What to consider when buying a battery tender?
Battery tenders are vital if you want to prolong your battery’s life. There are battery tenders that allow multiple batteries to be charged at the same time so it may be cost effective to invest in one if you need more batteries maintained at the same time.
It’s important to decide the battery size you need. A charger with a high amp will be able to charge batteries faster but if you are not in a hurry you can also pick a charger of fewer amps and charge slower. Make sure the charger you pick have good safety features like spark-proof clamps and reverse-polarity protections as this will come in hand to prevent ruining a battery through overheating or even an explosion.
Pick a battery tender from a reputable brand so as to make sure you get a well-designed product that is backed by a long warranty. Most of the modern battery tenders have on-board microprocessors that will help you analyze and charge your batteries easily and picking a lightweight device will provide you with great portability when needed.
