All batteries aren’t the same – they differ, a lot, between brands and types.
It’s potentially a trap especially when changing out batteries if your existing charger rates fail to meet or exceed your new battery requirements.
Here are some simple tips / facts regarding battery charging…
First off you should understand “what voltage your batteries need to be charged at during the various charger stages”. For this information consult the battery manufacturer or obtain a specification sheet on the battery itself (possibly from the Internet).
Then check that your charger(s) meets the batteries Boost (sometimes called Absorption or Bulk) and Float requirements. If they don’t, we can assist.
- Generally you have an AC charger (one that works on 240 volts)
- Possibly a Solar Charger and
- Finally a BC/DC charger (one that works on 12 volts)
“If you spend a long time in float (maintenance stage) i.e. when you are plugged into 240 volts and if the charge rate is too high you can prematurely dry out your batteries”.
- Reducing battery Boost charging * time can improve battery life
- Increasing battery Boost charging * time can reduce battery life
** May require a charger upgrade?
Our testing procedure and some observations;
Initially we do a battery “load test” and despite seeing good voltages they often collapse quickly. Sometimes it’s an issue with the charger or battery protector but after a chat we usually find out that the battery was ONLY charged every 1-2 months thus after about 2-years it sulphates and collapses. For some customers who have kept their batteries either on permanent smart or solar chargers their batteries can be up to 7-9 year old…
