Roger Ford Posted September 28, 2015 Share Posted September 28, 2015 How are you aiming to get it out? Not the easiest job, and you really don't want to be getting it on you or your clothingBetter to get a local battery specialist to fill it , but be prepared to answer searching questions as to why you didn't just buy the battery from them in the first place.

Area Representative Paul Richards Posted September 29, 2015 Area Representative Share Posted September 29, 2015 A bit late if you have already ordered your battery, but you can get a banner battery delivered full of acid and ready to go from Tayna. Great service. Link to comment Share on other sites More sharing options...
Roger Ford Posted September 29, 2015 Share Posted September 29, 2015 You can buy a litre of battery acid from Amazon marketplace for less than six quid delivered. Be very careful when filling it though. Link to comment Share on other sites More sharing options...

thompster Posted October 1, 2015 Share Posted October 1, 2015 For reference you can't use acid from an old battery. As a battery discharges the sulphor in the sulpuric acid reacts with the lead plates, creating lead sulphate and water. When you charge the battery the process is reversed and the H20 turns back into H2SO4.Batteries generally fail either because the plates are mechanically damaged (e.g. through overcharging/heat) or because they've been left discharged (lead sulphate and water) which allows the sulphur to crystalise. The more time a battery spends at less than 100% charged the faster this will happen, hence why continuous chargers make batteries last for ever-ish.

When the battery is charged, the reverse occurs: lead sulphate and water revert to sulphuric acid and lead (and lead dioxide). When sulphation occurs, it's not the sulphur that crystallises but the lead sulphate.JV Link to comment Share on other sites More sharing options...
Rex Posted October 6, 2015 Share Posted October 6, 2015 I've had this problem with all my previous batteries. The guy at the battery outlet here tells me I need a dry cell. We found a Harley-Davidson battery that will fit and has 700 amps vs 400 for the previous ones. It is working great so far. I just had to make some slight modifications to the battery holder.
