OPTIONS AND CHOICES Do you ever wake up and realise you forgot to plug your tiny "all night" 5 Amp or 7 Amp manufacturer supplied battery charger? Or want to go out for a 10 mile "walk" with the dog in the evening (or to the pub/night club etc - or both) and then realise you dare not try it. Because you have been shopping all day and your batteries are at less than their best? :( You are not alone! It used to happen to me too! It just requires a little planning! I have various systems in place that cure all of the above battery issues, and make my batteries last around twice as long in real terms before replacement This is what I now do:
In fact every time I drive I always plug-in and get a free/fast top up, even if only going a couple of miles. I like charged batteries! You never know what may happen. Ever get asked to a party, or miss the ride home? Or break down... A full charge make your batteries and you feel better!
I charge at 12v in PARALLEL via my Anderson connection setup every night. It ensures that one battery isn't at a different state of charge than the other every time you charge them up. A normal single 24v charger (as you are currently using), only sees the total voltage of both batteries. So cuts off when it sees the correct finished voltage. But that's often with one battery a little overcharged and the other one undercharged. Both are bad for your batteries! Overcharging uses up electrolyte. Undercharging reduces range and causes sulphation of the plates. Advanced Chargers like this Hyperion that I use offers a multitude of options for the knowledgeable user. I can charge a powerchair from a car, a car from my powerchair and in fact any battery size and type so far invented. And graph battery charge and capacity and other details on the PC... For GEEKS! I have one! Actually three... Here
ALL of these charging methods will work fine on Gel or AGM wheelchair batteries. But the higher amp / faster charging systems work hugely better and faster/safer with the AGM Starter/Deep cycle combination batteries like Optima Yellow Top and Hawker Odyssey batteries. I can charge powerchairs quickly, from the wall, from the car, from each other, and I can even use them to start my van. Or connect an inverter for cutting the lawn... CHOICE! It gives you OPTIONS! |
