We frequently get asked whether lithium batteries are really worth the money? Our answer every time is, yes they most definitely are.
Lithium batteries offer significant advantages over lead acid batteries including longer life span, improved discharge and charge efficiency, and being least 40% lighter in weight. We often hear that the higher price tag is off-putting, however per life cycle you will find that the TN Power lithium batteries are cheaper than lead acid. Below you will see a comparison between one of our very popular Hankook lead acid batteries and a TN Power lithium battery of the same capacity and as a result the outcome is lithium is the cheaper option:
| Hankook DC31 | TN Power TN100 | |
| Battery Capacity | 100Ah | 100Ah |
| Depth of Discharge Recommended | 50% | Can go to 100% |
| Useable Power | 50Ah | 100Ah |
| Life Cycles | 200 @ 50% depth of discharge | 7000 @ 50% depth of discharge |
| Price of Battery | £81.08 | £699 |
| Price per Cycle | 40p | 9p |
Key benefits of the TN Power lithium range
