger we supply ships with a free BTS-10K battery temperature sensor — temperature-compensated charging matches the charge voltage to your battery’s real temperature, which protects the battery and maximises its service life in tropical conditions. Fitted as standard on every unit we supply, because it makes a real difference to battery longevity in Thailand.

As a guide for Fullriver AGM banks: a 20 A charger suits 55–105 Ah, 40 A suits 115–160 Ah and 60 A suits 210–260 Ah. Bigger banks, or banks that must recharge quickly from a generator, step up to 100 A. Check your own numbers with the battery bank calculator, or tell us your bank on LINE and we will match the charger.
Yes. Lithium is one of the selectable battery types, alongside Gel, AGM and Flooded, and Program mode lets you set the charge voltage your battery maker specifies.
